                                                       GENF-EN099
Xyz Monster

Steelswarm Roach
DARK / Fiend-Type Xyz / Rank 4 / ATK 1900 / DEF 0
2 Level 4 monsters
When a Level 5 or higher monster would be Special Summoned: You can detach 1 Xyz Material from this card; negate the Special Summon and destroy it.
SECRET RARE

                                                       Rating: 2
The currently overhyped card because his effect doesn't stop the Normal Summon of any monster so I can Tribute Summon a Monarch or just Normal Summon Gene-Warped Warwolf and crush him.
 
                                                       GENF-EN098*
Spell Card

A Hero Lives
Normal Spell
When you control no face-up monsters: Pay half your Life Points; Special Summon 1 Level 4 or lower "Elemental HERO" monster from your Deck.
ULTRA RARE

                                                       Rating: 2
It can give you an extra Tribute or allow you to activate Mask Change but the steep price can cost you the Duel if the monster you bring out with it is destroyed.
 
                                                       GENF-EN097
Spell Card

Mask Change
Quick-Play Spell
Target 1 face-up "HERO" monster you control; send it to the Graveyard. Then Special Summon 1 "Masked HERO" monster from the Extra Deck with the same Attrribute.
COMMON

                                                       Rating: 2
You can send any HERO monster to the Grave and bring out any Masked HERO with the same Attribute but IMO, the only even remotely playable Masked HERO is Vapor.
 
                                                       GENF-EN096
Fusion Monster

Vision HERO Adoration
DARK / Warrior-Type Fusion / Level 8 / ATK 2800 / DEF 2100
2 "HERO" monsters
Once per turn: You can target 1 face-up monster your opponent controls and 1 face-up "HERO" monster you control, except this card; the opponent's targeted monster loses ATK and DEF equal to the ATK of your targeted monster, until the End Phase.
SECRET RARE

                                                       Rating: 2
He steals the ATK of your opponent's monsters and adds that to your targeted HERO monster but he's not allowed to use it on himself, leaving his rating at 2.
 
                                                       GENF-EN095
Fusion Monster

Masked HERO Vapor
WATER / Warrior-Type Fusion / Level 6 / ATK 2400 / DEF 2000
Must be Special Summoned with "Mask Change", and cannot be Special Summoned by other ways. This card cannot be destroyed by card effects.
SUPER RARE

                                                       Rating: 2
Good thing he can't be destroyed by card effects because he can't be brought back later via Monster Reborn or the like but that's only enough to give him 2 stars due to his summoning conditions.
 
                                                       GENF-EN094
Fusion Monster

Masked HERO Goka
FIRE / Warrior-Type Fusion / Level 6 / ATK 2200 / DEF 1800
Must be Special Summoned with "Mask Change" and cannot be Special Summoned by other ways. This card gains 100 ATK for each "HERO" monster in your Graveyard.
RARE

                                                       Rating: 1
Let him stay masked because no one will want to look at him because of his terrible stats and effect.
 
                                                       GENF-EN093*
Fusion Monster

Elemental HERO Nova Master
FIRE / Warrior-Type Fusion / Level 8 / ATK 2600 / DEF 2100
1 "Elemental HERO" monster + 1 FIRE monster
Must be Fusion Summoned and cannot be Special Summoned by other ways. If this card destroys an opponent's monster by battle: Draw 1 card.
ULTRA RARE

                                                       Rating: 1
He'd have something to go for if you could bring him back via Monster Reborn and it would somewhat justify him being Ultra but that's it for him if he's destroyed after being Fusion Summoned.
 
                                                       GENF-EN092
Effect Monster

Phantom Magician
DARK / Spellcaster / Level 3 / ATK 600 / DEF 700
When this card is destroyed by battle and sent to the Graveyard: You can Special Summon 1 "HERO" monster with 1000 or less ATK from your Deck in face-up Defense Position.
COMMON

                                                       Rating: 1
I see why he's called Phantom Magician. Probably died in battle very early and he should be left in peace because there's no monster he can pick up from your Deck that's any good.
 
                                                       GENF-EN091
Fusion Monster

Vision HERO Trinity
DARK / Warrior-Type Fusion / Level 8 / ATK 2500 / DEF 2000
3 "HERO" monsters
During the turn this card was Fusion Summoned, its ATK is double its original ATK. This Fusion Summoned card can attack 3 times during each Battle Phase. This card cannot attack your opponent directly.
SUPER RARE

                                                       Rating: 3
His Fusion Materials aren't specific at all and while he only attains double his ATK the turn he's Fusion Summoned and can't attack directly, he can still attack three times per Battle Phase.
 
                                                       GENF-EN090
Effect Monster

Elemental HERO Flash
LIGHT / Warrior / Level 4 / ATK 1100 / DEF 1600
When this card is destroyed by battle and sent to the Graveyard: You can banish this card and 3 "Elemental HERO" Monster Cards with different names from your Graveyard to target 1 Normal Spell Card in your Graveyard; add that target to your hand.
COMMON

                                                       Rating: 1
In a flash, he'll be gone and from more than just the field because his effect is terrible because for what it requires you to banish, you get only a Normal Spell Card.
 
                                                       GENF-EN089
Trap Card

Smashing Horn
Counter Trap
When a monster effect or Trap Card is activated that negates the Normal or Special Summon of a monster(s): Negate the activation and destroy it.
SECRET RARE

                                                       Rating: 1
This makes even Counter Counter look good because that card can negate more than this.
 
                                                       GENF-EN088
Spell Card

Painful Return
Normal Spell
Your opponent chooses 1 monster in your Graveyard. During the End Phase, add that monster to your hand.
RARE

                                                       Rating: 2
This isn't too bad if you only have good choices in your Grave for your opponent to choose from but you have to wait until the End Phase to get it and likely this'll be a dead draw.
 
                                                       GENF-EN087
Spell Card

Fish and Swaps
Normal Spell
Discard 1 card to target 2 of your banished Fish, Sea Serpent, or Aqua-Type monsters; add them to your hand.
RARE

                                                       Rating: 2
You could theoretically ditch another Fish, Sea Serpent or Aqua-Type monster while Dimensional Fissure/Macro Cosmos is active but that won't be enough for me to raise its rating any higher. 
 
                                                       GENF-EN086
Xyz Monster

Adreus, Keeper of Armageddon
DARK / Fiend-Type Xyz / Rank 5 / ATK 2600 / DEF 1700
2 Level 5 monsters
Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up card your opponent controls; destroy it.
SECRET RARE

                                                       Rating: 2
It lets you detach one of its Xyz Materials to destroy any face up card your opponent controls but this guy needs 2 Level 5 monsters and will only get to use the effect twice for the time being.
 
                                                       GENF-EN085
Synchro Monster

Orient Dragon
WIND / Dragon-Type Synchro / Level 6 / ATK 2300 / DEF 1000
1 Tuner + 1 or more non-Tuner monsters
When this card is Synchro Summoned: Target 1 face-up Synchro Monster your opponent controls; banish that target.
SECRET RARE

                                                       Rating: 2
The effect is only activated the turn it's Synchro Summoned but it can get rid of that pesky Stardust Dragon or Brionac.
 
                                                       GENF-EN084
Effect Monster

Pain Painter
DARK / Zombie-Type Tuner / Level 2 / ATK 400 / DEF 200
While this card is face-up on the field, its name is treated as "Plaguespreader Zombie". Once per turn: You can target up to 2 face-up Zombie-Type monsters you control, except this card; they become Level 2 until the End Phase. They cannot be used as Synchro Material Monsters, except for the Synchro Summon of a Zombie-Type monster.
SECRET RARE

                                                       Rating: 3
This guy was literally made to Synchro Summon with those hard-to-bring-out Zombie Synchros like Archfiend Zombie Skull and both of his effects can achieve that.
 
                                                       GENF-EN083
Effect Monster

Lost Blue Breaker
WATER / Sea Serpent / Level 3 / ATK 1400 / DEF 0
If there is another face-up Fish, Sea Serpent, or Aqua-Type monster on the field: You can Tribute this card to target 1 Spell/Trap Card on the field; destroy that target.
SECRET RARE

                                                       Rating: 1
A slower MST effect that requires the field to have another Fish Sea Serpent or Aqua-Type monster just to Tribute this guy and destroy 1 Spell or Trap Card. Let him/her forever remain lost in the garbage.
 
                                                       GENF-EN082*
Effect Monster

Piercing Moray
WATER / Fish / Level 4 / ATK 1500 / DEF 500
Once per turn: You can Tribute 1 Fish, Sea Serpent, or Aqua-Type monster; this card gains 600 ATK. If this card attacks a Defense Position monster, inflict piercing Battle Damage to your opponent.
ULTRA RARE

                                                       Rating: 2
The ATK boost is permanent and it has the piercing Battle Damage effect but overall not worth being Ultra since it's pretty weak with only one good effect.
 
                                                       GENF-EN081
Effect Monster

Sea Lancer
WATER / Beast-Warrior / Level 5 / ATK 1300 / DEF 1000
You can target any number of your banished Fish, Sea Serpent, and Aqua-Type monsters; equip them to this card. This effect can only be used once while this card is face-up on the field. If this face-up card on the field would be destroyed, you can destroy 1 of those cards, instead. This card gains 1000 ATK while equipped with a monster(s) by this effect.
RARE

                                                       Rating: 2
It can equip itself with all your other Fish, Sea Serpent and Aqua-Type monsters, giving it 1000 ATK for each and can avoid destruction by destroying one of its equip cards but being Level 5 hurts it and its rating.
 
                                                       GENF-EN080
Trap Card

Gravelstorm
Normal Trap
Target 1 Spell/Trap Card on each side of the field; return them to the hand.
COMMON

                                                       Rating: 1
With the Sept 2011 Banned list now taking effect, we get back Heavy Storm so there's no room for this except in a trash can.
 
                                                       GENF-EN079*
Trap Card

Raigeki Bottle
Continuous Trap
Each time a monster you control declares an attack, place 1 Thunder Counter on this card. You can send this card with 4 or more Thunder Counters to the Graveyard; destroy all monsters your opponent controls.
ULTRA RARE

                                                       Rating: 3
Talk about a one-sided card! You clear your opponent's field of monsters just by sending it with at least 4 Thunder Counters on it!
 
                                                       GENF-EN0078
Trap Card

Attention!
Normal Trap
Target 1 face-up Level 5 or lower monster your opponent controls; destroy all face-up monsters on the field with a different Level than it.
RARE

                                                       Rating: 2
The effect affects both sides of the field so you'll want to make sure you have no monsters with a different Level than the targeted monster. 
 
                                                       GENF-EN077
Trap Card

Tyrant's Tummyache
Continuous Trap
Activate by Tributing 1 monster. Neither player can Special Summon a Level 6 or higher monster. If you have 3 or more cards in your hand, destroy this card.
COMMON

                                                       Rating: 1
It doesn't stop Normal Summons of Level 6+ monsters, it affects both players and it self-destructs if its controller has at least 3 cards in their hand plus you have to Tribute a monster just to activate it! 
 
                                                       GENF-EN076
Trap Card

Curse of the Circle
Normal Trap
Target 1 monster your opponent controls; your opponent cannot Tribute it, or use it as a Synchro Material Monster.
RARE

                                                       Rating: 2
At least the effect doesn't end during the End Phase and isn't restricted to any particular monster your opponent controls. 
 
                                                       GENF-EN075
Trap Card

United Front
Counter Trap
When a Trap Card is activated while you control 2 or more face-up monsters with the same Level: Negate the activation and destroy it.
RARE

                                                       Rating: 2
It has to be activated when a Trap Card is activated but its activation requirements aren't too steep.  
 
                                                       GENF-EN074
Trap Card

Utopian Aura
Normal Trap
Detach 1 Xyz Material you control; the face-up Xyz Monsters you control cannot be destroyed by card effects until the End Phase.
COMMON

                                                       Rating: 2
Save Utopia or Gachi Gachi from being destroyed by your opponent's card effect threats but being a Trap Card and having to detach an Xyz Material hurts this card's playability and rating.
 
                                                       GENF-EN073
Trap Card

Treaty on Uniform Nomenclature
Normal Trap
If you control 2 or more face-up monsters with the same name, except Tokens: Apply this effect, depending on how many you control.
● Exactly 2: Destroy 1 Spell/Trap Card your opponent controls.
● Exactly 3: Destroy all Spell/Trap Cards your opponent controls.
COMMON

                                                       Rating: 2
It's not limited to any 2 copies of the Ojamas thankfully so I can use multiple Krebons or heck any 2 copies of a monster but in most cases, you'll only destroy 1 opponent's Spell or Trap Card.
 
                                                       GENF-EN072
Trap Card

Burgeoning Whirlflame
Counter Trap
When a Trap Card is activated: Send 1 "Laval" monster from your hand to the Graveyard; negate the activation and destroy it. If this card is in the Graveyard: You can banish 2 FIRE monsters from your Graveyard; add this card to your hand.
COMMON

                                                       Rating: 1
There's no activation cost except to discard a Laval monster from your hand but I wouldn't have put an activation cost into a bad card like this one.
 
                                                       GENF-EN071
Trap Card

Past Image
Normal Trap
If you control a face-up Psychic-Type monster: Target 1 monster your opponent controls; banish it. During the next Standby Phase, it returns to the opponent's side of the field in the same Battle Position.
COMMON

                                                       Rating: 1
You may not need to discard anything but you need to have a Psychic-Type monster out and being a Trap Card, it'll take longer to use. Worse yet, the monster comes back later. Stick to Dark Core over this.
 
                                                       GENF-EN070
Trap Card

Bright Future
Normal Trap
Target 2 of your banished Psychic-Type monsters; return both those targets to the Graveyard and draw 1 card.
RARE

                                                       Rating: 2
Can come in handy if you just brought out Ultimate Axon Kicker or Chaos Sorcerer but Burial from a Different Dimension can return any 3 of your banished monsters back to your Grave and is Quick-Play.
 
                                                       GENF-EN069
Trap Card

Oh F!sh!
Counter Trap
When an Effect Monster's effect activates: Shuffle 1 of your banished Fish, Sea Serpent, or Aqua-Type monsters into the Main Deck; negate the activation and destroy it.
RARE

                                                       Rating: 2
It only negates Effect Monster effects and you can't just shuffle the monster types from anywhere (Deck, Grave, Hand) so you won't always have banished monsters to return for its activation requirement.
 
                                                       GENF-EN068
Trap Card

Underworld Egg Clutch
Normal Trap
When a face-up Fish, Sea Serpent, or Aqua-Type monster you control is banished: Add 1 Level 4 or lower Fish, Sea Serpent, or Aqua-Type monster from your Deck to your hand.
COMMON

                                                       Rating: 2
It's easy to get one of your Fish, Sea Serpent or Aqua-Type monsters banished if destroyed by battle while Dimensional Fissure is active unless Jinzo or Royal Decree is also face up.
 
                                                       GENF-EN067
Trap Card

Overwind
Normal Trap
Target 1 face-up "Wind-Up" monster you control; its ATK and DEF are doubled, and it returns to the hand during the End Phase. You can only activate 1 "Overwind" per turn.
COMMON

                                                       Rating: 2
If you've got game and your opponent can't stop you when you activate this, then the downside doesn't matter but if they can, you may be in trouble.
 
                                                       GENF-EN066
Trap Card

Damage Vaccine Ω MAX
Normal Trap
When you take damage by battle or by a card effect: Gain Life Points equal to the damage you took.
COMMON

                                                       Rating: 3
It applies to any kind of damage and you gain back all that you lost!
 
                                                       GENF-EN065
Trap Card

Explosive Urchin
Continuous Trap
Activate only when your opponent activates a Trap Card. During your Standby Phase: Inflict 1000 damage to your opponent. Your opponent must control a face-up Trap Card for you to activate and resolve this effect. During your 3rd End Phase after activation, send this card to the Graveyard.
COMMON

                                                       Rating: 2
There's one obvious Trap Card that would meet this card's requirements but defeats the purpose of activating this yet this card's activation requirements aren't hard to achieve.
 
                                                       GENF-EN064
Trap Card

Poseidon Wave
Normal Trap
When an opponent's monster declares an attack: Target the attacking monster; negate that target's attack, and if you control any face-up Fish, Sea Serpent, or Aqua-Type monsters, inflict 800 damage to your opponent for each of those monsters.
COMMON

                                                       Rating: 2
In most cases, you'd just be negating the attack but for that Negate Attack and Threatening Roar are better so you're better off keeping this in WATER Decks.
 
                                                       GENF-EN063
Trap Card

Asleep at the Switch
Normal Trap
When your opponent gains Life Points: Target 1 monster your opponent controls; destroy that target.
COMMON

                                                       Rating: 2
It's anti-LP Gain Decks but if Prime Material Dragon is out, this card is useless unless its controller has no cards to discard for PMD.
 
                                                       GENF-EN062
Spell Card

Peeking Goblin
Normal Spell
Your opponent reveals the top 3 cards of their Deck. Choose one to place on the bottom of the Deck and place the other two on top of the Deck in any order.
COMMON

                                                       Rating: 2
Know what's coming next and mess with your opponent's strategy but it's a bit of a gamble since you have no idea what cards are next in your opponent's Deck.
 
                                                       GENF-EN061
Spell Card

Resonance Device
Normal Spell
Target 2 face-up monsters you control with the same Type and Attrribute; change one of their Levels to the current Level of the other, until the End Phase.
RARE

                                                       Rating: 2
Use only for themed Decks because of this card's somewhat steep activation requirements.
 
                                                       GENF-EN060
Spell Card

Oni-Gami Combo
Normal Spell
Target 1 face-up Xyz Monster you control and detach all of its Xyz Material; this turn, that target can attack twice during the same Battle Phase.
COMMON

                                                       Rating: 2
I suppose you could steal your opponent's Xyz Monster then use this to remove it's Xyz Materials to make it less of a threat to you when you give the monster back but overall pretty poor.
 
                                                       GENF-EN059
Spell Card

Star Changer
Quick-Play Spell
Target 1 face-up monster on the field and activate 1 of these effects;
● Increase that target's Level by 1.
● Reduce that target's Level by 1.
RARE

                                                       Rating: 2
More of a disruption card than anything else, being a Quick-Play Spell.
 
                                                       GENF-EN058
Spell Card

Quill Pen of Gulldos
Normal Spell
Target 2 WIND monsters in your Graveyard and 1 card on the field; shuffle both of those first 2 targets into your Deck and return the other to the hand.
SUPER RARE

                                                       Rating: 2
Your best bet is to use this only in Decks where the majority or more of your monsters are WIND so you will be more likely able to activate this but you'll also need another card on the field to return to the hand.
 
                                                       GENF-EN057
Spell Card

Vylon Filament
Equip Spell
Equip only to a "Vylon" monster. If the equipped monster attacks, your opponent cannot activate any Spell/Trap Cards until the end of the Damage Step. If this face-up card on the field is sent to the Graveyard: You can add 1 "Vylon" Spell Card from your Deck to your hand.
COMMON

                                                       Rating: 2
Once the powerful Vylon Disigma is released, this card will become more playable but in the very least it can pick up another copy of itself if destroyed.
 
                                                       GENF-EN056
Spell Card

Future Glow
Continuous Spell
Banish 1 Psychic-Type monster from your Graveyard, and note its Level. All face-up Psychic-Type monsters you control gain ATK equal to that Level x 200.
COMMON

                                                       Rating: 2
The ATK boost is permanent like the card itself and you can use it multiple times per turn but unless it's Level 5 or more, your other monsters won't get much of a boost.
 
                                                       GENF-EN055
Spell Card

Fish and Kicks
Normal Spell
If you have 3 or more banished Fish, Sea Serpent, or Aqua-Type monsters: Target 1 card on the field; banish it.
COMMON

                                                       Rating: 1
There will be plenty of kicks to go around, literally as you'll have plenty of copies pulled from packs and you're sure to get a kick out of how bad the card really is.
 
                                                       GENF-EN054
Spell Card

Wind-Up Factory
Continuous Spell
Once per turn, if an effect of a "Wind-Up" monster is activated: You can add 1 Level 4 or lower "Wind-Up" monster from your Deck to your hand.
SUPER RARE

                                                       Rating: 2
This is almost a slower Black Whirlwind for Wind-Up monsters but since Wind-Up monster effects only activate once, you may not benefit from this card at all.
 
                                                       GENF-EN053
Spell Card

Legendary Wind-Up Key
Quick-Play Spell
Change all face-up "Wind-Up" monsters you control to face-down Defense Position.
COMMON

                                                       Rating: 2
Another Quick-Play that is probably going to be the main card of Wind-Up Decks because their effects are reset but it isn't what I consider legendary at all.
 
                                                       GENF-EN052

Cracking
Continuous Spell
Once per turn, when a monster(s) is sent from the field to the Graveyard by a card effect: Inflict 800 damage to the owner of the monster(s).
COMMON

                                                       Rating: 2
In multiples, this could put the hurt on either player but it's easy to work around like with Synchro Summons.

Infected Mail
Continuous Spell
Once per turn: You can target 1 face-up Level 4 or lower monster you control; it can attack your opponent directly this turn. Send it to the Graveyard at the end of the Battle Phase.
SUPER RARE

                                                       Rating: 3
You may lose the monster at the end of the Battle Phase but it can be worth it with the right monster like Sangan or if your opponent would otherwise get it back like with Terror-Byte's effect.

Crashbug Road
Quick-Play Spell
Each player can Special Summon 1 monster from their hand with the same Level as 1 face-up Level 4 or lower monster they control.

Makes for an easy Xyz or Synchro Summon and is at least Quick-Play but it applies to both players.

Target 1 Level 3 or lower Fish, Sea Serpent, or Aqua-Type monster in your Graveyard; Special Summon it in face-up Defense Position.
SUPER RARE

                                                       Rating: 2
You'll have an extra monster to use for a Tribute, Synchro Summon or Xyz Summon but that's about it because you can't attack with it since it's Special Summoned in Defense Mode.
