Zexal Collection Tin
                                                               ZTIN-EN012
Effect Monster
Galaxy Knight
LIGHT / Warrior / Level 8 / ATK 2800 / DEF 2600
If you control a "Photon" or "Galaxy" monster, you can Normal Summon this card without Tributing. When you do: Target 1 "Galaxy-Eyes Photon Dragon" in your Graveyard (if possible); regardless, this card loses 1000 ATK, and if it does, Special Summon that target (if any) in face-up Defense Position. This ATK decrease lasts until the End Phase.
ULTRA RARE
                                               Rating: 1

Since Galaxy-Eyes Photon Dragon virtually never, or never, sees play and since his friends are pretty bad thus far, all this guy has is a Normal Summon without tribute effect and that's pretty bad overall.
 
                                                               ZTIN-EN011
Effect Monster
Galaxy Wizard
LIGHT / Spellcaster / Level 4 / ATK 0 / DEF 1800
Once per turn: You can increase this card's Level by 4 until the End Phase. You can Tribute this card; add 1 "Galaxy" card from your Deck to your hand, except "Galaxy Wizard".
ULTRA RARE
                                               Rating: 2
He can quickly make himself Level 8 or fetch another one of his friends but nothing else about him or his friends impress me yet.
 
                                                               ZTIN-EN010
Effect Monster
Dimension Wanderer
LIGHT / Spellcaster / Level 1 / ATK 0 / DEF 0
When a monster is banished by the effect of "Galaxy-Eyes Photon Dragon": You can send this card from your hand to the Graveyard; inflict 3000 damage to your opponent. You can only use the effect of "Dimension Wanderer" once per turn.
SUPER RARE
                                               Rating: 1
This guy needs to stop wandering because that often gets you not where you want to be and since GEPD is hardly ever used if at all, this guy will see even less use.
 
                                                               ZTIN-EN009
Effect Monster
Kuriphoton
LIGHT / Fiend / Level 1 / ATK 300 / DEF 200
During either player's turn: You can send this card from your hand to the Graveyard and pay 2000 Life Points; you take no damage this turn. If this card is in your Graveyard: You can send 1 "Photon" monster from your hand to the Graveyard, except "Kuriphoton"; add this card from your Graveyard to your hand. You can only use this effect of "Kuriphoton" once per turn.
ULTRA RARE
                                               Rating: 1
It saves your Life Points from damage but you're still down 2000 Life Points for using its effect so you're better off with Prime Material Dragon instead.
 
                                                               ZTIN-EN008
Effect Monster
Photon Slasher
LIGHT / Warrior / Level 6 / ATK 2100 / DEF 1000
If a face-up Xyz Monster is on the field, you can Special Summon this card (from your hand) in face-up Defense Position.
SUPER RARE
                                               Rating: 2
With Xyz Monsters so popular, you're bound to bring this guy out but with only 1000 DEF, it's unlikely he'll be on the field for long.
 
                                                               ZTIN-EN007
Effect Monster
Photon Satellite
LIGHT / Machine / Level 1 / ATK 0 / DEF 0
Once per turn: You can target 1 other "Photon" monster you control; the Levels of both that monster and this card become the combined current Levels of those 2 monsters.
SUPER RARE
                                               Rating: 2
You might be able to make two Level 8 monsters but unless you draw any Photon monsters to use this on, he'll be of no use.
 
                                                               ZTIN-EN006
Effect Monster
Photon Pirate
LIGHT / Machine / Level 3 / ATK 1000 / DEF 1000
You can banish 1 "Photon" monster from your Graveyard; this card gains 1000 ATK until the End Phase. You can use the effect of "Photon Pirate" up to twice per turn.
SUPER RARE
                                               Rating: 1
He can start off your turn with 3000 ATK but come turn's end, there's two less Photon monsters in your Grave and he's back to his weak old self.
 
                                                               ZTIN-EN005
Trap Card
Gagagashield
Normal Trap
Target 1 face-up Spellcaster-Type monster you control; equip this card to that target. Twice per turn, it cannot be destroyed by battle or card effects.
ULTRA RARE
                                               Rating: 2
It can go to any Spellcaster and protects it from any destruction twice but anything that targets without destroying can still send the monster packing.
 
                                                               ZTIN-EN004
Spell Card
Gagagaback
Quick-Play Spell
During the turn a "Gagaga" monster you control was destroyed by battle and sent to the Graveyard: Special Summon as many monsters from your Graveyard as possible that were destroyed by battle this turn, in face-up Defense Position, then take 600 damage for each monster Special Summoned by this effect. You can only activate 1 "Gagagaback" per turn.
SUPER RARE
                                               Rating: 2
Only your Gagaga monster needs to lose a battle and when it does, you can get back more than what you lost but you also lose 600 Life Points per monster brought back.
 
                                                               ZTIN-EN003
Xyz Monster
Number 19: Freezadon
WATER / Dinosaur-Type Xyz / Rank 5 / ATK 2000 / DEF 2500
2 Level 5 monsters
Once per turn, if an Xyz Monster you control would activate an effect by detaching an Xyz Material(s), you can detach 1 Xyz Material from this card instead of 1 of those Xyz Materials.
ULTRA RARE
                                               Rating: 2
I would've wanted to see some other bonus effect other than being able to give away its Xyz Materials because being Rank 5, his stats aren't all that good but if nothing else, you have extra Xyz Materials.
 
                                                               ZTIN-EN002
Xyz Monster
Number 61: Volcasaurus
FIRE / Dinosaur-Type Xyz / Rank 5 / ATK 2500 / DEF 1000
2 Level 5 monsters
Once per turn: You can detach 1 Xyz Material from this card to target 1 face-up monster your opponent controls; destroy that opponent's monster, and if you do, inflict damage to your opponent equal to the destroyed monster's original ATK. This card cannot attack your opponent directly during the turn you activate this effect.
ULTRA RARE
                                               Rating: 2
So he's got a built-in, one-sided Ring of Destruction but can only target face up monsters and even if he hits your opponent's last monster, he can't attack directly that turn.
 
                                                               ZTIN-EN001
Effect Monster
Dododo Warrior
EARTH / Warrior / Level 6 / ATK 2300 / DEF 900
You can Normal Summon this card without Tributing, but its original ATK becomes 1800. If this card attacks, negate all card effects that activate in the opponent's Graveyard, until the end of the Damage Step.
SUPER RARE
                                               Rating: 3
The only drawback in Normal Summoning it without tributes is its ATK become 1800 but that's still good enough to make this guy playable and his effect isn't too bad a bonus! 
Zexal Manga Volume 2
                                                               YZ02-EN001
Xyz Monster
Number 50: Blackship Corn
DARK / Plant-Type Xyz / Rank 4 / ATK 2100 / DEF 1500
2 Level 4 monsters
Once per turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster your opponent controls with ATK less than or equal to this card's; send it to the Graveyard, and if you do, inflict 1000 damage to your opponent. This card cannot attack the turn you activate this effect.
ULTRA RARE
                                               Rating: 2
It can get rid of pesky Marshmallons, Spirit Reapers and Fortress Warriors but it's out of luck if the monster is stronger.

Xyz Monster
Number 88: Gimmick Puppet of Leo
DARK / Machine-Type Xyz / Rank 8 / ATK 3200 / DEF 2300
3 Level 8 monsters
Once per turn, if you have no cards in your Spell & Trap Card Zone: You can detach 1 Xyz Material from this card, and if you do, place 1 Destiny Counter on this card. You cannot conduct your Battle Phase the turn you activate this effect. When 3 Destiny Counters are on this card, you win the Duel.
ULTRA RARE
                                               Rating: 1
Gimmick is right, this card has so many strings attached that there's nothing good about it! Exodia looks much more likely to claim an automatic victory than this card. 
 
                                                               JUMP-EN063*
Xyz Monster
Number 40: Gimmick Puppet of Strings
DARK / Machine-Type Xyz / Rank 8 / ATK 3000 / DEF 2000
2 Level 8 monsters
Once per turn: You can detach 1 Xyz Material from this card; place 1 String Counter on each face-up monster on the field, except this card. If you do, during your opponent's next End Phase: Destroy the monsters with String Counters, and if you do, inflict 500 damage to your opponent for each monster destroyed.
ULTRA RARE
                                               Rating: 2
He delivers String Counters to all other monsters in play and gets rid of those monsters, dealing 500 damage to your opponent for each but it doesn't activate until the end of your opponent's next turn.

2 Level 10 monsters
Once per turn: You can detach 1 Xyz Material from this card; inflict 2000 damage to your opponent.
ULTRA RARE
                                               Rating: 2
It requires you to literally go to high levels to bring him out and when you do, that's 2000 damage to your opponent for each successful effect activation.

ULTRA RARE
                                               Rating: 2
So here it is, a long-awaited anime card now real but nerfing it was pretty well inevitable yet its drawbacks can work to your advantage.
Shonen Jump
                                                               JUMP-EN061*
Effect Monster
Slifer the Sky Dragon
DIVINE / Divine-Beast / Level 10 / ATK ? / DEF ?
Requires 3 Tributes to Normal Summon (cannot be Normal Set). This card's Normal Summon cannot be negated. When Normal Summoned, cards and effects cannot be activated. During the End Phase, if this card was Special Summoned: Send it to the Graveyard. This card gains 1000 ATK and DEF for each card in your hand. When a monster(s) is Normal or Special Summoned to your opponent's side of the field in face-up Attack Position: That monster(s) loses 2000 ATK, then if its ATK has been reduced to 0 as a result, destroy it.
ULTRA RARE
                                               Rating: 4
Much like Effect Monster Obelisk, this one retained much of its anime effects and turned out to be very good. His downsides are minimal compared to his playability.

Xyz Monster
Digvorzhak, King of Heavy Industry
EARTH / Machine-Type Xyz / Rank 5 / ATK 3200 / DEF 2000
3 Level 5 monsters
Once per turn: You can detach 1 Xyz Material from this card; send the top 3 cards of your opponent's Deck to the Graveyard, then, if any monsters were sent to the Graveyard by this effect, destroy cards your opponent controls, up to the number of monsters sent.
ULTRA RARE
                                               Rating: 1
This so-called King is already dethroned by the better card known as Needle Worm, which when flipped forces the opponent to lose the next 5 cards of their Deck free of charge and is far easier to play.
Gx Manga Volume 9
                                                               YG09-EN001
Fusion Monster
Elemental HERO Escuridao
DARK / Warrior-Type Fusion / Level 8 / ATK 2500 / DEF 2000
1 "Elemental HERO" monster + 1 DARK monster
Must be Fusion Summoned and cannot be Special Summoned by other ways. This card gains 100 ATK for each "Elemental HERO" monster in your Graveyard.
ULTRA RARE
                                               Rating: 1
Even though it's easy to Fusion Summon, why waste your time and effort when it can't be revived later and gets a mere 100 ATK per Elemental HERO in your Graveyard without any other effects?
5Ds Manga Volume 4

Synchro Monster
Blackwing - Gram the Shining Star
DARK / Winged Beast-Type Synchro / Level 5 / ATK 2200 / DEF 1500
1 Tuner 1 or more non-Tuner monsters
Must first be Synchro Summoned. When this card is Synchro Summoned: You can Special Summon 1 Level 4 or lower non-Tuner "Blackwing" monster from your hand. Its effects are negated.
ULTRA RARE
                                               Rating: 1
The regular Blackwings do this guy's job much better and don't negate effects (minus Shura's effect).
Shonen Jump

Xyz Monster
Number 16: Shock Master
LIGHT / Fairy-Type Xyz / Rank 4 / ATK 2300 / DEF 1600
3 Level 4 monsters
Once per turn: You can detach 1 Xyz Material from this card to declare a card type (Monster, Spell, or Trap); that type of card (if Spell or Trap) cannot be activated, or (if Monster) cannot activate its effects, until the end of your opponent's next turn.
ULTRA RARE
                                                Rating: 2
So here's the first card of Shonen Jump ALPHA and it's a shame it has to go that way because its effect doesn't make up for it because it applies to both players and has sub-par stats.
Zexal Manga Volume 1

Xyz Monster
Kachi Kochi Dragon
EARTH / Dragon-Type Xyz / Rank 4 / ATK 2100 / DEF 1300
2 Level 4 monsters
Once per turn, when this card destroys an opponent's monster by battle and sends it to the Graveyard: You can detach 1 Xyz Material from this card; it can attack once again in a row.
ULTRA RARE
                                               Rating: 2
Its stats aren't very strong but what it can kill in battle may help you either take out another monster or deal direct damage to your opponent.  
5Ds Manga Volume 3
                                                               YF03-EN001
Effect Monster
Infernity General
DARK / Fiend / Level 7 / ATK 2700 / DEF 1500
If you have no cards in your hand: You can banish this card from your Graveyard to target 2 Level 3 or lower "Infernity" monsters in your Graveyard; Special Summon them from the Graveyard, but their effects are negated.
ULTRA RARE
                                               Rating: 1

Banishing this guy for two of his friends that lose their effects and are therefore only good for Summons is pretty bad and his stats only make him worse.

Synchro Monster
Catapult Warrior
EARTH / Warrior-Type Synchro / Level 5 / ATK 1000 / DEF 1500
1 Tuner + 1 or more non-Tuner monsters
Once per turn: You can Tribute 1 "Junk" monster; inflict damage to your opponent equal to the original ATK of the Tributed monster.
ULTRA RARE

                                               Rating: 2
It deals the whole ATK of the Tributed monster but with so few playable Junk monsters, you won't likely deal massive damage with its effect, especially since it deals the original ATK to the opponent.

With Honest still at 1, this'll help a bit but not with monster that are not both LIGHT and Dragon-Type.  
 
                                                               PRC1-EN022
Spell Card
Photon Sanctuary
Normal Spell
Special Summon 2 "Photon Tokens" (Thunder-Type/LIGHT/Level 4/ATK 2000/DEF 0) in Defense Position. These Tokens cannot attack or be used as Synchro Material Monsters. You cannot Summon other monsters the turn you activate this card, except for LIGHT monsters.
SECRET RARE
                                               Rating: 2
I'll certainly pick up one or two for my LIGHT Deck but unless you run high-level LIGHT monsters, the tokens won't do you much good, especially with no DEF and being Summoned in Defense Mode.

Synchro Monster
Void Ogre Dragon
DARK / Dragon-Type Synchro / Level 8 / ATK 3000 / DEF 3000

Synchro Monster
Gravity Warrior
EARTH / Warrior-Type Synchro / Level 6 / ATK 2100 / DEF 1000
1 Tuner + 1 or more non-Tuner monsters
When this card is Synchro Summoned: It gains 300 ATK for each face-up monster your opponent controls. Once per turn, during your opponent's Battle Phase: You can target 1 Defense Position monster your opponent controls; change it to face-up Attack Position, also it must attack this turn, if able.
SECRET RARE
                                               Rating: 2
Once he arrives, he can have up to 3600 ATK and can force any opponent's Defense Position monster to essentially commit suicide but he's still prone to card effects like Ryko.

Fusion Monster
Masked HERO Dian
EARTH / Warrior-Type Fusion / Level 8 / ATK 2800 / DEF 3000
Must be Special Summoned with "Mask Change" and cannot be Special Summoned by other ways. When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can Special Summon 1 Level 4 or lower "HERO" monster from your Deck.
SECRET RARE
                                               Rating: 2
He can do a bit more than Acid but since I don't consider all that many HERO monsters good, this won't have many choices IMO.
 
                                                               PRC1-EN018
Fusion Monster
Masked HERO Acid
WATER / Warrior-Type Fusion / Level 8 / ATK 2600 / DEF 2100
Must be Special Summoned with "Mask Change" and cannot be Special Summoned by other ways. When this card is Special Summoned: Destroy all Spell and Trap Cards your opponent controls, and if you do, all monsters they control lose 300 ATK.
SECRET RARE
                                               Rating: 2
He could be a game-ender but is easy to stop with a simple Effect Veiler and after that, he's just a Vanilla Fusion Monster, not to mention he cannot come back other ways, not that it'd do him any good.

Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by sending 1 face-up LIGHT Dragon-Type monster and 1 face-up LIGHT Fairy-Type monster you control to the Graveyard, and cannot be Special Summoned by other ways. Once per turn: You can declare 3 card names; reveal the top 3 cards of your Deck, add any of them that you named to your hand, also send the remaining cards to the Graveyard. This card's ATK and DEF are equal to the number of cards you added to your hand by this effect x 1000.
SECRET RARE
                                               Rating: 1
A high-level monster with high-level risks and a high-level TOS! Yeah you can manipulate his effect with cards like Pigeonholing Books of Spell but you're better off saving the deck space with other cards.

Rosaria, the Stately Fallen Angel
EARTH / Plant / Level 8 / ATK 2900 / DEF 2400
Cannot be Normal Summoned or Set. Must first be Special Summoned (from your hand) by banishing 2 Level 7 or higher Plant-Type monsters (one from your hand and one from your Graveyard). Once per turn, during your Main Phase: You can negate the effects of all other face-up cards currently on the field, until the End Phase.

LIGHT / Dragon / Level 7 / ATK 2500 / DEF 2000
When this card is Normal or Flip Summoned: Destroy all Set cards your opponent controls.
SECRET RARE
                                               Rating: 1
So basically one time, he destroys all of your opponent's set cards and that's not good enough for me to say he's worth using.

DARK / Warrior / Level 3 / ATK 0 / DEF 0
When you Normal Summon a Level 3 monster: You can Special Summon this card from your hand. This card cannot be used as a Synchro Material Monster.

He doesn't offer enough to make him worth running because you'll miss the timing if you Normal Summon Junk Synchron, then bring this guy out.

Synchro Monster
Scarred Warrior
EARTH / Warrior-Type Synchro / Level 5 / ATK 2100 / DEF 1000
1 Tuner + 1 or more non-Tuner monsters
Your opponent cannot target face-up Warrior-Type monsters for attacks, except this one. Once per turn, if this card would be destroyed by battle, it is not destroyed.
SUPER RARE
                                               Rating: 2
He won't be going from your opponent's first attack and can save your other Warriors from harm but Marauding Captain is still better as he's easier to bring out, especially with its lockdown potential.

Once per turn, during your Main Phase: You can inflict 300 damage to your opponent for each card on the field. This card cannot attack during the turn you activate this effect.
SUPER RARE
                                               Rating: 3
It can't attack the turn you activate its effect but that may not matter because it'll likely deal a large amount of damage each turn and you can bring it back later if it ever gets destroyed!

Machina Cannon
EARTH / Machine / Level 8 / ATK 0 / DEF 2200
Cannot be Normal Summoned or Set. Must first be Special Summoned (from your hand) by sending one or more Machine-Type monsters from your hand to the Graveyard. This card gains 800 ATK for each card sent to the Graveyard for this Special Summon.
SUPER RARE
                                               Rating: 2
You can bring him back after you've summoned him properly which is a risky move because you'll need to discard multiple Machines to make this guy a threat but he'll be vulnerable to monster destruction.

Fallen Angel of Roses
EARTH / Plant / Level 7 / ATK 2400 / DEF 1300

I can clearly see why she's a fallen angel, given her lack of a decent effect and she'll be falling further, likely into the nearest trash can.

Great Poseidon Beetle
EARTH / Insect / Level 7 / ATK 2500 / DEF 2300
If this card targets an opponent's face-up Attack Position monster for an attack, and that monster is not destroyed by the battle, this card can attack the same monster again in a row. This effect can only be used twice per turn.
SUPER RARE

It isn't going to use its effect too often but with Marshmallon now at 2, it'll get more out of it than it would beforehand.

Some prize card this turned out to be. These should be in mass quantities so they'll be a price they deserve to be not $500 or more.

He basically converts into a Goblin Attack Force with his effect and he can't take face up Attack Position monsters so he won't likely gain much ATK at all.

Tribute Summon him with Hardened Armed Dragon and another monster to really make use of this card, especially since it won't be affected by effects that destroy cards!

Not in the least bit superb by my standards since he does nothing when Normal Summoned and with only 2900 ATK, can get run over by BEWD.

"Asmo Token" cannot be destroyed by card effects. "Deus Token" cannot be destroyed by battle.

I consider this one to be the best of the three since it creates two tokens, one indestructible in battle, the other indestructible by card effects but this guy must be Special Summoned from the hand.

A pretty powerful Synchro Monster! He does have a minimal downside as he has specific Synchro Materials that he needs but once he's out, you have all Level 6 or lower DARK monsters at your disposal, literally!

Bringing this guy out is a pretty big gamble since you'll likely control other monsters out and you'd risk having this guy Bottomless'd from the game as you will try to make him as powerful as possible.

Bringing this guy out with 2 monsters may seem pretty bad for a Level 5 monster but if it destroys a monster, it gets 800 ATK and can attack again yet the ATK gain isn't permanent.

Since it will most likely only survive one turn, it will probably get to use its effect once, which isn't too bad but it's a still pretty bad card.
