Lord of the Storm (SD8-EN035)
Ninjitsu Art of Transformation
TRAP / Continuous Trap
Activate this card by Tributing 1 face-up monster on your side of the field that includes "Ninja" in its card name.

There's only 1 Ninja monster in the entire Deck, and there are no better alternatives.

Lord of the Storm (SD8-EN034)
Sakuretsu Armor
TRAP / Normal Trap

Reckless Greed
TRAP / Normal Trap
Draw 2 cards, and after that skip your next 2 Draw Phases.
(Common)

Dark Coffin
TRAP / Normal Trap

● Discard 1 random card in their hand.

Obviously meant to work with Hunting Ground, but they won't choose to destroy their own monster.

Lord of the Storm (SD8-EN031)
Magic Jammer
TRAP / Counter Trap
Discard 1 card from your hand. Negate the activation of a Spell Card and destroy it.

They'll need all the card negation they can get at this point.

Dust Tornado

Destroy 1 Spell or Trap Card on your opponent's side of the field. You can then Set 1 Spell or Trap Card from your hand.

An obscure video game promo is reprinted for the unlikely event a player has multiples of any monster out.

Lord of the Storm (SD8-EN027)
Hysteric Party

(Common)

Rating: 1 out of 5
Cyber Harpie Lady (#97) would be a decent card, but it's not here and otherwise hard to obtain.

Lord of the Storm (SD8-EN026)
Lightning Vortex
SPELL / Normal Spell
Discard 1 card from your hand. Destroy all face-up monsters on your opponent's side of the field.
(Common)

Lord of the Storm (SD8-EN025)
Triangle Ecstasy Spark
SPELL / Normal Spell
Until the End Phase of this turn, the ATK of all "Harpie Lady Sisters" becomes 2700, your opponent cannot activate any Trap Cards, and the effect of every Trap Card on your opponent's side of the field is negated.
(Common)

Rating: 1 out of 5
Not even the regular (#26) Harpie Lady can use this, and this was foil back in Rise of Destiny. (#39)

Lord of the Storm (SD8-EN024)
Harpies' Hunting Ground
SPELL / Field Spell
When "Harpie Lady" or "Harpie Lady Sisters" is Normal Summoned or Special Summoned to the field, destroy 1 Spell or Trap Card on the field. Increase the ATK and DEF of all face-up Winged Beast-Type monsters on the field by 200 points.

Lord of the Storm (SD8-EN021)
Elegant Egotist

Another dead draw to add to the list of awful choices.

Lord of the Storm (SD8-EN020)
Nobleman of Crossout

(Common)

Rating: 2 out of 5
Magical Mallet is better, but this could be useful outside this Deck.

Lord of the Storm (SD8-EN017)
Harpie's Pet Baby Dragon
WIND / Effect Monster / Level 4 / ATK 1200 / DEF 600
(Dragon / Effect)
This card accumulates effects according to the number of monsters on your side of the field that include "Harpie" in their names (other than "Harpie's Pet Baby Dragon" and "Harpie's Brother"). At least 1: While this card is face-up on the field, your opponent cannot select monsters on your side of the field as attack targets if they include "Harpie" in their card names (other than "Harpie's Pet Baby Dragon" and "Harpie's Brother"). At least 2: Double the original ATK and DEF of this card. At least 3: Once per turn, you can destroy 1 card on your opponent's side of the field.
(Common)

Rating: 1 out of 5
Is this Baby Dragon (#3) with effects?

(Winged Beast / Effect)
If you Tribute Summon this card by Tributing a WIND monster, return all Spell and Trap Cards on the field to the owners' hands.

Harpie Lady 3
WIND / Effect Monster / Level 4 / ATK 1300 / DEF 1400

(Common)

Rating: 1 out of 5

Harpie Lady 2
WIND / Effect Monster / Level 4 / ATK 1300 / DEF 1400

Lord of the Storm (SD8-EN012)
Roc from the Valley of Haze
WIND / Effect Monster / Level 6 / ATK 2400 / DEF 1400
(Winged Beast / Effect)

Lady Ninja Yae
WIND / Effect Monster / Level 3 / ATK 1100 / DEF 200

Lord of the Storm (SD8-EN010)
Silpheed
WIND / Effect Monster / Level 4 / ATK 1700 / DEF 700
(Fairy / Effect)
This card cannot be Normal Summoned or Set. This card can only be Special Summoned by removing from play 1 WIND monster in your Graveyard. When this card is destroyed as a result of battle and sent to the Graveyard, your opponent discards 1 random card from their hand.

Rating: 1 out of 5
It's like UDE wants this Deck to fail.

Birdface
WIND / Effect Monster / Level 4 / ATK 1600 / DEF 1600
(Winged Beast / Effect)
When this card is sent to the Graveyard as a result of battle, you can add 1 "Harpie Lady" from your Deck to your hand. Then shuffle your Deck.

No one even runs Harpie Lady (#145) so why have a monster that is exclusive to it?

Lord of the Storm (SD8-EN008)
Bladefly
WIND / Effect Monster / Level 2 / ATK 600 / DEF 700
(Insect / Effect)
As long as this card remains face-up on the field, increase the ATK of all WIND monsters by 500 points and decrease the ATK of all EARTH monsters by 400 points.

Taken straight from SD3, here's the fitting Attribute monster for this Deck.

Harpie Lady Sisters
WIND / Effect Monster / Level 6 / ATK 1950 / DEF 2100
(Winged Beast / Effect)
This card cannot be Normal Summoned or Set. This card can only be Special Summoned by the effect of "Elegant Egotist".
(Common)

Rating: 1 out of 5
What about Cyber Harpie Lady (#97)? A much better fit than this trio of rejects. Its only print was last year.

Lord of the Storm (SD8-EN006)
Flying Kamakiri #1
WIND / Effect Monster / Level 4 / ATK 1400 / DEF 900
(Insect / Effect)
When this card is sent to the Graveyard as a result of battle, you can Special Summon 1 WIND monster with an ATK of 1500 or less in face-up Attack Position from your Deck. Then shuffle your Deck.

Still better than how we started.

Slate Warrior
WIND / Effect Monster / Level 4 / ATK 1900 / DEF 400

A Harpie chick who aspires to flit about beautifully and gorgeously, but attack sharply.

A forgotten fairy from a Disney movie is more like it.

Lord of the Storm (SD8-EN003)
Sonic Duck
WIND / Normal Monster / Level 3 / ATK 1700 / DEF 700
(Winged Beast / Normal)
A duck which can walk at a sonic speed. Sometimes, he cannot deal with his incredible pace and loses control.

So far, this is Cyberdark Impact levels of bad.

Lord of the Storm (SD8-EN002)
Sonic Shooter
WIND / Effect Monster / Level 4 / ATK 1300 / DEF 600
(Winged Beast / Effect)
If there are no cards in your opponent's Spell & Trap Card Zones, this card can attack your opponent's Life Points directly. When it does, any Battle Damage this card inflicts to your opponent's Life Points becomes the original ATK of this card.
(Common)

Rating: 1 out of 5
Unless you're facing a newbie, this isn't going to be a threat.

Lord of the Storm (SD8-EN001)
Simorgh, Bird of Divinity
WIND / Effect Monster / Level 7 / ATK 2700 / DEF 1000
(Winged Beast / Effect)
This card cannot be Special Summoned. If you Tribute Summon this card, the Tributes must be WIND. While this card is face-up on the field, both players take 1000 points of damage during each player's End Phase. Decrease the damage each player takes when this happens by 500 points for each Spell and Trap Card that player controls.
(Ultra Rare)

Rating: 1 out of 5
The controller is just as much at risk of paying for the effect as the opponent.

Invincible Fortress (SD7-EN032)
Compulsory Evacuation Device
TRAP / Normal Trap
Return 1 monster on the field to its owner's hand.
(Common)

Rating: 2 out of 5
The last card to be reviewed, and it shows this is mainly a defensive Deck.

Invincible Fortress (SD7-EN031)
Reckless Greed
TRAP / Normal Trap
Draw 2 cards, and after that skip your next 2 Draw Phases.
(Common)

Rating: 2 out of 5
You'd better hope the draws are good.

Invincible Fortress (SD7-EN030)
Ordeal of a Traveler
TRAP / Continuous Trap
You can only activate this card's effect when your opponent declares an attack. Your opponent selects 1 random card in your hand and calls the type of the card (Monster, Spell, or Trap). If your opponent calls it wrong, the attacking monster is returned to its owner's hand.
(Common)

Rating: 2 out of 5
Only truly works when you have at least 2 cards in your hand.

Invincible Fortress (SD7-EN029)
Robbin' Goblin
TRAP / Continuous Trap
Each time 1 monster on your side of the field inflicts Battle Damage to your opponent's Life Points, your opponent discards 1 random card from their hand.
(Common)

Rating: 1 out of 5
Where's the punishment? The other player is only down 1 card and you're not looking at their hand.

Invincible Fortress (SD7-EN028)
Magic Drain
TRAP / Counter Trap
You can only activate this card when your opponent activates a Spell Card. Your opponent can discard 1 Spell Card from their hand to negate the effect of this card. If your opponent does not, negate the activation of your opponent's Spell Card and destroy it.
(Common)

Rating: 2 out of 5
You're down nothing while they lose a Spell Card, and it might almost be a better Magic Jammer.

Invincible Fortress (SD7-EN027)
Ultimate Offering
TRAP / Continuous Trap
By paying 500 Life Points, Normal Summon or Set 1 extra monster. You can only activate this effect during your Main Phase or your opponent's Battle Phase.
(Common)

Rating: 2 out of 5
Not too costly, unless you're using it multiple times.

Invincible Fortress (SD7-EN026)
Waboku
TRAP / Normal Trap
You take no Battle Damage this turn. Your monsters cannot be destroyed as a result of battle this turn.
(Common)

Rating: 3 out of 5
The last part is new, making this card actually pretty good.

Invincible Fortress (SD7-EN025)
Shifting Shadows
SPELL / Continuous Spell
Pay 300 Life Points to rearrange the face-down Defense Position monsters on your side of the field, then return them in face-down Defense Position. You can only use this effect once per turn.
(Common)

Rating: 2 out of 5
The Deck's support replicates the Pharaonic Guardian Rock monster strategy, which is okay.

Invincible Fortress (SD7-EN024)
Brain Control
SPELL / Normal Spell
Pay 800 Life Points. Select 1 face-up monster on your opponent's side of the field. Take control of the selected card until the end of this turn.
(Common)

Rating: 2 out of 5
Snatch Steal (SD4 #15) is at 1, this card is at 3. Pretty good indication of which is better.

Invincible Fortress (SD7-EN023)
Ectoplasmer
SPELL / Continuous Spell
Only once during each player's End Phase, the turn player Tributes 1 face-up monster on his/her side of the field and inflicts damage to the opponent's Life Points equal to half of the original ATK of the Tributed Monster.
(Common)

Rating: 1 out of 5
This Deck is ill-prepared for this card's effect and it's just bad overall.

Invincible Fortress (SD7-EN022)
Hammer Shot
SPELL / Normal Spell
Destroy 1 face-up Attack Position monster with the highest ATK on the field. (If it is a tie, you get to choose.)
(Common)

Rating: 2 out of 5
Being able to choose helps, but this is still risky.

Invincible Fortress (SD7-EN021)
Magical Mallet
SPELL / Normal Spell
Add any number of cards from your hand to the Deck and shuffle it. Then draw the same number of cards you added to the Deck.
(Common)

Rating: 3 out of 5
MUCH better than Reload (SD2 #23) by far.

Invincible Fortress (SD7-EN020)
Shield & Sword
SPELL / Normal Spell
Switch the original ATK and DEF of all face-up monsters on the field until the end of this turn. Any additions and subtractions to ATK and DEF due to card effects are applied to the new ATK and DEF. Monsters Summoned after this card's activation are excluded.
(Common)

Rating: 2 out of 5
There are uses with this, but I'm not sure it was best here.

Invincible Fortress (SD7-EN019)
Swords of Revealing Light
SPELL / Normal Spell
Flip all face-down monsters on your opponent's side of the field face-up. This card remains face-up on the field for 3 of your opponent's turns. As long as this card remains face-up on the field, your opponent cannot declare an attack.
(Common)

Rating: 3 out of 5
Pretty much a staple in Stall Decks, and useful overall.

Invincible Fortress (SD7-EN018)
Premature Burial
SPELL / Equip Spell
Pay 800 Life Points. Select 1 monster from your Graveyard, Special Summon it on the field in face-up Attack Position, and equip it with this card. When this card is destroyed, destroy the equipped monster.
(Common)

Rating: 3 out of 5
Works well for reviving stong monsters, but I doubt it's all that good in this Deck.

Invincible Fortress (SD7-EN017)
Mystical Space Typhoon
SPELL / Quick-Play Spell
Destroy 1 Spell or Trap Card on the field.
(Common)

Rating: 3 out of 5
It's been in just about all of the Structure Decks, and why not?

Invincible Fortress (SD7-EN016)
Canyon
SPELL / Field Spell
If a Rock-Type monster in Defense Position is attacked, double any Battle Damage to the controller of the attacking monster.
(Common)

Rating: 2 out of 5
Sounds good at first, but likely only to deal around 1000 damage per attack.

Invincible Fortress (SD7-EN015)
Sand Moth
EARTH / Effect Monster / Level 4 / ATK 1000 / DEF 2000
(Rock / Effect)
When this face-down Defense Position card is destroyed and sent to the Graveyard, except as a result of battle, switch the original ATK and DEF of this card, and Special Summon it to your side of the field.
(Common)

Rating: 2 out of 5
Okay on its own, and the effect might prove useful.

Invincible Fortress (SD7-EN014)
Medusa Worm
EARTH / Effect Monster / Level 2 / ATK 500 / DEF 600
(Rock / Effect)
Once per turn, during your Main Phase, you can flip this card into face-down Defense Position. When this card is Flip Summoned, destroy 1 monster on your opponent's side of the field.
(Common)

Rating: 2 out of 5
Being a reusable Man-Eater Bug (#46) could be useful, but this isn't a Flip-Effect monster.

Invincible Fortress (SD7-EN013)
Guardian Statue
EARTH / Effect Monster / Level 3 / ATK 800 / DEF 1400
(Rock / Effect)
Once per turn, during your Main Phase, you can flip this card into face-down Defense Position. When this card is Flip Summoned, return 1 monster on your opponent's side of the field to its owner's hand.

Rating: 1 out of 5
The Trap Card is quicker and more versatile.

Invincible Fortress (SD7-EN012)
Megarock Dragon
EARTH / Effect Monster / Level 7 / ATK ? / DEF ?
(Rock / Effect)
This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by removing from play a Rock-Type monster(s) in your Graveyard. The original ATK and DEF of this card become the number of Rock-Type monsters you removed from play when you Special Summoned this card x 700 points.
(Common)

Rating: 2 out of 5
Undefined stats generally come down to their effects, and this doesn't really have any.

Invincible Fortress (SD7-EN011)
Moai Interceptor Cannons
EARTH / Effect Monster / Level 4 / ATK 1100 / DEF 2000
(Rock / Effect)
Once per turn, during your Main Phase, you can flip this card into face-down Defense Position.
(Common)

Rating: 2 out of 5
Turning it face-down really doesn't add anything. Just Set it and forget it.

Invincible Fortress (SD7-EN010)
Criosphinx
EARTH / Effect Monster / Level 6 / ATK 1200 / DEF 2400
(Rock / Effect)
While this card is face-up on your side of the field, when a monster is returned from the field to the owner's hand, the owner of the returned monster selects 1 card in their hand and sends it to the Graveyard.
(Common)

Rating: 1 out of 5
Only 500 less ATK than Guardian Sphinx, but the effect just isn't good enough.

Invincible Fortress (SD7-EN009)
Hieracosphinx
EARTH / Effect Monster / Level 6 / ATK 2400 / DEF 1200
(Rock / Effect)
While this card is face-up on your side of the field, your opponent cannot select a face-down Defense Position monster as an attack target.
(Common)

Rating: 4 out of 5
A low-Level Beatstick that prevents your Set monsters from being attacked is great.

Invincible Fortress (SD7-EN008)
Golem Sentry
EARTH / Effect Monster / Level 4 / ATK 800 / DEF 1800
(Rock / Effect)
Once per turn, you can flip this card into face-down Defense Position. When this card is Flip Summoned, return 1 monster on your opponent's side of the field to the owner's hand.
(Common)

Rating: 2 out of 5
They probably would've been better off making new ones with this effect than using the old ones.

Invincible Fortress (SD7-EN007)
Stone Statue of the Aztecs
EARTH / Effect Monster / Level 4 / ATK 300 / DEF 2000
(Rock / Effect)
Double any Battle Damage your opponent takes when they attack this monster.
(Common)

Rating: 3 out of 5
Doubling battle damage can be enough to turn a 2-star rating into a 3.

Invincible Fortress (SD7-EN006)
Gigantes
EARTH / Effect Monster / Level 4 / ATK 1900 / DEF 1300
(Rock / Effect)
This card cannot be Normal Summoned or Set. This card can only be Special Summoned by removing from play 1 EARTH monster in your Graveyard. When this card is destroyed as a result of battle and sent to the Graveyard, destroy all Spell and Trap Cards on the field.
(Common)

Rating: 1 out of 5
Perhaps easier to play than Valkyrion, but Valkyrion just needs what's in your hand or field.

Invincible Fortress (SD7-EN005)
Guardian Sphinx
EARTH / Effect Monster / Level 5 / ATK 1700 / DEF 2400
(Rock / Effect)
Once per turn during your Main Phase, you can flip this card into face-down Defense Position. When this card is Flip Summoned, return all monsters on your opponent's side of the field to the owner's hand.
(Common)

Rating: 3 out of 5
One Tribute (or less) and this guy is ready to undo everything your opponent just played last turn.

Invincible Fortress (SD7-EN004)
Maharaghi
EARTH / Effect Monster / Level 4 / ATK 1200 / DEF 1700
(Rock / Spirit / Effect)
This card cannot be Special Summoned. This card returns to the owner's hand during the End Phase of the turn that this card is Normal Summoned or flipped face-up. If this card is Normal Summoned or flipped face-up, look at 1 card on the top of your Deck during your next Draw Phase (before you draw), and return the card to the top or the bottom of your Deck.
(Common)

Rating: 1 out of 5
You can't have high expectations with this type of effect. It's far less than 50-50 odds.

Invincible Fortress (SD7-EN003)
Giant Rat
EARTH / Effect Monster / Level 4 / ATK 1400 / DEF 1450
(Beast / Effect)
When this card is destroyed as a result of battle and sent to the Graveyard, you can Special Summon 1 EARTH monster with an ATK of 1500 or less in face-up Attack Position from your Deck. Then shuffle your Deck.
(Common)

Rating: 2 out of 5
A risky strategy for Deck that is mostly defensive, but okay elsewhere.

Invincible Fortress (SD7-EN002)
Great Spirit
EARTH / Effect Monster / Level 4 / ATK 500 / DEF 1500
(Rock / Effect)
Once per turn, during your Main Phase, you can flip this card into face-down Defense Position. When this card is Flip Summoned, you can switch the original ATK and DEF of 1 face-up EARTH monster on the field until the end of this turn.
(Common)

Rating: 1 out of 5
Shield & Sword is already included. Don't see why this monster had to be a slower version.

Invincible Fortress (SD7-EN001)
Exxod, Master of The Guard
EARTH / Effect Monster / Level 8 / ATK 0 / DEF 4000
(Rock / Effect)
This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by Tributing 1 monster on your side of the field that includes "sphinx" in its card name. While this card is face-up on the field, each time an EARTH monster is Flip Summoned, inflict 1000 points of damage to your opponent's Life Points.
(Ultra Rare)

Rating: 2 out of 5
Basically 1 Tribute for 4000 DEF, but it's only 1000 damage for EARTH monster Flip Summons.
