Must be Special Summoned with "Mask Change" and cannot be Special Summoned by other ways. This card gains 500 ATK for each monster your opponent controls. Once per turn, during either player's turn: You can banish 1 "HERO" monster from your Graveyard, then target 1 face-up monster on the field; that target loses ATK equal to the ATK of the monster banished to activate this effect, until the end of this turn.

  • Self ATK boost.
  • Can debuff an enemy monster.


  • Specific summoning condition.
  • Requires you to banish a HERO monster.



Target a LIGHT attribute HERO monster with Masked Change to Special Summon Koga. Elemental HERO Neos Alius is a good target, and Elemental HERO Voltic can also be run in the deck to recover banished monsters.

Form Change can let you tag out a level-8 HERO Fusion monster into Koga. This includes many good monsters such as Elemental HERO Great Tornado and Vision HERO Adoration.

Both Change cards are Quick-Play Spells, allowing you to also use them during your opponent’s turn and during your Battle Phase. During your Battle Phase, you can battle with the monster already on your field then Change into Koga, good to combo with Masked HERO Anki who searches Change cards.

Elemental HERO Blazeman

Use Elemental HERO Blazeman’s effect to send Elemental HERO Neos to the graveyard and copy his attribute and set up a powerful HERO in your graveyard. Target Blazeman with Mask Change to make Koga and banish Neos to debuff an opponent’s monster.

Banish Zone Setup

Banishing monsters for Koga’s effect cost lets you power up an Elemental HERO The Shining you control. Parallel World Fusion can use your banished monsters as fusion material.

Favorite Hero

Can be equipped to any high-level HERO to give them a significant ATK boost and protection from targeting effects. The Field Spell search allows you to activate something like Necrovalley from your deck. This will prevent you from debuffing enemy monsters with Koga but with the ATK boost of Favorite Hero, Koga would be especially hard to run over.


Use Ojama Go! or Ojama Overflow to fill your opponent's field with tokens and bring Koga's ATK to 4000.

The second best HERO. The best HERO is not released yet, and it should have been. Prisma OR Blazeman is required for its mask change.

They already released Bubbleman which is the best HERO
Does "Once per turn, during either player's turn" means this effect is quick play?

The spell speed is not mentionned. Can it be used during damage step or calculation.

Yes, it means the effect is a Quick effect.

It should list it as a quick effect then. Due to how other cards use the same wording but can only be used during Main 1, it's easily assumed that Koga can only proc during Main 1.

No, if it's usable only during your MP1 it would only say "Once per turn".

Not "Once per turn, during either player's turn".

"During either player's turn" is the old term for "(Quick effect)" in card texts.
The artwork is superb
here comes another broken one

Koga isn't that broken, actually.

Its OTK capability isn't on the same level as Anki, and its not a walking strong disruption/utility like Dark Law and Divine Wind.

Best target would be elemental hero neos alius, Sparkman, flash and voltic are 🔥ty alternatives or using Form change on anki or Dian would also be possible
Resemble to which Kamen Rider?
