• By using "Revoke Fusion", you can send a Hero Fusion Monster with high ATK to your graveyard, without going through natural means. This way, you can decrease the selected monster's ATK even more.
  • Use this monster while you have "Elemental Hero The Shining" on the field, as "Koga" can boost The Shining's ATK.
  • By using "Ojama Trio" or "Nightmare Archfiends", you can boost Koga's ATK by 1500.
