Azamina Determination (ROTA-EN073) [Rage of the Abyss]

Reveal 1 "Azamina" Fusion Monster in your Extra Deck, and for every 4 Levels it has (round down), shuffle 1 "Sinful Spoils" card from your GY and/or banishment into the Deck, then Special Summon the revealed monster. (This is treated as a Fusion Summon.) You can banish this card from your GY, then target 1 "Sinful Spoils" Spell/Trap in your GY; Set it, but it cannot be activated this turn. You can only use 1 "Azamina Determination" effect per turn, and only once that turn.
