Monsters your opponent controls lose 100 ATK/DEF for each "Mayakashi" monster with a different name in your GY. You can only use 1 of the following effects of "Mayakashi Winter" per turn, and only once that turn. ● Send this card and 1 "Mayakashi" monster you control to the GY; draw 1 card. ● Banish this card and 1 Zombie monster from your GY, then target 1 "Mayakashi" monster in your GY; Special Summon it.
