Cardian Hanafuda Game
Spell - Field
If this card is sent to the graveyard by the effect of a "Flower Cardian" monster: activate this card from your graveyard. Once per turn, during your main phase: you can take 1 "Flower Cardian" monster from your deck or graveyard and place it on top of your deck. Once per turn, when a "Flower Cardian" monster is summoned to your field: you can draw 1 card and reveal it. If the card is a "Flower Cardian" monster, you can normal summon a "Flower Cardian" monster in addition to your normal summon this turn. "Cardian" monsters you control cannot be destroyed by battle.
