Curse of the Deku

Enchant player
Whenever enchanted player discards a card, you
may search your library for a card of the same
type and put it into your graveyard. Then shuffle.
Snatch {4}{b}{g} (You may cast this spell for its
snatch cost. If you do, change its text by replacing all
instances of "your" with "target opponent's." If there
are multiple instances of this change, they must all
have the same target.)
