Whenever Jagged Poppet is dealt damage, discard that many cards.

Hellbent — Whenever Jagged Poppet deals combat damage to a player, if you have no cards in hand, that player discards cards equal to the damage.

Whenever you cast an instant or sorcery spell, create a 2/2 black Zombie creature token with decayed. (It can't block. When it attacks, sacrifice it at end of combat.)

At the beginning of your upkeep, if you control three or more creature tokens, you may transform Poppet Stitcher.
