Gehrman, First Hunter

First strike, menace, haste

During your turn, whenever one or more creatures
an opponent controls dies, create a Blood token and
put two +1/+1 counters on Gehrman.

Sacrifice three Blood tokens: Return a card with
Madness from your graveyard to your hand.
Activate only as a sorcery and only once each turn.
