Kazark, Gore Tyrant

At the beginning of your upkeep, you loose half
your life, rounded up.
Sacrifice a creature: Until the end of turn, target
creature you control gets +X/+X, where X is the
sacrificed creature's toughness.
Each time a nontoken creature dies, choose one :
• Gain life equal to that creature's toughness.
• Create a 3/3 black and red Horror
creature token.
