Scar-Shriven Mystic

Scar-Shriven Mystic has hexproof as long as a player sacrificed a creature this turn.

At the beginning of each player's upkeep, choose target creature that player controls. Its controller loses life equal to its mana value unless they sacrifice it.

Whenever an opponent sacrifices a creature, put your choice of up to one deathtouch counter, lifelink counter or +1/+1 counter on target creature you control.
