Emergency Graft

When you cast Emergency Graft, choose a
creature on the battlefield.
Creatures you control gain Hexproof and get
+0/+X until the end of turn, where X is equal
to the chosen Creature's Toughness.
To survive the Slough its denizens shed their
humanity, some became mindless and monstrous,
others like the Sage and her Gafter's surpassed their
flesh.
