Nihil, Cursed Prince

Transforms from Silverfang, Acolyte of Ul
Flying, Wither
At the start of your upkeep, flip a coin and declare heads or tails. If you win the flip, Nihil gains +2/+2 and deals 3 damage to any target. If you lose, Nihil deals 5 damage to you. If the coin is neither heads or tails, Nihil transforms back.
