Volcano Hellion

Scion of Draco

Painter's Servant

How it works

1. Cast Volcano Hellion by paying 2.
2. Volcano Hellion enters the battlefield, dealing an arbitrarily large amount of damage to you and target creature, and causing you to gain life equal to the total amount of damage done this way.
