Serra the Benevolent + Coalhauler Swine + Volcano Hellion

Serra the Benevolent

Coalhauler Swine

Volcano Hellion

How it works

1. Cast Volcano Hellion by paying 2.
2. Volcano Hellion enters the battlefield, triggering itself, dealing an arbitrarily large amount of damage to Coalhauler Swine and to you, which does not reduce your life total below 1 due to Serra the Benevolent's emblem.
3. Coalhauler Swine triggers, dealing an equal amount of damage to each player, which again does not reduce your life total below 1.
