MTG Combo: Pariah + Stuffy Doll + Volcano Hellion
This is an interesting infinite damage combo that has only one use.
Pariah onto Stuffy Doll, meaning that any damage you take is redirected to your opponent. You play Volcano Hellion and choose some arbitrarily large number, to you and to your Stuffy Doll that has Pariah attached to it. This deals twice the amount of damage you choose for Volcano Hellion onto your opponent, once.
