Wheel of Misfortune + Barbed Servitor + With Great Power . . .

Wheel of Misfortune

Barbed Servitor

With Great Power . . .

How it works

1. Cast Wheel of Misfortune by paying 2, choosing an arbitrarily large number and having Wheel of Misfortune deal that much damage to Barbed Servitor instead of you due to With Great Power... if you chose the largest number.
2. Barbed Servitor triggers, causing an opponent to lose life equal to the damage dealt.
