Defiler of Faith

Verdant Sun's Avatar

Kor Skyfisher

Grand Arbiter Augustin IV

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and Grand Arbiter Augustin IV.
2. Defiler of Faith triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters, Verdant Sun's Avatar triggers, causing you to gain life.
4. Resolve Kor Skyfisher. When it enters, it and Verdant Sun's Avatar trigger.
5. Resolve the Kor Skyfisher trigger, returning it from the battlefield to your hand.
6. Resolve the Verdant Sun's Avatar trigger, causing you to gain life.
7. Repeat.

This ingenious loop turns a simple flier into a self-sustaining engine by completely removing the mana cost of Kor Skyfisher. With Grand Arbiter Augustin IV shaving off {1} and Defiler of Faith discounting the remaining white mana in exchange for 2 life, you can repeatedly cast the Skyfisher for free. Every time the Skyfisher enters the battlefield, its own drawback actually helps your cause by bouncing itself back to your hand, while Defiler of Faith capitalizes on the cast to pump out a 1/1 Soldier token. Finally, Verdant Sun's Avatar watches over the chaos, easily healing back the life you spent as both the tokens and the Skyfisher continually enter the battlefield.
