Defiler of Faith + Kor Skyfisher + Angelic Chorus + Grand Arbiter Augustin IV

Defiler of Faith

Kor Skyfisher

Angelic Chorus

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, Angelic Chorus triggers, causing you to gain life.
4. Resolve Kor Skyfisher. When it enters, it and Angelic Chorus trigger.
5. Resolve the Kor Skyfisher trigger, returning it from the battlefield to your hand.
6. Resolve the Angelic Chorus trigger, causing you to gain life.
7. Repeat.

This elegant loop relies on Grand Arbiter Augustin IV and Defiler of Faith working together to completely eliminate the mana cost of Kor Skyfisher, allowing you to cast it for free by just paying life. Every time the Skyfisher enters and bounces itself back to your hand, Defiler of Faith triggers to produce a 1/1 white Soldier token. That token's entry then triggers Angelic Chorus, restoring your life total and completely offsetting the life paid to the Defiler's cost reduction.
