Defiler of Faith + The Immortal Sun + Kor Skyfisher + Angelic Chorus

Defiler of Faith

The Immortal Sun

Kor Skyfisher

Angelic Chorus

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and The Immortal Sun.
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 engine relies on cost reduction to turn Kor Skyfisher into a free self-bouncing loop, fueled by The Immortal Sun and Defiler of Faith reducing its mana cost down to zero while Defiler of Faith lets you pay life instead of white mana. Every time Kor Skyfisher enters the battlefield, Angelic Chorus rewards your growing board with life, while Defiler of Faith triggers concurrently to flood the board with 1/1 Soldier creature tokens.
