Defiler of Faith + The Wind Crystal + Verdant Sun's Avatar + Kor Skyfisher

Defiler of Faith

The Wind Crystal

Verdant Sun's Avatar

Kor Skyfisher

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and The Wind Crystal.
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 clever loop turns Kor Skyfisher into a self-returning engine by leveraging the passive cost reductions of both Defiler of Faith and The Wind Crystal to drop its mana value to zero. Because Defiler of Faith rewards your white permanent spells with a 1/1 Soldier token on cast, every iteration floods the board while triggering Verdant Sun's Avatar to double your life totals thanks to The Wind Crystal's life-doubling replacement effect. Finally, Kor Skyfisher's own entry trigger forces you to bounce a permanent, which effortlessly scoops itself back to your hand so you can repeat the entire process indefinitely.
