Defiler of Faith + Trostani, Selesnya's Voice + The Immortal Sun + Kor Skyfisher

Defiler of Faith

Trostani, Selesnya's Voice

The Immortal Sun

Kor Skyfisher

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

This clever loop turns the humble Kor Skyfisher into a self-sustaining engine by combining cost reducers and token generators. With The Immortal Sun and Defiler of Faith both chipping away at the casting cost, you can cast the Skyfisher for free by paying 2 life, which in turn triggers Defiler of Faith to spawn a 1/1 Soldier token. That token's entry prompts Trostani, Selesnya's Voice to reward you with lifegain, while the Skyfisher's own entry forces you to bounce a permanent—neatly targeting itself to reset the loop.
