Defiler of Faith + Pearl Medallion + Auriok Champion + Kor Skyfisher

Defiler of Faith

Pearl Medallion

Auriok Champion

Kor Skyfisher

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and Pearl Medallion.
2. Defiler of Faith triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters, Auriok Champion triggers, causing you to gain life.
4. Resolve Kor Skyfisher. When it enters, it and Auriok Champion trigger.
5. Resolve the Kor Skyfisher trigger, returning it from the battlefield to your hand.
6. Resolve the Auriok Champion trigger, causing you to gain life.
7. Repeat.

This loop relies on a brilliant cost-reduction engine to cast Kor Skyfisher for free, leveraging Pearl Medallion alongside Defiler of Faith to completely eliminate the spell's mana cost while paying 2 life instead. Every time Kor Skyfisher hits the battlefield, its enter-the-battlefield trigger forces you to bounce it right back to your hand, creating an endless cycle that fuels Defiler of Faith's static ability to churn out 1/1 Soldier creature tokens. Those entering tokens simultaneously trigger Auriok Champion, whose own passive protection and lifegain abilities turn the entire process into an infinite stream of life and triggers.
