Defiler of Faith + Suture Priest + Kor Skyfisher + Grand Arbiter Augustin IV

Defiler of Faith

Suture Priest

Kor Skyfisher

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

This ingenious loop relies on a brilliant alignment of cost reducers and life payments to cast Kor Skyfisher entirely for free, as Grand Arbiter Augustin IV and Defiler of Faith work together to completely eliminate its mana value while the latter lets you trade 2 life instead. Once the Skyfisher hits the battlefield, its own entry trigger forces you to bounce it right back to your hand so you can cast it all over again. Meanwhile, Defiler of Faith's passive ability rewards each casting by flooding the board with 1/1 Soldier tokens, which in turn trigger Suture Priest to endlessly pad your life total on every single iteration.
