Defiler of Faith + Distinguished Conjurer + Kor Skyfisher + Grand Arbiter Augustin IV

Defiler of Faith

Distinguished Conjurer

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

This engine achieves immortality and an endless army by turning Kor Skyfisher into a free, self-returning loop. Grand Arbiter Augustin IV reduces the creature's generic mana cost, while Defiler of Faith allows you to pay 2 life instead of the remaining white mana, meaning you can cast Kor Skyfisher for zero mana. Each time it enters the battlefield, its own trigger forces you back to your hand, but Defiler of Faith simultaneously replaces the cast with a fresh 1/1 Soldier creature token. That token's arrival triggers Distinguished Conjurer to pad your life total back up, sustaining the life payment needed to keep the cycle spinning infinitely.
