Defiler of Faith + Oketra's Monument + Kor Skyfisher + Hinterland Sanctifier

Defiler of Faith

Oketra's Monument

Kor Skyfisher

Hinterland Sanctifier

How it works

1. Cast Kor Skyfisher by paying 0 and 2 life due to Defiler of Faith and Oketra's Monument.
2. Defiler of Faith and Oketra's Monument trigger.
3. Resolve the Defiler of Faith trigger, creating a 1/1 Soldier creature token.
4. When the Soldier enters, Hinterland Sanctifier triggers, causing you to gain life.
5. Resolve the Oketra's Monument trigger, creating a 1/1 Warrior creature token.
6. When the Warrior enters, Hinterland Sanctifier triggers, causing you to gain life.
7. Resolve Kor Skyfisher. When it enters, it and Hinterland Sanctifier trigger.
8. Resolve the Kor Skyfisher trigger, returning it from the battlefield to your hand.
9. Resolve the Hinterland Sanctifier trigger, causing you to gain life.
10. Repeat.

This loop transforms Kor Skyfisher into a free, self-returning engine by stacking massive cost reductions from both Defiler of Faith and Oketra's Monument. Because those combined discounts reduce the white creature's mana cost down to zero, you can repeatedly cast it while paying life instead of mana to satisfy Defiler of Faith's alternative cost. Every time the Kor Skyfisher enters and bounces itself back to your hand, both artifact and enchantment token generators flood the board with creatures, which in turn trigger Hinterland Sanctifier to continuously replenish your life total.
