Defiler of Faith + Soul Warden + Helm of Awakening + Kor Skyfisher

Defiler of Faith

Soul Warden

Helm of Awakening

Kor Skyfisher

How it works

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

This clever loop uses the cost-reduction power of Helm of Awakening and the life-payment discount of Defiler of Faith to cast Kor Skyfisher for a net mana cost of zero, turning your white creature spells into a self-sustaining engine. Every time the Skyfisher hits the board, it bounces itself back to your hand with its mandatory entry trigger, while Defiler of Faith simultaneously floods the battlefield with fresh 1/1 Soldier creature tokens. Those tokens arriving home then wake up Soul Warden to continuously pad your life total, easily offsetting the 2 life you spent to fuel the Defiler's discount and keeping your loop going indefinitely.
