Defiler of Faith + Healer of the Pride + Helm of Awakening + Whitemane Lion

Defiler of Faith

Healer of the Pride

Helm of Awakening

Whitemane Lion

How it works

1. Cast Whitemane Lion 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, Healer of the Pride triggers, causing you to gain life.
4. Resolve Whitemane Lion. When it enters, it and Healer of the Pride trigger.
5. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
6. Resolve the Healer of the Pride trigger, causing you to gain life.
7. Repeat.

This loop sets up an infinitely repeating engine that can be executed at instant speed, fueled by cost-reducers and self-bouncing mechanics. With Helm of Awakening lowering generic costs and Defiler of Faith discounting the colored mana requirement while paying life, you can cast Whitemane Lion for zero mana and repeat the process endlessly. Every iteration sees the Lion enter the battlefield to bounce itself back to your hand, triggering Healer of the Pride for a stream of life while Defiler of Faith simultaneously floods the board with an endless army of 1/1 Soldier tokens.
