Defiler of Faith + Helm of Awakening + Whitemane Lion + Hinterland Sanctifier

Defiler of Faith

Helm of Awakening

Whitemane Lion

Hinterland Sanctifier

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, Hinterland Sanctifier triggers, causing you to gain life.
4. Resolve Whitemane Lion. When it enters, it and Hinterland Sanctifier trigger.
5. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
6. Resolve the Hinterland Sanctifier trigger, causing you to gain life.
7. Repeat.

This clever loop turns your white creatures into a self-sustaining engine by stacking cost reductions until your spells are practically free. With Helm of Awakening and Defiler of Faith both chipping away at the mana requirements, you can repeatedly cast Whitemane Lion for zero mana while using its own entry trigger to bounce itself back to your hand. Every single iteration of casting the Lion fuels Defiler of Faith to flood the board with 1/1 Soldier tokens, which in turn triggers Hinterland Sanctifier to continuously buffer your life total against the life you paid for the Defiler's cost.
