Defiler of Faith + Suture Priest + Helm of Awakening + Whitemane Lion

Defiler of Faith

Suture Priest

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

This clever loop turns a modest feline into an infinite-value engine by manipulating the stack and cost reductions. With Helm of Awakening making artifact and creature spells cheaper, Defiler of Faith steps in to completely wipe out the remaining generic and white mana cost of Whitemane Lion by letting you trade life instead, allowing you to cast it for free. As the Lion repeatedly enters and bounces itself back to your hand, Suture Priest capitalizes on every single entry by padding your life total. Meanwhile, every cast of the Lion triggers Defiler of Faith to flood the board with an endless army of Soldier tokens, which Suture Priest duly rewards with even more life.
