Defiler of Faith + Trostani, Selesnya's Voice + Helm of Awakening + Whitemane Lion

Defiler of Faith

Trostani, Selesnya's Voice

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

This brilliant loop turns the unassuming feline Whitemane Lion into a self-sustaining engine of life and troops. Thanks to the cost-reducing magic of both Defiler of Faith and Helm of Awakening, the Lion can be cast for free by paying life, which immediately triggers the Defiler to spawn a 1/1 Soldier token. That token's arrival delights Trostani, Selesnya's Voice, padding your life total every single iteration. Finally, when the Whitemane Lion hits the battlefield, its own entry trigger forces it right back to your hand, allowing you to reset and repeat the entire cycle endlessly.
