Defiler of Faith + Suture Priest + The Immortal Sun + Whitemane Lion

Defiler of Faith

Suture Priest

The Immortal Sun

Whitemane Lion

How it works

1. Cast Whitemane Lion by paying 0 and 2 life due to Defiler of Faith and The Immortal Sun.
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 charming loop relies on a clever reduction engine where Defiler of Faith and The Immortal Sun work in tandem to completely eliminate the mana cost of Whitemane Lion, allowing you to cast it repeatedly for free by paying life instead. As the Lion continuously enters and leaves the battlefield, its own entry trigger bounces itself right back to your hand while simultaneously triggering Defiler of Faith to flood the board with Soldier tokens. Meanwhile, Suture Priest watches this endless parade of arrivals to pad your life total back up with every single token and Lion that touches down, turning a self-sustaining casting cycle into an endless engine of life and triggers.
