Defiler of Faith + The Wind Crystal + Whitemane Lion + Bogwater Lumaret

Defiler of Faith

The Wind Crystal

Whitemane Lion

Bogwater Lumaret

How it works

1. Cast Whitemane Lion by paying 0 and 2 life due to Defiler of Faith and The Wind Crystal.
2. Defiler of Faith triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters, Bogwater Lumaret triggers, causing you to gain life.
4. Resolve Whitemane Lion. When it enters, it and Bogwater Lumaret trigger.
5. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
6. Resolve the Bogwater Lumaret trigger, causing you to gain life.
7. Repeat.

This loop turns a simple lion into a self-sustaining engine by exploiting clever cost reduction and life manipulation. With Defiler of Faith and The Wind Crystal both on the battlefield, the white mana cost of Whitemane Lion is entirely erased, allowing you to cast it for free by just paying 2 life instead. Every time the Lion enters the battlefield, it triggers its own ability to bounce itself back to your hand, while Bogwater Lumaret provides a steady stream of life whenever any creature arrives. Meanwhile, The Wind Crystal doubles your life gain and Defiler of Faith rewards your spellcasting by spawning a 1/1 white Soldier creature token with every iteration, letting you loop the process endlessly to flood the board and gain infinite life.
