Defiler of Faith + The Wind Crystal + Essence Warden + Whitemane Lion

Defiler of Faith

The Wind Crystal

Essence Warden

Whitemane Lion

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

This looping masterpiece turns a humble cat into an infinite army by engineering a cost-reduction engine that drops Whitemane Lion's mana value all the way down to zero. With The Wind Crystal and Defiler of Faith both trimming down the white requirements—and Defiler of Faith simultaneously rewarding each cast with a fresh 1/1 Soldier token—every iteration keeps your life total stable while flooding the board. As those new tokens enter, Essence Warden notices the commotion and triggers its life-gaining ability, which is doubled by The Wind Crystal's passive life-doubling effect to completely offset the life you paid into the Defiler. Finally, Whitemane Lion's own entry trigger forces it right back to your hand, ready to be cast again for free to sustain the infinite loop of enters-and-leaves-the-battlefield triggers.
