Defiler of Faith + Helm of Awakening + Whitemane Lion + Bogwater Lumaret

Defiler of Faith

Helm of Awakening

Whitemane Lion

Bogwater Lumaret

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, 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 clever loop relies on a cost-reduction engine to cast and reset a self-bouncing creature entirely for free. With Helm of Awakening and Defiler of Faith both chipping away at mana costs, Whitemane Lion becomes entirely free to cast by trading a small amount of life instead of mana. Every time the Lion drops, Defiler of Faith rewards your white permanent spell with a fresh 1/1 Soldier creature token. Those entering tokens immediately trigger Bogwater Lumaret to pad your life total, while the Lion's own entry trigger bounces itself right back to your hand to start the cycle anew.
