Defiler of Faith + Soul Warden + The Immortal Sun + Whitemane Lion

Defiler of Faith

Soul Warden

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

This clever loop hinges on the cost-reduction stacking of Defiler of Faith and The Immortal Sun, which together slash the mana cost of Whitemane Lion down to absolute zero—with the Defiler even letting you pay life instead of mana. Once the Lion hits the battlefield, its own entry trigger forces it right back to your hand, while the incidental creature tokens spawned by Defiler of Faith feed into Soul Warden to continuously pad your life total. Because every cycle is self-sustaining and costs zero mana to execute, you can repeat this dance an arbitrary number of times to flood the board and secure massive life gains.
