Defiler of Faith + Whitemane Lion + Grand Arbiter Augustin IV + Case of the Uneaten Feast

Defiler of Faith

Whitemane Lion

Grand Arbiter Augustin IV

Case of the Uneaten Feast

How it works

1. Cast Whitemane Lion by paying 0 and 2 life due to Defiler of Faith and Grand Arbiter Augustin IV.
2. Defiler of Faith triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters, Case of the Uneaten Feast triggers, causing you to gain life.
4. Resolve Whitemane Lion. When it enters, it and Case of the Uneaten Feast trigger.
5. Resolve the Whitemane Lion trigger, returning it from the battlefield to your hand.
6. Resolve the Case of the Uneaten Feast trigger, causing you to gain life.
7. Repeat.

This loop turns the noble cat adventurer into a self-sustaining engine of life and troops, starting with Grand Arbiter Augustin IV reducing the cost of white spells so that Defiler of Faith can turn the remaining mana requirement into mere life payments. Because Defiler of Faith also triggers off casting a white permanent to spawn a 1/1 Soldier token, every cycle feeds Case of the Uneaten Feast to continuously trigger life gain. This life gain keeps your health safe while Whitemane Lion bounces itself back to your hand upon entering the battlefield, letting you recast it for free endlessly.
