Defiler of Faith + Trostani, Selesnya's Voice + Whitemane Lion + Grand Arbiter Augustin IV

Defiler of Faith

Trostani, Selesnya's Voice

Whitemane Lion

Grand Arbiter Augustin IV

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

This elegant self-sustaining loop relies on a brilliant cost-reduction engine to cast Whitemane Lion for zero mana, utilizing Defiler of Faith alongside Grand Arbiter Augustin IV to completely eliminate its generic and colored mana requirements while paying life instead. Each time the Lion enters the battlefield, its own trigger bounces it right back to your hand while simultaneously fueling Trostani, Selesnya's Voice with a steady stream of life from the tokens generated by Defiler of Faith's cast trigger. By continuously looping the Lion this way, you create an endless parade of creature entries and exits that feed your life total and swarm the board with an unstoppable army of Soldiers.
