Defiler of Faith + Guide of Souls + Helm of Awakening + Whitemane Lion

Defiler of Faith

Guide of Souls

Helm of Awakening

Whitemane Lion

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

This clever engine harnesses cost-reducers to loop a single creature entirely for free, turning life into an overwhelming army. With Helm of Awakening and Defiler of Faith both chipping away at generic and white mana requirements, you can repeatedly cast Whitemane Lion for zero mana by paying 2 life to the Defiler's static reduction ability. Every single time the Lion enters the battlefield, its own trigger forces it right back to your hand while Defiler of Faith spawns a fresh 1/1 Soldier token. That token's arrival—alongside the Lion's—pumps your energy reserves and life total through Guide of Souls, giving you a compounding cascade of entering-the-battlefield triggers, tokens, and energy.
