Defiler of Faith + Leyline of Vitality + The Immortal Sun + Whitemane Lion

Defiler of Faith

Leyline of Vitality

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

This elegant loop transforms the humble Whitemane Lion into an endless engine for tokens and life by reducing its mana cost to zero. With The Immortal Sun shaving off {1} and Defiler of Faith trading 2 life for the remaining white mana requirement, you can repeatedly cast the Lion for free; its own triggered ability then returns it safely to your hand to start the cycle anew. Meanwhile, Defiler of Faith leverages each casting to flood the board with 1/1 Soldier tokens, and Leyline of Vitality rewards every single creature entry and token arrival with a steady stream of life.
