Warren Soultrader + Mm'menon, Uthros Exile + Haliya, Guided by Light

Warren Soultrader

Mm'menon, Uthros Exile

Haliya, Guided by Light

How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing the persist creature.
2. When the persist creature dies, its persist ability triggers, returning the persist creature from your graveyard to the battlefield with a -1/-1 counter on it.
3. When the persist creature enters, Haliya triggers, causing you to gain 1 life.
4. Resolve the Warren Soultrader ability, creating a Treasure token.
5. When the Treasure enters, Mm'menon and Haliya trigger,
6. Resolve the Mm'menon trigger, putting a +1/+1 counter on the persist creature.
7. Resolve the Haliya trigger, causing you to gain 1 life.
8. Repeat.

This clever loop turns a self-sacrificing persist creature into an engine for infinite resources by weaving together death and entry triggers. Warren Soultrader provides the sacrifice outlet you need, trading life and a creature to generate a Treasure token and a death trigger. Meanwhile, Haliya, Guided by Light cushions the life payment by steadily gaining you life whenever permanents enter the battlefield, which also satisfies her condition to draw a card later. Finally, Mm'menon, Uthros Exile acts as the catalyst that neutralizes the persist creature's drawback, placing a +1/+1 counter on it upon arrival to instantly cancel out the -1/+1 counter and keep the cycle going indefinitely.
