Warren Soultrader + Mm'menon, Uthros Exile + Soul's Attendant

Warren Soultrader

Mm'menon, Uthros Exile

Soul's Attendant

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, Soul's Attendant triggers, causing you to gain 1 life.
4. Resolve the Warren Soultrader ability, creating a Treasure token.
5. When the Treasure enters, Mm'menon triggers, putting a +1/+1 counter on the persist creature.
6. Repeat.

This loop turns the life-paying sacrifice outlet Warren Soultrader into a self-sustaining engine by relying on a persist creature to constantly feed it. Every time you sacrifice that creature, Soul's Attendant cushions the life payment with its triggered lifegain, ensuring you never run out of life. Meanwhile, the resulting Treasure token enters the battlefield to trigger Mm'menon, Uthros Exile, whose ability places a +1/+1 counter that cancels out the creature's -1/-1 counter so the persist cycle can repeat indefinitely.
