Yahenni, Undying Partisan + Support Mission

Yahenni, Undying Partisan

Support Mission

How it works

1. Activate Yahenni by sacrificing the persist creature.
2. When the persist creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When the persist creature enters, Support Mission triggers, putting a +1/+1 counter on that creature.
4. Resolve the Yahenni ability.
5. Repeat
