Yahenni, Undying Partisan + Railway Brawler

Yahenni, Undying Partisan

Railway Brawler

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, Railway Brawler triggers, putting a number of +1/+1 counters on the persist creature.
4. Resolve the Yahenni ability.
5. Repeat
