Nevinyrral, Urborg Tyrant + Rooftop Storm + Cloudstone Curio

Nevinyrral, Urborg Tyrant

Rooftop Storm

Cloudstone Curio

How it works

1. Cast Nevinyrral either from your hand or the command zone by paying 0 plus commander tax, if applicable.
2. Nevinyrral enters the battlefield, triggering itself and Cloudstone Curio.
3. Resolve the Cloudstone Curio trigger, choosing to return nothing to your hand from the battlefield.
4. Resolve the Nevinyrral trigger, creating a tapped 2/2 Zombie creature token for each creature that has died this turn.
5. Each Zombie enters the battlefield, triggering Cloudstone Curio that many times.
6. Resolve the first Cloudstone Curio trigger, returning Nevinyrral to your hand from the battlefield.
7. Resolve each remaining Cloudstone Curio trigger, choosing to return nothing to your hand from the battlefield.
8. Repeat.
