Skullbriar, the Walking Grave

Illicit Masquerade

Perigee Beckoner

How it works

1. Cast Illicit Masquerade by paying 3. When it enters, its first ability triggers, putting an impostor counter on Skullbriar.
2. Cast Perigee Beckoner for its warp cost by paying 1.
3. When Perigee Beckoner enters, it triggers, targeting Skullbriar.
4. Activate Goblin Bombardment by sacrificing Perigee Beckoner.
5. Activate Goblin Bombardment by sacrificing Skullbriar.
6. When Skullbriar dies, Illicit Masquerade's second ability and Skullbriar's ability granted to it by Perigee Beckoner trigger.
7. Resolve the Skullbriar trigger, returning it from your graveyard to the battlefield.
8. Resolve the Illicit Masquerade trigger, failing to exile Skullbriar as it has left your graveyard and returning Perigee Beckoner from your graveyard to the battlefield.
9. Resolve the Goblin Bombardment ability from step 5.
10. Repeat from step 3.
