Goblin Bombardment

How it works

1. Activate Adarkar Valkyrie by tapping it, targeting another nontoken creature you control.
2. Activate Goblin Bombardment by sacrificing the creature targeted in step 1.
3. When the creature dies, Adarkar Valkyrie triggers twice.
4. Resolve the first trigger, untapping Adarkar Valkyrie.
5. Resolve the second trigger, returning the sacrificed creature from your graveyard to the battlefield.
6. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
7. Repeat.
