Thraben Doomsayer + Thornbite Staff + Goblin Bombardment

Thraben Doomsayer

Thornbite Staff

Goblin Bombardment

How it works

1. Activate Thraben Doomsayer by tapping it, creating a 1/1 Human creature token.
2. Activate Goblin Bombardment by sacrificing the Human.
3. When the Human dies, Thraben Doomsayer triggers, untapping Thraben Doomsayer.
4. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
5. Repeat.

This elegant loop harnesses Thraben Doomsayer's ability to constantly manufacture 1/1 white Human creature tokens, which are immediately fed to Goblin Bombardment to deal damage. The secret engine piece holding the whole machine together is Thornbite Staff, equipped to the Doomsayer to grant it a death-triggered untap every time one of those tokens perishes. As long as you can stomach the life total cost, you can repeat this cycle indefinitely to machine-gun down any target with endless death and sacrifice triggers.
