Bontu's Monument + Pitiless Plunderer + Oathsworn Vampire + Goblin Bombardment

Bontu's Monument

Pitiless Plunderer

Oathsworn Vampire

Goblin Bombardment

How it works

1. Cast Oathsworn Vampire either from your hand or from your graveyard by paying due to Bontu's Monument.
2. Bontu's Monument triggers, causing each opponent to lose 1 life and you to gain 1 life.
3. Activate Goblin Bombardment by sacrificing Oathsworn Vampire.
4. When Oathsworn Vampire dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
5. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Repeat.

This loop creates a self-sustaining engine of sacrifice and resurrection, fueled by the relentless pressure of Oathsworn Vampire returning from the graveyard. Because Bontu's Monument discounts its black casting cost and rewards you with life whenever you cast it, you easily satisfy the vampire's resurrection condition while draining your opponents. Once the vampire is on the battlefield, Goblin Bombardment provides the immediate outlet to send it to the graveyard, which in turn triggers Pitiless Plunderer to forge a Treasure token. Sacrificing that Treasure for mana pays the reduced cost to cast Oathsworn Vampire again, letting you repeat the cycle indefinitely for infinite damage and life swings.
