Doomed Necromancer

Hammer of Purphoros

How it works

1. Activate Ashnod's Altar by sacrificing Eternal Witness, adding CC.
2. When Eternal Witness dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
3. Activate the Treasure by tapping and sacrificing it, adding .
4. Activate Doomed Necromancer by paying , tapping it and sacrificing it.
5. When Doomed Necromancer dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
6. Resolve the Doomed Necromancer ability, returning Eternal Witness from your graveyard to the battlefield.
7. When Eternal Witness enters the battlefield, it triggers, returning Doomed Necromancer from your graveyard to your hand.
8. Activate a Treasure by tapping and sacrificing it, adding .

10. Repeat.

This loop is a masterclass in recycling resources, transforming the sacrifice of your own creatures into a self-sustaining engine. Ashnod's Altar provides the initial raw mana and a sacrifice outlet, while Pitiless Plunderer quietly watches the graveyard queue to fund your black mana needs with every fallen ally. Doomed Necromancer acts as the resurrection engine to constantly pull Eternal Witness out of the yard, and Eternal Witness in turn returns Doomed Necromancer right back to your hand to keep the cycle going. Meanwhile, Hammer of Purphoros sits quietly on the board, ensuring that any hasty tokens you might manifest along the way can act immediately, though the true genius here lies in how smoothly the death and recursion pieces lock into an infinite loop.
