Korvold, Fae-Cursed King + Pitiless Plunderer + Zombie Infestation + Ashnod's Altar

Korvold, Fae-Cursed King

Pitiless Plunderer

Zombie Infestation

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing another creature, adding CC.
2. Korvold's second ability and Pitiless Plunderer trigger.
3. Resolve the Korvold trigger, putting a +1/+1 counter on it and causing you to draw a card.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Activate the Treasure by tapping and sacrificing it, adding one mana of any color.
6. Korvold's second ability triggers, putting a +1/+1 counter on it and causing you to draw a card.
7. Activate Zombie Infestation by discarding two cards, creating a 2/2 Zombie creature token.
8. Repeat.

This engine turns your graveyard and your hand into a self-sustaining loop fueled by Ashnod's Altar, which feeds a sacrifice to generate colorless mana while Pitiless Plunderer quietly turns every departing creature into a Treasure. Those Treasures provide the colored mana and secondary sacrifices needed to keep Korvold, Fae-Cursed King drawing cards and growing massive with every single casualty. Meanwhile, Zombie Infestation acts as the ultimate outlet for the cards Korvold draws, letting you discard excess resources to continuously pump out fresh Zombie tokens to feed right back into the Altar.
