Realm-Scorcher Hellkite + Enduring Renewal + Ashnod's Altar + Pitiless Plunderer

Realm-Scorcher Hellkite

Enduring Renewal

Ashnod's Altar

Pitiless Plunderer

How it works

1. Cast Realm-Scorcher Hellkite by paying 4 and sacrificing an additional artifact, enchantment or token.
2. When Realm-Scorcher Hellkite enters the battlefield, it triggers, adding 2.
3. Activate Ashnod's Altar by sacrificing Realm-Scorcher Hellkite, adding CC.
4. When Realm-Scorcher Hellkite dies, Pitiless Plunderer and Enduring Renewal trigger.
5. Resolve the Pitiless Plunderer trigger, creating a Treasure artifact token.
6. Resolve the Enduring Renewal trigger, returning it to your hand from your graveyard.
7. Repeat.

This loop is masterminded by Enduring Renewal, which redirects any creature dying on your battlefield straight back to your hand rather than letting it linger in the graveyard. When you cast Realm-Scorcher Hellkite with its bargain cost paid, its entry ability immediately funds part of its own casting requirements, setting the stage to feed it into Ashnod's Altar. As the Hellkite hits the altar and is sacrificed for colorless mana, Pitiless Plunderer quietly watches from the sidelines to generate a Treasure token off the death, ensuring you have the exact resources needed to replay the dragon over and over.
