Realm-Scorcher Hellkite + Enduring Renewal + Ashnod's Altar + Genesis Chamber

Realm-Scorcher Hellkite

Enduring Renewal

Ashnod's Altar

Genesis Chamber

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 and Genesis Chamber trigger.
3. Resolve the Realm-Scorcher Hellkite trigger, adding 2.
4. Resolve the Genesis Chamber trigger, creating a 1/1 Myr artifact creature token.
5. Activate Ashnod's Altar by sacrificing Realm-Scorcher Hellkite, adding CC.
6. When Realm-Scorcher Hellkite dies, Enduring Renewal triggers, returning it to your hand from your graveyard.
7. Repeat.

This clever loop centers around Realm-Scorcher Hellkite, which you initially cast with its bargain cost paid so it enters the battlefield generating a mana surplus. As it arrives, Genesis Chamber triggers to supply a fresh Myr artifact creature token while Ashnod's Altar stands ready to instantly sacrifice the Hellkite for colorless mana. Whenever Realm-Scorcher Hellkite hits the graveyard from the battlefield, Enduring Renewal's static ability immediately intercepts the creature and returns it straight to your hand, allowing you to replay it endlessly.
