Realm-Scorcher Hellkite + Enduring Renewal + Ashnod's Altar + Requiem Angel

Realm-Scorcher Hellkite

Enduring Renewal

Ashnod's Altar

Requiem Angel

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, Requiem Angel and Enduring Renewal trigger.
5. Resolve the Requiem Angel trigger, creating a 1/1 Spirit creature token.
6. Resolve the Enduring Renewal trigger, returning it to your hand from your graveyard.
7. Repeat.

This elegant engine turns the bargain-fueled entry of Realm-Scorcher Hellkite into an endless loop by leaning on Enduring Renewal to continually bounce the dragon straight back to your hand whenever it hits the graveyard. Meanwhile, Ashnod's Altar provides the sacrifice outlet needed to loop the Hellkite while funding its re-casting costs with endless colorless mana. To keep the machinery running, Requiem Angel triggers off the steady stream of creature deaths to spawn Spirit tokens, offering a convenient permanent type to satisfy future Bargain costs whenever you need to restart the cycle.
