Corpse Cur + Molten Echoes + Ashnod's Altar

Corpse Cur

Molten Echoes

Ashnod's Altar

How it works

1. Cast Corpse Cur.
2. When Corpse Cur ETBs, Corpse Cur and Molten Echoes trigger.
3. Allow the Corpse Cur trigger to fizzle.
4. Activate Ashnod's Altar by sacrificing Corpse Cur, adding CC.
5. Resolve the Molten Echoes trigger, creating a token copy of Corpse Cur.
6. The token copy of Corpse Cur triggers on ETB, returning the original Corpse Cur to your hand.
7. Activate Ashnod's Altar by sacrificing the token copy of Corpse Cur, adding CC Repeat.
