This clever loop transforms a humble graveyard interaction into a self-sustaining engine fueled by Ashnod's Altar, which happily turns your sacrificed creatures into raw colorless mana. The secret lies in pairing Iridescent Drake with False Demise; when the Drake enters the battlefield, its trigger plucks the Aura right back out of the graveyard and attaches it to the Drake once more. Because False Demise watches over the enchanted creature and resurrects it whenever it dies, you can endlessly sacrifice the Drake to the Altar, trigger the resurrection, and loop the enchantment right back onto its host to repeat the cycle indefinitely.
