This ingenious loop lets you seize infinite turns by weaponizing Wormfang Manta's leaving-the-battlefield trigger while completely dodging its downside. Normally, Torpor Orb's static ability suppresses the Manta's entry trigger, meaning you skip your next turn for nothing while still guaranteeing you'll take an extra turn whenever it eventually leaves. By feeding the creature to Ashnod's Altar, you generate the colorless mana needed to help fund your next loop and send the Manta straight to your graveyard. From there, Karador, Ghost Chieftain's passive ability lets you recast the Wormfang Manta right back onto the battlefield from your graveyard once each turn, repeating the sacrifice-and-cast cycle to chain an endless series of extra turns.
