Wormfang Manta + Karador, Ghost Chieftain + Torpor Orb + Phyrexian Altar

Wormfang Manta

Karador, Ghost Chieftain

Torpor Orb

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Wormfang Manta, adding .
2. When Wormfang Manta dies, its second ability triggers, causing you to take an extra turn after this one.
3. Cast Wormfang Manta by paying 5.
4. Wormfang Manta's first ability does not trigger when it enters the battlefield due to Torpor Orb.
5. Repeat each turn.

Torpor Orb is the clever enabler here, silently shutting down Wormfang Manta's enters-the-battlefield penalty so you never have to skip a turn. This lets you freely feed Wormfang Manta to Phyrexian Altar to generate mana and trigger its leaves-the-battlefield ability, securing an extra turn every single cycle. From there, Karador, Ghost Chieftain steps in to bypass normal card-drawing constraints by letting you recast that exact same Wormfang Manta directly from your graveyard once per turn, locking down infinite turns with eerie efficiency.
