Missy + Phyrexian Altar + Riptide Pilferer

Missy

Phyrexian Altar

Riptide Pilferer

How it works

1. Activate Phyrexian Altar by sacrificing Riptide Pilferer, adding .
2. When Riptide Pilferer dies, Missy's first ability triggers, returning Riptide Pilferer from your graveyard to the battlefield face down as a 2/2 Cyberman artifact creature.
3. Activate Riptide Pilferer's morph ability by paying , turning it face up.
4. Repeat.

This clever little loop uses Phyrexian Altar to turn your own creatures into fuel, feeding the mana right back into the engine while triggering Missy's watchful eye. Whenever Riptide Pilferer hits the graveyard from this sacrifice, Missy immediately brings it back to the battlefield face down as a 2/2 Cyberman artifact creature. From there, you simply use the mana you generated to pay Riptide Pilferer's morph cost, turning it face up so it's ready to be sacrificed to the Altar all over again.
