Missy + Phyrexian Altar + Dulcet Sirens

Missy

Phyrexian Altar

Dulcet Sirens

How it works

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

This clever loop turns Missy's penchant for reconstruction into a self-sustaining engine by utilizing Phyrexian Altar to feed a creature right back into the graveyard. Whenever you sacrifice Dulcet Sirens to the Altar for mana, Missy steps in to rescue it from the graveyard, returning it directly to the battlefield face down and tapped as a 2/2 Cyberman artifact creature. From there, you simply use the mana you just generated to pay the morph cost printed on Dulcet Sirens, turning it face up and resetting its state so the entire process can begin anew.
