Missy + Phyrexian Altar + Grim Haruspex

Missy

Phyrexian Altar

Grim Haruspex

How it works

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

This clever loop centers around Missy, whose wicked necromancy ensures that whenever another nonartifact creature dies, it immediately creeps back onto the battlefield under your control as a face-down 2/2 Cyberman artifact creature. By sacrificing Grim Haruspex to Phyrexian Altar, you generate the black mana needed to turn Grim Haruspex face up using its morph ability. As Grim Haruspex dies, its own static trigger and Missy's replacement effect work in tandem to fuel infinite sacrifices and death triggers, creating a perpetual motion machine of recycling doom.
