Missy + Phyrexian Altar + Coral Trickster

Missy

Phyrexian Altar

Coral Trickster

How it works

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

This brilliant loop sets up an endless cycle of sacrifice and rebirth by leveraging Missy to intercept your creatures as they perish. When you sacrifice Coral Trickster to Phyrexian Altar, you generate the exact mana needed to pay for Coral Trickster's morph ability, which lets you turn it face up once Missy returns it to the battlefield as a face-down 2/2 Cyberman artifact creature. This continuous transformation not only fuels your mana supply with the Altar, but also triggers untap utility from Coral Trickster itself to keep your other permanents primed for action.
