Phyrexian Altar + Infuse with Vitality + Dualcaster Mage

Phyrexian Altar

Infuse with Vitality

Dualcaster Mage

How it works

1. Cast Infuse with Vitality by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Infuse with Vitality, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Infuse with Vitality.
5. Holding priority, activate Phyrexian Altar by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.

This clever little loop turns a modest combat trick into a self-sustaining engine. By casting Infuse with Vitality and intercepting it with Dualcaster Mage, you set up a recursive dance where the Mage copies the spell targeting itself, ensuring it always comes right back when sacrificed. Phyrexian Altar is the linchpin that harvests this cycle, turning each sacrificial return into a fresh burst of mana while feeding the life-gaining and death triggers provided by the spell.
