Enduring Vitality + Zur, Eternal Schemer + Phyrexian Altar + Barbarian Class

Enduring Vitality

Zur, Eternal Schemer

Phyrexian Altar

Barbarian Class

How it works

1. If Enduring Vitality is not a creature, activate Zur by paying 1, causing Enduring Vitality to become a creature.
2. Activate Enduring Vitality by tapping it, adding .
3. Activate Phyrexian Altar's second ability by sacrificing Enduring Vitality, adding 1.
4. When Enduring Vitality dies, it triggers, returning itself from your graveyard to the battlefield as an enchantment.
5. Repeat.

This clever loop turns Zur, Eternal Schemer into a master animator, using its ability to turn Enduring Vitality into a creature whose mana value safely satisfies its own transformation condition. Once animated, Enduring Vitality taps for mana thanks to its own bestowed ability, letting you immediately feed it to Phyrexian Altar for sacrifice mana. Because Enduring Vitality's own death trigger brings it right back to the battlefield as an enchantment rather than a creature, it neatly resets the loop so Zur can animate it all over again. Meanwhile, Barbarian Class sits quietly on the board, ready to grant its passive and activated benefits to your forces while the core engine runs infinitely.
