Enduring Renewal + Phyrexian Altar + Composer of Spring

Enduring Renewal

Phyrexian Altar

Composer of Spring

How it works

1. Cast the enchantment creature by paying its mana cost.
2. When the creature enters the battlefield, Composer of Spring triggers.
3. Holding priority, activate Phyrexian Altar by sacrificing the enchantment creature, adding one mana of any color.
4. When the enchantment creature dies, Enduring Renewal triggers, returning the enchantment creature to your hand from your graveyard.
5. Resolve the Composer of Spring trigger from step 2, putting the enchantment creature onto the battlefield from your hand.
6. Repeat from step 2.
