Kaya's Ghostform + Phyrexian Altar + Greenwarden of Murasa

Kaya's Ghostform

Phyrexian Altar

Greenwarden of Murasa

How it works

1. Activate Phyrexian Altar by sacrificing Greenwarden of Murasa, adding .
2. When Greenwarden of Murasa dies, Kaya's Ghostform triggers, returning Greenwarden of Murasa from your graveyard to the battlefield.
3. When Greenwarden of Murasa enters the battlefield, it triggers, returning Kaya's Ghostform from your graveyard to your hand.
4. Cast Kaya's Ghostform by paying , attaching it to Greenwarden of Murasa.
5. Repeat.

This elegant loop transforms **Phyrexian Altar** into a self-sustaining engine by utilizing **Kaya's Ghostform** to constantly resurrect your sacrificed threat. When you feed **Greenwarden of Murasa** to the Altar for mana, its death triggers the enchantment to return it straight to the battlefield, while its own entry trigger conveniently plucks **Kaya's Ghostform** right back out of the graveyard to be recast. Because the Altar generates the exact black mana needed to replay the enchantment every cycle, the entire sequence closes the loop seamlessly without losing resources.
