Kaya's Ghostform + Phyrexian Altar + Timeless Witness

Kaya's Ghostform

Phyrexian Altar

Timeless Witness

How it works

1. Activate Phyrexian Altar by sacrificing Timeless Witness, adding .
2. When Timeless Witness dies, Kaya's Ghostform triggers, returning Timeless Witness from your graveyard to the battlefield.
3. When Timeless Witness 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 Timeless Witness.
5. Repeat.

This elegant loop turns a simple recursion trick into an infinite engine, powered entirely by the synergy between Kaya's Ghostform and Timeless Witness. By enchanting the Witness with the Ghostform, you ensure that sacrificing it to Phyrexian Altar doesn't send it to the graveyard for good; instead, the Ghostform triggers to bring it right back to the battlefield. Because the Witness enters the battlefield fresh, its own ability triggers to pull Kaya's Ghostform right back out of your graveyard and into your hand, ready to be recast.
