Kaya's Ghostform + Altar of Dementia + Renegade Rallier

Kaya's Ghostform

Altar of Dementia

Renegade Rallier

How it works

1. Activate Altar of Dementia by sacrificing Renegade Rallier.
2. When Renegade Rallier dies, Kaya's Ghostform triggers, returning Renegade Rallier from your graveyard to the battlefield.
3. When Renegade Rallier enters, it triggers, returning Kaya's Ghostform from your graveyard to the battlefield attached to Renegade Rallier
4. Resolve the Altar of Dementia ability.
5. Repeat.

This self-sustaining loop relies on a clever cycle of resurrection and recursion between Altar of Dementia and Renegade Rallier, protected and enabled by Kaya's Ghostform. When you sacrifice Renegade Rallier to Altar of Dementia, Kaya's Ghostform triggers upon its death to instantly return the creature to the battlefield. Because a permanent left the battlefield this turn, Renegade Rallier's revolt ability triggers as it enters, pulling Kaya's Ghostform right back out of the graveyard to enchant it once again. This creates an endless cycle that mills your library infinitely while generating boundless entry, departure, sacrifice, and death triggers.
