How it works
Activate Carrion Feeder by sacrificing Danitha.
When Danitha dies, Fungal Fortitude triggers, returning Danitha from your graveyard to the battlefield tapped.
When Danitha enters the battlefield, it triggers, returning Fungal Fortitude from your graveyard to the battlefield attached to Danitha.
Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
Repeat.
This clever loop turns a modest sacrifice outlet into an unstoppable engine by exploiting a recursive recursion cycle. You feed Danitha, Benalia's Hope to Carrion Feeder, but Fungal Fortitude ensures Danitha immediately returns to the battlefield from the graveyard. That entry trigger is the secret sauce, letting Danitha snatch Fungal Fortitude right back out of the graveyard and attach it to herself once again, perfectly primed for the next sacrifice. The result is an endlessly repeating loop that grows Carrion Feeder into a creature of terrifying proportions while generating infinite death, entry, and sacrifice triggers.
