All other permanents on the battlefield.

   Steps

How does this combo work?
1
Cast Phyrexian Marauder by paying 0.
2
Phyrexian Marauder enters the battlefield and dies as a state-based action due to having zero toughness.

Gutter Grime triggers, putting a slime counter on it and creating a X/X Ooze creature token.
4
Activate Altar of Dementia by sacrificing the Ooze.
5
When the Ooze dies, Colfenor triggers, returning Phyrexian Marauder from your graveyard to the battlefield.
6
Resolve the Altar of Dementia ability, causing target player to mill cards equal to the Ooze's power.
7
Repeat.
