Colfenor, the Last Yew
Gutter Grime
Endless One
Altar of Dementia

   Prerequisites

What do I need to start this combo?
Endless One in hand.
All other permanents on the battlefield.

   Steps

How does this combo work?
1
Cast Endless One by paying 0.
2
Endless One enters the battlefield and dies as a state-based action due to having zero toughness.
3
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 Endless One 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.

   Results
