Gutter Grime

Altar of Dementia

Requires
Colfenor, the Last Yew must be on the battlefield. Gutter Grime must be on the battlefield. Walking Ballista must be in hand. Altar of Dementia must be on the battlefield.
Steps
  1. Cast Walking Ballista by paying 0.

  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 Walking Ballista 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
Infinite death triggers. Infinite ETB. Infinite LTB. Infinite mill. Infinite sacrifice triggers. Infinite self-mill. Infinite storm count. Infinite slime counters on Gutter Grime.
