How to execute it

  1. Cast the creature card in your hand by paying {0}.

  3. Gutter Grime triggers, putting a slime counter on it and creating a X/X Ooze creature token.
  4. Activate Carrion Feeder by sacrificing the Ooze.
  5. When the Ooze dies, Colfenor triggers, returning the creature card from your graveyard to your hand.
  6. Resolve the Carrion Feeder abilities, putting a +1/+1 counter on it each time.
