Enchantment
Whenever a nontoken creature you control dies, put a slime counter on Gutter Grime, then create a green Ooze creature token with "This creature's power and toughness are each equal to the number of slime counters on Gutter Grime."
If you control more than one Gutter Grime, each Ooze token remembers which one created it. The power and toughness of that Ooze will be equal to the number of slime counters on that Gutter Grime only.
