- 22 September 2011If Gutter Grime leaves the battlefield, the power and toughness of each Ooze token it created will become 0. Unless another effect is raising its toughness above 0, each of these Ooze tokens will be put into its owner's graveyard the next time state-based actions are checked.
- 22 September 2011If 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.
- 22 September 2011The power and toughness of the Ooze tokens will constantly update as Gutter Grime accumulates slime counters.
