Simic's Greatest Failure

This creature costs {1} less to cast for each creature type among creatures you control.
During each player's upkeep, put an ooze counter on another target permanent. Permanents with ooze counters on them cannot activate their abilities. If a creature has an ooze counter on it, it is a green Ooze creature with base power and toughness 2/2.
