Oozes are a creature type associated primarily with green, black, graveyards, +1/+1 counters, and creatures that grow by consuming various resources.
Necrotic Ooze borrows activated abilities from creatures in graveyards, while Experiment One grows through evolve. Slime Against Humanity gives Ooze-thusiasts the option of filling a deck with copies of one increasingly dangerous Ooze-based sorcery.
