Cubic Cleaner

Deathtouch, provoke, trample

"Through sheer tenacity, the Golgari managed to succeed where the Simic had failed. The cubic oozes that they created have roamed the sewers ever since, mindlessly consuming refuse, blockages, and vagrants. Scholars speculate that the oozes were a key factor in the eventual collapse and disappearance of House Dimir."
