Id say that Cave of the Frost Dragon is the next best fit by color, though its just a bit too inefficient to activate to really move the needle, and Hive of the Eye Tyrant is the next most powerful of the lot but that black aggressive decks just dont tend to have the best tools in most Cubes

Just a two mana 2/2 that can tap for mana of any color is a great card, and this'll also put counters on stuff with regularity
