The day they change Counterspell from 'interrupt' to 'instant', blue becomes a creature deck all the sudden. Plus some of them blue creatures are either hard to cast (UU minimum) or doesn't have the best ability other than, well, counter target spell.

Or maybe I'm just used to weenies (G & R). :-)

(Heck, even W & B weenies are easier to cast)
