{Contagion Clasp} and {Contagion Engine}? Especially the latter, it functions as really good removal as well! Maybe other Proliferate spells also? {Tezzeret's Gambit} is pretty sweet, and I'm a big fan of {Volt Charge}.

Yeah dude holy crap, {Inexorable Tide}, {Steady Progress}, {Thrummingbird}?!?!? I'm pretty sure only about 5 of the 15-ish Proliferate cards are NOT beneficial to this deck. There's removal, counters, geez. Check 'em out for sure!
