Posted this to reddit too, Curiosity is FANTASTIC in these decks. You might want to consider something to keep Guttersnipe alive through targeted removal, like Mizium Skin, and never drop more than one Curiosity onto the field at a time unless you know they aren't running sweepers.

I think I might drop the 2 Street Spasm for 2 Mizzium Skin . I'm just not sure what to drop for Curiosity .

If anything I'd lose the Redirect and Krenko, Mob Boss for Curiosity, since you'll be burning through cards so fast the extra creatures won't matter.

Bumped some stuff around to take advantage of some cards I got from Gatectash. Hello Skullcrack , Mugging , and Homing Lightning . Also toying with the idea of dropping Curiosity for Hands of Binding .
