I'd sideboard Pupeteer Clique, mainly because YOU don't have that many nice creatures to get back anyway, and I'd DEFINITELY play a 4th Mistbind Clique, it's what wins games. Also, you have 4 cip tapped lands (the Conclaves) that cost 2 to activate and only 3 Mutavaults, and you're playing less lands than I'd like to see in Faeries. I'd stick with 4 Mutavaults and 2 Conclaves TOPS (I play with 1). I like RUse's idea, but spellstutter is not that big, it's mroe of a support card, so that's a combo you're not pulling often. I'd probably run Broken Ambitions over it. You could also consider dropping 1 Vendilion Clique and the Pestermites for Remove Soul or something along those lines, because heavy aggro WILL be a problem. As for Terror, I'd think about running less copies of it, and running Agony Warp, you get to kill black creatures and you get to make a lot of cooler plays with it. Oh, and please please please lose Reflecting Pool for a full set of Underground River, you need your colors and you need them early. And consider maindecking Thoughtseize, it's a lifesaver!
