The past months I've been trying to make the more unpopular version of Faeries (Mono U) work, and every FNM I feel more and more comfortable with the deck.
This list is by no means perfect and I would appreciate your input.
First of all, this deck is BAD against aggro. Once something resolves, it is nearly impossible to get rid of. The only on board interactions are Vapor Snag and Cryptic Command.
It's strongest Match-ups are in my opinion, most combo Decks (Not all, KCI for example can be pretty tricky) and Control. This Deck wrecks storm like nothing, a mediocre player should not loose one round in a best of 3.
Faeries are Weaker against the Jeskai version of control, because they run so much single target removal. For that reason you probably want to board out some of the Mistbind Cliques.
Maybe I should run Dismember ? And if, is it strong enough to warrant a certain amount in the Mainboard, or should it be a sideboard card.
Mistbind Clique can feel bad against very removal heavy Decks but can win certain games single-handedly. Snapcaster Mage is obviously very strong, but this deck doesn't have that many instants so sometimes he is just a 2/1 with Flash.
The sideboard is the trickiest part. In blue it's hard do get artefact removal so i put in Pithing Needle to improve my Kci match-up, also my only answer to Plainswalker besides Cryptic Command .
I put in Notorious Throng because it's a fun card x).. Also lets you win out of nowhere against creature based decks.
EDIT: I added one Quickling, replacing oneSnapcaster Mage.
