It's certainly the color with the most potential for abuse. It also has one of the highest skill caps to use it properly. That's where it gets a lot of hate. Less skilled players end up seeing how good it is, so they try to make a build, and end up stuffing it with 80% control. That just results in pissing people off more than getting a win. Honestly though, blue/black and blue/white are way more nasty than any mono blue deck I've ever seen. The only two decks I was forced to dismantle because everyone simply refused to play against them, was a blue/white Stasis deck, and a blue/black Migraine deck.
The Migraine deck in particular was brutal. I won a 6 man battle royal with that thing without taking a point of damage. I was a bit of a pariah after that one. Nothing about the deck was cheap or anything, it was just very efficient. Kinda bummed me out pulling it apart. A victim of its own success.
