For PvP I would make the following slight changes:If it was a deck made for an accurate permanent/creature control, I wouldn't wrote "fast deck". I know it hasn't any creature control and it's vulnerable by oty, RoF, etc...
-1 Abyss Crawler, -1 Elite Wyrm, +1 Elite Pegasus, +1 Improved Fog
Definitely can't farm T50 with this though. 2 Steals not enough Permanent Control, too vulnerable to RoF/Fire Storm, and no creature control to deal with otyughs.
