Deck is pretty straightforward, here's how I play it.

Try to get the Tormented/madcap combo out turn 2. If that isn't really an option, try rushing out the hasty creatures ASAP. Drop a madcap for instant fun.

Desecration Demon is a nasty thing to put down, and it really wouldn't be expected, judging how this deck is very Aggro-ish.

Control how many creatures they have on the field at once, and you should see a win fairly quickly.
