I assume you mean The Gathering. And yes. Yes I do. Not standard, though. I don't have the time or money to keep up with it.
I don't, but all of my friends do - and they've been trying to drag me into their mayhem for the last two years. I can feel my resistance slowly crumbling. xD
I play casually, but I usually lose because I've only dumped a couple hundred into my cards and I don't have the best system mastery.
I've found I'm a big fan of blue and black, with some green tossed in there. Though I did make a blue and red burn deck but I haven't had a chance to test it yet. I'd like to play more casually but between work and not having the money I'm usually stuck without a place to play. I'd love to be able to find some people just to hang out somewhere and play...
