Used to play in junior high, then quit. Then played in a geek store for a few weeks, during Mirrodin / Darksteel. Then quit. Recently started again with a couple of buddies.
I'm glad to say that I finally got over what people think of me when they hear I play Magic. Chances are I have more fun in the weekends than they do, on average. Go to a club sometime and just look at the people there. I swear to god: they're just standing there with a blank look in their eyes and a $6 beer in their hands, listening to god awful music. I'll have my nerdy card game, thank you. But I digress...
tl;dr This is my arsenal!
- Affinity deck with skullclamps. I know, cheap

at least I don't have any Arcbound Ravagers... as a matter of fact, I don't have a single rare in there and it's the most powerful deck I have. Shrapnel Blasts win the game.
- Red/Green. A classical deck with a lot of mana generation and Carbonize, Incinerate and Fireball for direct damage, with the added tactic of using those 'fetch' creatures from Nemesis (when comes into play, search your library for copies and put 'em in your hand etc). Helps thin out the deck, and you're always guaranteed a solid army. Added a few nice rares for flavor (Kamahl is always a nasty surprise), and there's this sorcery that gives a creature +3/+3 AND Double strike, which takes a nice chunk out of an opponent when used on a big trample beasty.
- Black/white rebel deck. The only reason I play this is because I still had some cards left from the Mercadian block, the most important being Lin Sivvi. Also I really like the art on those black/white nonbasic lands.
