What card games have you ever gotten addicted to?

I used to play Pokemon card games in my brother's Gameboy Advance. :P I didn't want to have actual trading cards as I won't have anyone to play against or trade with. :P I have friends who still play Magic cards even though they're already college graduates. It must be pretty addicting.

Well, I use to play them, be it in video games or in actual card game. A friend of mine during high school introduced me to it and I got interested in them too. I slowly stopped during college as things had to be set aside for more important things to attend to. Yeah, it was really interesting as you do have to construct your own deck and with the strategies that you can think of just to win over a match against other players who also have their own strategies. (^_^ )

My friend tried to explain the game to me before. How it works, what you do, the rules of the game, etc. It was just all so confusing to me. I couldn't get the hang of it. Or maybe it was just because I was never really interested in it anyway.
