Collectible Card Crack: How to Scratch that Itch Without Going Broke

I have a nearly uncontrollable desire to play CCGs.  Since that first sense of wonder when learned Magic: the Gathering 15 years ago, I have always felt drawn to these games.  I certainly don't miss the financial and chronological investment playing CCGs competitively requires, but there are still a lot of gaming experiences CCGs provided that are tough to get out of board games or RPGs.  I played Magic, Rage, Spellfire, Dragon Dice and Battletech in high school, in college I moved on to L5R, Shadowfist, A Game of Thrones, and lots of Raw Deal CCG.  When college was over, I quit the gamer crack cold turkey and tried to move towards board games since they are cheaper and less time consuming, but I still find myself drawn to the deckbuilding and variety of CCGs.
