I used to play MTG shortly after it was created (mostly Revised Edition and a few of the expansions that came out around that time). It's a great game, but I haven't played in 15 years or so.
A collectable card game I liked even more than MTG was called Vampire: The Eternal Struggle (originally called Jyhad). It's based on the Vampire: The Masquerade RPG world. A typical game lasts quite a bit longer than a MTG duel and is better with 4 or more players so it's harder to get people together to play, but it's outstanding AFAIC.
