Vampire: The Eternal Struggle
Vampire: The Eternal Struggle, originally named Jyhad, is a card game based on White Wolf's World of Darkness setting (Vampire: The Masquerade). It was designed by Richard Garfield and has the distinction of not being as broken as Magic. Garfield learned from his mistakes and created a game that wouldn't have arbitrary card limits, and play better, faster, and more balanced. He did this, but he had already created a monster with Magic, not to mention a bunch of religious fools got pissed off that the game was called Jyhad. So the cardgame never lasted long enough to get arbitrary card limits.
