Vampire: The Eternal Struggle

This 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 towelheads got pissed off that the game was called Jyhad.
