The Big Bang Theory Wiki

Penny reluctantly playing Mystic Warlords of Ka'a

Mystic Warlords of Ka'a is a fictional trading card game that first appeared in "The Creepy Candy Coating Corollary" (S03E05). Sheldon, Leonard, Raj, and Howard all enjoy playing it. Sheldon and Raj lost against Wil Wheaton and Stuart in the comic book store tournament.

The Big Bang Theory blog released a photo of the Enchanted Bunny card and wrote "Here’s your first look at "Mystic Warlords of Ka’a" cards – more details to be revealed @ Comic Con 2011", followed by the release of the photo of several other cards, timed a few days apart. The game is an obvious spoof of games like "Magic: The Gathering".
