Like the MMORPG, Upper Deck's trading card game for World of Warcraft includes several references to TV shows and pop culture in its art and flavor text, with its recently released expansion Fields of Honor being no exception.

The two cards above are clearly inspired by He-Man/Masters of the Universe, modeling Adam Eternum after Prince Adam of Eternia, and Keldor the Lost after He-Man's arch-enemy Skeletor. The former card even adapts He-Man's famous transformation catchphrase into "By the power of Greybeard, I have the power!"
