The idea that an inanimate object can someone provide you with exactly what you need at exactly the right time.

The term comes from the popular Japanese anime/toy advert Yu-Gi-Oh, which centres around a card game played by the titular hero. Often when playing, Yu-Gi-Oh will call on the Heart of the Cards to provide him with the precise card(s) he needs to win the game, which it somehow usually does.
Doug: (thinks during a poker game) I have three queens and a jack. If I believe in the Heart of the Cards, the deck will provide me with the jack I need.
(Doug pulls a two)
Doug: DAMMIT
