WotC Code:

The following text is a description taken from the WotC web site:

'Dungeons & Dragons Fortune Cards, sold in booster packs of 8 cards, give players fun new ways to survive the challenges of the D&D Encounters in-store play program, as well as their home campaigns. These cards give characters fun, temporary benefits that feel different from the benefits gained from powers and feats, without adding undue complexity to the D&D game.'

There are 8 cards in each booster pack.

Wizards of the Coast have released a FAQ and a How to Play downloadable PDF.
