In addition to standard two-player game play, the game also features “Raid Decks”, representing struggles involving large numbers of players against epic foes (although far fewer players are involved in the card game). These need one “Raid Master” and 3 to 5 other players. The Raid Master controls all monsters and foes, while the other players control the characters participating in the raid. Players who are victorious may be able to win certain “loot” cards from a 10-card treasure pack.

This treasure pack contains holofoils, and also contains a random insertion of the “loot” cards which trade aggressively due to their popularity with online Warcraft players. Upper Deck Entertainment also made treasure packs available from their UDE points store, although the cards in these packs are not holofoil.

The first raid deck, released in December 2006, features the dragon Onyxia (including stage 1, 2, and 3). The second, set within the Molten Core, was released May, 2007. The Molten Core game can be played in either “standard” version – where players compete against three random bossses and three set bosses, including Ragnaros – or “full” version, where players face all ten bosses.
