World of Warcraft Trading Card Game: Onyxia's Lair Raid Deck

Features the black dragon Onyxia.

Raid Decks represent struggles involving large numbers of players against epic foes. Raid Decks are specially designed pre-constructed products used for a cooperative experience. They combine elements from the World of Warcraft (the team-based questing), and Dungeons & Dragons (the Raid Master). One player, the Raid Master controls all monsters and foes, while 3-5 other players control the characters participating in the raid.

A Raid Deck typically contains epic boss cards, decks for the boss characters, tokens to represent minions, custom rules for the raid, and a treasure pack, intended as a reward for players who are victorious in the raid. The treasure pack contains holofoils and sometimes contains a random insertion of a loot card. Upper Deck Entertainment also made treasure packs available from their UDE points store, although the cards in these packs are not holofoil.
