The following products are available or have been announced:

Starter deck – This UDEck box contains: A pre-constructed deck consisting of 33 fixed cards (one hero and 32 others) built around one of the nine classes; two booster packs; three oversized hero cards; and a rulebook. The oversized cards can be used in many play formats since hero cards are not shuffled into play decks. These decks contain one rare, six uncommons, and the rest are commons. Starter decks for both of the first two card sets are available, as follows:
Heroes of Azeroth Starter Deck – Contains cards solely from the first set, Heroes of Azeroth. 9 different 33-card pre-constructed decks are available.
Through the Dark Portal Starter Deck – Contains cards only from Through the Dark Portal.
Booster pack – 15 random cards – 10 commons, 3 uncommons, 1 rare or epic, and 1 hero card or loot card. Booster packs also have one UDE point card redeemable online. [1] Boosters are available for all released card sets.
Raid Decks – Raid Decks are specially designed decks used for a cooperative experience. They combine elements from the World of Warcraft (the team-based questing), and Dungeons and Dragons (the Deck Master).
Onyxia’s Lair Raid Deck – 3 epic raid boss cards, a 60-card ability deck, a 30-card event deck, 20 Onyxia Whelp tokens, and a 10-card treasure pack, as well as special rules for the deck. Cards in the treasure pack are not available in boosters, and any other raid deck exclusive cards are not considered part of the base set. Some of the treasure cards include the Tier Two Headpieces for all nine classes.
Molten Core Raid Deck – 10 epic boss cards, all from Lucifron to Ragnaros the Firelord himself! This deck includes a main deck for the first nine bosses, tokens to represent different Minions and a separate deck for the Firelord. It has a different ruleset than the Onyxia’s Lair Raid Deck. It comes with a ten-card treasure pack. The treasure packs include cards from the MMO like the legendary “Sulfuras, Hand of Ragnaros” and the Tier Two leggings.
The initial base card set is named Heroes of Azeroth, which includes 361 different cards. The color of the set number on the card indicates its rarity, using a rarity system similar to that of the online game; white for common, green for uncommon, blue for rare, purple for epic, and red for legendary. The only legendary cards in the base set are the three loot cards, which are variants of rare cards that have a scratch-off code. There are 22 epic cards, which are about twice as rare as the 110 rare (blue) cards. 99 uncommon, 114 common, and 16 hero cards complete the set. [2]

Future set expansions (not counting additional raid decks) are planned at a rate of 3 per year. The first such expansion, Through the Dark Portal, was released on April 11, 2007, and features 319 cards; 120 commons, 85 uncommons, 80 rares, 16 epics and 18 new heroes. The set also features three new loot cards redeemable for online items.[3]

A second expansion, Fires of Outland, was released on August 22, 2007 and features 246 cards; 80 commons, 78 uncommons, 73 rares, 15 epics and 18 new heroes. This expansion contains three new loot cards, one of which is the Spectral Tiger mount. This is the first expansion that did not come with starter decks.

The next expansion, March of The Legion was announced and includes subfactions, demonic allies and new types of hero powers and will be released sometime in November.
