United in Stormwind will add 135 new cards to the game when it arrives on August 3. It adds a new keyword, Tradeable, which allows you to send a card from your hand into your deck to gain one mana and draw a new card. You can see all the card reveals past and future here.
Other new elements in the expansion include profession tools, zero-attack “weapons” that have wide-ranging effects, and mount spells that buff a minion and produce another minion when the original is killed. Each class also gets a questline, which are similar to quests but have three steps to full completion, which grants your class’s leveled-up mercenary.
In non-expansion-but-still-coming-soon news, Battlegrounds players will soon have cosmetic options to deck out their heroes in new skins and even a replacement for Bartender Bob: Ragnaros, the Tiki Lord. (His deals are likely to be hot, hot, hot!) The Fire Festival also returns next week with the usual bonus packs for completing quests and a new skin for Malfurion. The next Book of Mercenaries entry, for the demon hunter Kurtrus Ashfallen, arrives on July 13, with Gul’dan’s entry just a week later, on July 20.
Meanwhile, today’s patch offers pre-purchase options for United in Stormwind, while making several changes to Battlegrounds heroes and minions. Darkmoon prizes also make their return and will appear in 1/4 of matches. You can read the full patch notes on the Hearthstone site.
