Hearthstone's latest expansion Saviors of Uldum is live now, bringing 135 new cards to the game. If you want to start planning your decks immediately then head over to the official site for a list of all the cards.

As always a new set of cards means tinkering with gameplay. Saviors of Uldun will see Plague cards available, powerful removal spells that will affect both sets of minions. The Shaman's Plague card is undisputedly the most fun, turning all players minions into random murlocs.

Additionally, there will also be a new keyword, this is a word that appears on the card in bold text, known as Reborn. Any card with this text will return to the board with 1hp. There's also a priest spell that will grant this keyword to any minion. This, combined with the variety of other keywords in Hearthstone could potentially create some powerful synergies.

It will also see the return of Quest cards. If you've not played the game since Dr Boom's mere existence made you quit, these are objective-based cards that will change your character's hero power when the criteria have been met. This can range from cheaper spells for mages to minion buffs for the hunter and can really turn a game around.

If you log in with the next 90 days you will receive one of these nine quests cards at random for free. You will also receive 3 packs of Saviors of Uldun cards after completing a set of quests that will become available after your next login.

It was also revealed that a new Solo Adventure, titled Tombs of Terror will launch in September with more details being revealed next month. Hearthstone is free to play and is available on the App Store and Google Play.
