Hearthstone Beginner

You can still get this achievement by playing on a table (and winning ?) and get a card to add to your collection. I tried it today and got my first card which gave me progress.

So, how to find a table ? I know 2 ways for this (maybe there's more)

• 
  
• You can ask a friend that already have the achievement to summon a table, play with you and let you win.
• 
  
• You can go the the table located behind the story telling show during WoW anniversary, and have someone let you win.
• 
  

But it may take some time and your friend need to be somewhat active and sit down at the table every 3/4 minutes, so you can also, use a second account (even free trial), take your favorite capital portal to Caverns of Time and play with yourself, so you won't bother anyone else.

Update March 15th:
- The event duration has been extended by 96 hours, and is now scheduled to end on Friday, March 22.
- For the remainder of the event, the boss portal will open every 30 minutes (was every 60 minutes).
- Players can now collect missing cards by using the Hearthstone Gameboard toy to defeat others in a friendly game. It will continue to drop cards after the event ends.

Every 30 minutes, an Ominous Portal with a 5-minute timer will spawn in Valdrakken, Stormwind and Durotar (Orgrimmar). Once the timer finishes, Whizbang will spawn and summon 3 iconic Hearthstone minions - Chillwind Yeti or Boulderfist Ogre, Patches and Dr. Boom.
Defeat them to earn Hearthstone-themed rewards!

Its a accountwide Achievment. All Characters from your Battle.Net Account will count do it.
To eliminate the chances to get a wild card drop: The wild cards are Unique (10). So buy them from nearby Shady Dealer till you have 10 of those. 5 cost 20 silver. As they are unique, you wont get more of those as random drop from the bosskill.

Stormwind
/way 34.0, 21.0
Durotar
/way 53.1, 16.2
Valdrakken
/way 62.2, 67.0

We'll know more details either before or when the event hits in March.
