Hello,
I finally got my Closed Beta Key yesterday, and i thought let's give it a try.
After i entered the game, i was like "Huh, wtf this is amazing, i can't wait to play the first game".
On the first look, it might look a bit complex, but after you found out how the game works, its completely easy.
When you enter the game, you have to play against 10 enemies (computer based), to get into the game.
After those 10 enemies, you have the option to play against other Players in the world, or in campagne mode.
In the campagne mode, you can unlock 10 heroes.
Warrior
Warlock
Mage
Hunter
Paladin
Shaman
Priest
When you unlocked all those heroes, you can play in "Arena" mode, in the Arena mode.. you can play with random decks versus random people,
means: Everyone have the same abilities.. Everyone got the same luck, so its completely fair.
I can't write all this stuff down now.. you have to find out yourself :)
In my opinion, it's a really amazing game.
Here are some videos, which explains everything i wrote:
