Campaigns - Unlocking theme deck

Hi everybody.
Someone knows how can I unlock some theme decks playing campains?

Thanks.

 

Hi dear fella!

The only theme decks you can unlock without spending game coins are the basic ones. They are unlocked via the "Walkthroughs" which are the very first 8 at the campaign eyelash.

 

Thank you.

 

So, by unlocking the above decks, are you able to use the cards in Ranked, and are you able to use them to create your own battlegroups, or do you have to stick with the bg/deck you unlocked?

 

Sadly, the decks can't be altered (neither the upgrades on the champions) so you'll have to stick with them as they are until the greens update them.

BUT you can use the decks wherever you want (Dailies, Campaigns, Practice, Battlegrounds, even Ranked games).
