2 NEW CARDS BACK appear on patch 9.0 with promotion

How do we get it ?

wow. they look great. maybe the season rewards for the next two months?

it says something about promotions !

Warlock and the left one, very nice !

Hmm, they look like two sides of the same coin, one good and the other evil. I'm officially intrigued.

I'm assuming it has to do with the Twitch Prime announcement that Blizzard made a few months back saying that some loot would be available to Twitch Prime subscribers.

Call of the Void is most certainly Warlock. Call of the Light suggests Priest or Paladin but they just got new heroes. So I'm curious about that one. 

"Call to the void" and "call to the light"

Probably for the next two months ?

Or some extra reward for the adventurelikequest in KFT?
Edit: eh now I know it is Twitch reward 0:-I

Updated strings from the patch say "Twitch1" and "Twitch2" for each card back. So looking likely that they are Twitch Prime bonuses. Good for me!

Is it for new users only ? (I know dumb question but still)

I'm guessing that I should have linked my Amazon Prime account to my Twitch profile before downloading the patch then D:

twitch prime rewards.. may come with packs? Those card backs are awesome, though. I'll probably get prime for a month for these then cancel 

 what to do?
