Update 3:35 PM EDT: We've been talking about it and come to similar conclusions to that in the comments.
The Three Card Backs of Karazhan
We've spotted three different card backs which are related to Karazhan in last night's stream. We aren't certain how some of them are rewarded, but we suspect one is for Heroic Mode and the other is for an upcoming ranked play seasonal reward.
- The Blue Portal - Heroic Karazhan Reward
- Medivh's Invitation - August 2016 Reward
- Karazhan Nights - Purchase the whole adventure within one week of launch.
We believe The Blue Portal is the reward for completing Karazhan on Heroic as it is grouped with other heroic card backs on the stream. Additionally, normal mode adventure bosses have always used the "adventure season reward" card back and in the footage we've seen, Medivh's Invitation was used by the boss.
The Blue Portal 
Medivh's Invitation 
Karazhan Nights

Posted Aug 12, 2016 (Karazhan)For everyone wondering: You can buy the first wing with gold and the remaining wings with cash and you still get the cardback. Source: https://twitter.com/ywoo_dev/status/763797082679283712
