So this update actually has gotten me to make a post :) in a good way.
First of all, I just updated from 1.6.3 to 1.7.6 and OMG what an amazing improvement. The perfect "rushing" of cards being played and end turn as opposed to roboticly 3 seconds in between does wonders. And the checking of cards is a perfect addition to blending in ;)
Though I do have a minor complaint. I watched the first game being played out on a hunter deck w/ juggler. In the previous version it would lay down minions before attacking with juggler out. Now, 2 turns in a row, it attacked before playing minions, including attacking a shieldbearer @1hp w/ my juggler before summoning.
In addition, in the previous version (I don't know about current, as I haven't added the card back in), tracking wouldn't get used. at all. so I just ended up replacing it with another, but I don't know if that was intentional or not.
Other than that, absolutely fantastic update. Please keep up the good work :)
