Frequent, inconvenient game freeze

Oberoni

It seems ever since the update, whenever I play with Jace, the game freezes at awful times in both the regular story mode and the event.

I was 1-2 turns away from beating Tyrant of Valakut (finally) the latest time this happened, so that was extremely frustrating.

The animations (such as the spinning trap gems) continue, but the game simply stops. Pausing doesn't work, clicking on the portraits will make a slight animation to acknowledge the click but won't bring up the character animation, etc. Last time this happened, the opponent just started taking his turn.

It's extremely frustrating that I can't complete the event because of this.

If it helps, here is my level 60 Jace deck:

Sphinx's Tutelage
Talent of the Telepath
Thopter Spy Network
Anchor to the Aether
Harbinger of the Tides
Sunken Hollow
Orbs of Warding
Disburse
Turn to Frog
Tightening Coils

The last time it happened, it was just after a "no more moves" rearrangement (which I see is a bug elsewhere in this forum), but I don't recall the other times having that same problem.
