Game "freezes" sometimes when I play "choose one" cards

They are working on it.

[Updated 12/6] [Hearthstone] The team is investigating continued reports of crashes or softlocks, particularly from playing Choose One cards and Titans. The team has isolated the issue: it is caused when one of these cards in in your initial hand to start the game, mulliganed away, and then redrawn and played later in the game. Now that it has identified the issue, the team is working to get a fix out as soon as possible. As a workaround in the interim, restarting your client after the triggering incident should avoid or resolve the issue.
