When I originally wrote this script, space didn't work to reveal the cards—it only opened the next pack. I'm glad to hear they finally implemented an easier way of opening packs.

I'm going to leave the original script as-is. I haven't played in a while, so I won't be able to test any changes. However, @temzky's version looks like it would work fine—I recommend going with that one over mine if you run across this in 2021.

Since this is where I landed searching for a solution to the horrible HS pack opening experience, I whipped this up as an iteration of the above. It simply activates the Hearthstone window and starts pressing the space bar. As soon as Hearthstone is not that active window anymore, it quits.

(This is the entire script):

WinActivate, Hearthstone
IfWinNotActive, Hearthstone
{
	MsgBox, Heathstone doesn't appear to be running! Exiting...
	ExitApp
}

Loop {
	Send, {Space}
	Sleep, 500
	IfWinNotActive, Hearthstone
	{
		ExitApp
	}
}

Esc::ExitApp
