Leapfrogger buff would stack.  So a golden Macaw left as the only unit on board could have say 10 stacks (made up number).  Once it attacks it has 30 stacks.  Attacks again it has 90 stacks.  Then 270.  Giving +2/2 or, more likely +4/4 each stack and it snowballs to high numbers really fast.

I thought "Why would it summon turtles now?" and you made me realize how slow I was.

After the latest patch I'm unable to play on my Amazon Fire tablet.  I uninstalled/reinstalled and I can play when selecting the "I'm new" button but when I select "Log in" it goes back the opening hearthstone screen and freezes.  I saw a thread on the tech support forums of people saying they had the same issues and also made a post there.  Has anyone else experienced this or somehow found a work around?  Thanks for any help.

When opening card packs, I like to hover over each card without clicking to see the aura glow. Then I flip the cards from no glow>blue>purple>yellow.

With the patch it appears that all heroes have "complete crowns" for all wings of Dalaran Heist even though I haven't completed runs with them. I know there are some bugs with today's patch.  I know its a super small bug, but has Blizzard mentioned it yet?
