I playing with some peoples, the card is waiting in the air & Waiting game.
1 min, 3min, 5min.
Recently, it was too much.
PS: No problem with my internet connection.
What kind of nonsense is this ? 
it usually happens when the connection to the hearthstone servers break down for a short while.
with browsing the web you don’t notice if it takes a second longer to load, but sometimes the game can’t reestablish the connection.
I don’t think this should still be an issue (as in: they should’ve reliably fixed this by now), but you can work around this by closing the game and restarting as soon as you notice this floating card thing. then the game will reconnect.
