This remembers me that in my patch I changed the body background color from black to white to reduce the startup flickr too.

also, in my patch, I was using tellCard first, and pushCard in the catch block, which works perfectly. I don't know why you'd want to find which card was inserted because we should never need to insert a different card than what was inserted before. Either it was not inserted yet (because we don't have the cookie yet) either it was inserted (because we have the cookie and then it was the good one).
