Do what me and a friend have done. Just make sure you both are online. Then just challenge each other. This way you get a fair fight and no time outs. Also you can help each othere level your cards. Get enough friends to play and you can have endless hours of play time with smooth battles.
I accept every fight unless I'm either A) teaching a friend to play, or B) am having some weird computer problemd.
If its A, I will refuse it, if its B, sadly you're looking at the timer. Just a heads up for who ever is keeping track that likes to play.
