Please remember to end all of your active battles that you've finished. I can page up 15 times on the list of open matches. It's been known to mess up trades, and confirmed to be the main problem behind non-functioning tournaments. I know some people leave them open to prevent card loss: that isn't how it works. You took the risk by playing that opponent. (and ogre king doesn't take any cards, no reason to leave that open to begin with). If it's bugging and not playing, and that's why you left it, there's a leave match link under the battle screen.
