OK today i n the arena i had the weirdest glitch ever happen. I was exiting the ds arena and i got to the lobby but there was no one there. So i looked around and i saw that the usual rope was let down I went down to the original arena and there was a clockwork and i fought him i mean its not like i had anything to lose.and when i was fighting him i didn't have any cards so it was on and on and no one would attack so i had to flea. I tested it again to make sure that it wasn't just like a one time only thing and it happened again! So whatever you do do not exit the ds arena to the lobby.
