I've seen this In a different server, a room where there is an emperium, and a breaker would attempt to break it (duh xD), same properties and hp as what Is used on their woe. your time will be recorded and shown in your chatbox after, and there is also ladder rankings, it displays who were the top 5 fastest breakers in the practice emp room. I would also suggest a 5min cool down before you could enter again, to give everyone a chance to get it. :)
+1, this would give breakers the chance to figure out which set of cards work better, like to let them work it out on their own not to wait for woe and try, and ypu have competition, so it's hard to figure out.. And would determine whether the ak on emp is a myth or not.. Lol xD
P.s. I suggest one for The koe emp too :P
