sleep clause just means that you cant put two of their pokes to sleep AT THE SAME TIME. put one to sleep kill it. then put the next to sleep. thats perfectly legal.. also if they use rest and put themselves to sleep you can still put other pokes on their team to sleep.
I see. I kept expecting the thunder wave which is why I was going for all those substitutes but I guess you faked me out pretty well. It's nice to see someone using Togekiss though. I don't see him much anymore.
