First off an annoying nitpick: take 12 speed EVs out of politoed, which still allows you to outspeed tornadus. Unless you are concerned about outrunning serperior and scolipede. I guess they go in HP? Defense? I don't know
Actually, that is about it. I don't know if dual scrafers is a great idea, but, whatever drowns their boat (see what I did there). Jirachi is weird, I will probably t set it soon.
