I was looking back through the thread, and came back upon this duo. It seems really effective, and could probably stop my Togekiss/Gengar problem; although Togekiss will probably still be alive, I don't think Gengar could stand an Eruption followed by an Icy Wind on turn 1.
Not sure what else Typhlosion could have; Swift could probably do SOME damage after a Helping Hand. A kind of novel thing to do after blowing his Power Herb would be using Covet to grab another item, although I can't think of a time where you'd have enough of a chance to use it.
If Vaporeon doesn't have Leftovers, it would probably be a Chesto Berry. I'm inclined to put Protect in her last slot, but then again, Yawn certainly wouldn't be a bad idea either. Muddy Water could probably go over Hydro Pump, but sadly, under VGS rules, Vaporeon would only be level 50, and wouldn't be levelled enough to get Muddy Water.
