Dual Weather challenge? I already have one double weather team. It's pretty good, but it's held back by the two weathers I chose being pretty much opposites of each other. Still, I'm in! (I'll be making a different one though, the ol' Rain and Sun team isn't quite up to snuff for competition I don't think)

Lol, number 6 again.
"Whether Castform the Weather Pokemon can weather the weather is dependent on whether the weather that it's weathering is the proper weather for it to weather. Whether the opponent can weather the weather is also subject to whether the weather that it's weathering is the right weather to weather. Whether Castform can weather the opponent is once again dictated by the weather and whether that weather is the favorable weather for weathering. But most importantly, you should know whether there will be weather to weather rather than what weather they will be weathering and whether they can weather that weather."
