Yeah, forgot about Volcarona, Quiver Dance + 3 attacks is still pretty decent in the rain.

If you don't mind my nitpicking about your SQSA comment, I'd like to make a quick point.

"you never run Fire-types in the rain, it's redundant"

Volcarona and Moltres are actually very effective in Rain due to Hurricane. Fire Blast still roasts several Steels.
