Well, that depends entirely in which water and grass types you want. Azumarills are common in the route after Midna iirc, and they can have huge power (mine did, hehe). As for grass types, well, there are petilils in a route. Petilils that can have own tempo, learn quiver dance and petal dance. Tell me that's not evil >

LOL yep. A few things: Are Budew/Roselia available? Where are moon stones and shiny stones? Is Buizel available?

Ok ok let's go sloooow...

First, Buizel, I think there are some, but can't recall where.

Moon stone...you get one from a NPC in the future. Maybe even 2, iirc.

Shiny stones, if not mistaken, have to be purchased in the last city available in the game as of now.

And budew, I think, you have to find someone's friend safari who has it.

Anyway, there's a wiki of this game, you know? Look in there, sure there will be more info...
