Not sure if the contents of my reply is gonna be seen as off topic, as my answers aren't really related to the thread to begin with. Hopefully you won't mind, just wanna play it safe, haha!
I have to agree, it was a bit sad that Surf also hits the partner Pokémon in doubles, but hey we can take advantage of that for those Pokémon with the Abilities like Dry Skin, Water Absorb and so on. :)
While those moves are popular since their debut, funnily it took me to Gen III to promote them as one of my regular moves! :D
I heard Toxic never misses if it's used by a Poison-type Pokémon in Generation VI games, you must love that adjustment a lot!, haha.
