Yeah, it was more because in game, stuff has problems breaking a Raichu sub (i kno rite...) so wish was used to recover the HP lost from recoil and Sub.
Yeah, so get a male Smeargle with Fake Out, Encore, and Wish, and breed it with a Female Pikachu/Raichu that is holding a Light Ball (do you need a Light Ball, b/c I've got one if you need it, I don't know if you've used an AR for those kind of items because I haven't).
