Using the SoS method, I got myself a Pichu with 4 perfect IVs and the hidden ability; Lightning Rod. After it learned all the moves as a Pichu, I raised its happiness and it evolved. I'm not sure if I should evolve it in Alola, since Alolan Raichu is half psychic type (and Psychic is a good move to learn...) but doesn't have the Lightning Rod hidden ability, and Surge Surfer doesn't seem like the best ability to me, since Raichu is pretty fast anyway. Alolan Raichu DOES have a Z-Move, though I'm not planning on using Stoked Sparksurfer yet. Normal Raichu gets to keep the Lightning Rod ability throughout it's evolution line, doesn't have a Z-Move or the Psychic type. Is keeping Lightning Rod worth it, or should I wait for Pokébank to open for Sun and Moon?
