I'm playing through Pokemon moon and I caught a pichu in the beginning. I wanted to use alolan raichu because I liked its design. To make the most of it, I wanted to get electric terrain on it so I could use its ability. Could it get on raichu without breeding if possible? Its not that I can't do it but if there is an easier way, I will take it. Does pikachu learn it? Some of the move learning stuff for sun and moon is not accurate since it says that decidueye learns spirit shackle at level 1 but when I evolved mine, it learned it then.
