Idk if you still plan to make a Raichu vid, but I made a fun team with Raichu and Modest Specs Iron Valiant.
Notes: There’s no fire or grass resist, which can be a little tricky. Ogerpon and sometimes Weavile are good counterleads. Against Kingambit teams, don’t tera Iron Valiant. Treads is EVed to ohko Cinderace. The nicknames other than Raichu are Norwegian, Latin, Dutch, German, and French, respectively.
Alternatively you can Twave in Offesne MUs to support Hoopa and Pult. I really like this bidirectional support. Twave also beats Slowking G, funnily enough.
