Trick Room lets Cthulauder take advantage of its very low Speed. Superpower boosts Attack and Defence with Contrary. Knock Off is a reliable STAB move. Protect is usually preferred, but Psycho Cut can be used as a secondary STAB so Cthulauder isn't walled by Fairy types. If you're running Gaia Berry, run 236 HP EVs and put the extra in Defence to give Cthulauder a HP stat divisible by 4.
