>>33704610It learns Future Sight, which is a psychic-type move but does not deal psychic-type damage (so not super effective and no STAB), Dream Eater, with no way to put the opponent to sleep, and Psychic at a really high level. The only psychic move it can learn via TM is also Psychic, not available until you get to Kanto (but will still come much earlier than learning it by level up).
Dodgy is being generous, but I'm using one and it is pulling it's weight. Just having something that resists psychic moves has been helpful (don't have any dark or steel-types) even if he couldn't use actual psychic attacks for most of the game.
