My Noctowl would have Roost, Night Shade, Hypnosis and Whirlwind. Noctowl has poor offensive stats, but Night Shade ignores that. Roost for recovery (and it has good HP and Sp.Def for tanking capabilities), Hypnosis for sleep and Whirlwind if your opponent tries stat-ups (Calm mind etc.); or if you have a Spiker. You can also put opponent to sleep and then Whirlwind their entire team to sleep it it's not claused (ordinary linkbattles allow everything IIRC).

Ofcourse ingame you'd probably need Air Slash/Psychic/Shadowball to train and get through the game.

Still, it's an alternative set.
