Ormaria is the second best Pokémon in the entire game, right after Asphere in its three formes. The possibilities are endless for Ormaria when it comes to movesets: Swords Dance, Quiver Dance (my word...), Nasty Plot, Hydro Pump, Focus Blast, Shadow Ball, Giga Spark, Psychic, Dark Pulse, Cosmic Power, Wish, Baton Pass, Energy Ball, Bug Noise, Diamondblast, Icicle Crash, and so on and so forth.
Cleric, Physical Attacker, Special Attacker, Wall, Staller... Ormaria can do it all! The only major letdowns for Ormaria are that she cannot learn Shadow Clamp, which is substantially better than Shadow Claw, and when Procyon and Deneb fully release, her defensive roles may be outclass by her preevolution, Ordina, thanks to Eviolite.
With her phenomenal bulk, superb offenses, high speed, and godly movepool, Ormaria is the prime example of a perfect Pokémon.
