It's not really a good idea to not evolve your Anorith. It's pretty frail, and the only thing it has over Armaldo is more Speed. But if you don't want Armaldo, you should go with Golem, Rhydon, or Aggron instead.
Or, since you already have so many physical attackers, you could replace it with a special attacker. I'd recommend an Electric type like Raichu, Magneton, or Manectric, or a Psychic type like Alakazam or Gardevoir.
Also, you should give your Ludicolo a stronger Grass type move instead of Absorb. You can get Giga Drain as a TM at Route 123.
