all your good attacks are special attack, so special + and def -, which would allow you to use something like mega horn for extra coverage move
Not in the slightest Galar Rapidash gets some very good physical moves to go with that base 100 attack.
Megahorn, Play Rough, Wild Charge, Drill Run, High Horsepower, Zen Headbutt, Psycho Cut, Throat Chop and Swords Dance. Most of the above are pretty easy to get from the raids too.
Edit: Edited out some of the normal Rapidash ones that I missed. The moves that it gets provide it with decent damage moves for all 3 of its weaknesses. Drill Run and High Horsepower for steel, The same two and Psycho Cut for poison and Throat Chop for Ghost.
Personally id run an Adamant or Jolly Nature with Band and go with Drill Run, Play Rough, Psycho Cut and Throat Chop/Megahorn. Throat Chop will also make Toxtricity pretty much useless and in danger of a Drill Run. If you want Leftovers instead of band you could drop out Psycho Cut in favor of Swords Dance.
Edit2: With such a lackluster Spa stat Rapidash just doesnt hold a candle to say Gardevoir which has 25 less base speed but has 55 more base Spa as well as having better special moves.
