Rapidash is the type of Pokémon that, while not the worst at anything, is not the best at anything. In terms of power, it is overshadowed by the likes of Flareon and Mega Camerupt; in terms of Speed, it falls only 1 base point short of Pyroar; and in terms of bulk, Flareon and Torkoal are better choices. It also lacks a setup move outside of Agility, which is the only thing that makes it worse than Simisear. Its movepool is nothing to write home about, but it has coverage that Flareon does not and that Pyroar requires Hidden Power to surpass. However, it is worth noting that Rapidash gets Morning Sun, which carves it a niche over other Fire-types in the form of reliable recovery.
Rapidash @ Life Orb
Ability: Flash Fire
EVs: 4 HP / 252 Atk / 252 Spe
– Flare Blitz
– Wild Charge
– Drill Run
– Morning Sun
Flare Blitz is Rapidash’s main STAB move of choice and, backed with Life Orb (and potentially Flash Fire), it is nothing to mess around with. Wild Charge and Drill Run are coverage moves for (most) Water-types and Rock-types, respectively. While Flare Blitz and Wild Charge are powerful offensive moves, they do result in plenty of recoil, especially with Life Orb, not to mention Rapidash is vulnerable to hazards, so Morning Sun is a considerable option for increasing longevity.
Megahorn can be used to hit the likes of Ludicolo and Musharna—it is a guaranteed OHKO on offensive Ludicolo whereas Flare Blitz only has a 68.8% chance, and it is the only move Rapidash gets that can 2HKO Musharna. Quick Attack could be used as a priority option, but Flareon makes better use of the move with its superior base Attack. Substitute can be used to block Thunder Wave, Intimidate, and priority, but there is no other reason for it. Hypnosis can be used to put things to sleep, but it has really shaky accuracy, making it a gimmick at best.
