I found some possible checks for rapidash:
(+ -> -) quagsire, avalugg, sandaconda, cofagrigus, piloswine, wishiwashi, lanturn, stunfisk-galar.
-----------------------
Quagsire, avalugg, sandaconda, cofagrigus, piloswine can perfectly hold their hits even at +2 (if they are at 100%) and defeat them with super effective/powerful moves (avalugg, cofagrigus-body press)

Wishiwashi can be a safe change because he can take his punches and win a 1vs1

-----------------
Wishiwashi and lanturn can be a "safe" change as they can handle a fblitz and then a wcharge/high horse (if they are at 100%)

Wishiwashi can withstand the blows of the enemy wishiwashi and with toxic force a change not to die, vs lanturn wishiwashi can withstand 2-3 Volt switch and if it stays you can put toxic and then u-turn(if they are at low life they can die vs rapidash)

----------------
In the case of stunfisk-g we will analyze in case 100vs100( because if you change x Mon by fisk,he dies by fblitz+possible hazards+move above)
In 100vs100 rapidash he can't ohko Fisk, whereas he can.

For this reason it is advisable to wear it out first with wishiwashi/hazzards/another Mon from the team.
Finally wishiwashi can help rapidash with u-turn(more pressure) xd
