depends on what field you get if it is corrosive mist field just get a flying type pokemon with gust so your pokemon will not get poison everytime because even if you heal it your pokemon will just get poisoned every turn or just simply get a ampharos(obtainable at jasper ward) and use electric terrain also evolve your espur it gets psyshock and its very powerful with 80 special also if your meowstic is male it gets prankster which allows status moves to go first so even if your pokemon is slower it will always moves first like using light screen(lv13) and reflect (lv 35)

 

BTW mightyena with moxie is very powerful

Espurr definitely helps here. Quiladin, not so much. If you're fighting on a corrosive mist field, you can use it against him. I like to get a sturdy pineco on his crobat just to self-destruct and ohko it with the mist.
