mimik isn't really a wallbreaker compared to almost any other mon on hyper offense so you should probably not repeatedly refer to it being one. It's mainly just used as a panic button revenge killer and a spinblocker on HO, and wallbreaking will have to be covered elsewhere either way.
Mention araquanid in hazard setters (maybe over Azelf bc suicide lead sr azelf has been somewhat trending down as of late) because mimikyu's nice on webs.
Mimikyu struggles to break though all of those steels, to be honest. It can break through Scizor and Cobalion if they hard in on mimikyu, it swords dances on the switch, it is Ghostium Z, it still has disguise up, and it doesn't get flinched by Cobalion's Iron Head, but i would still call that struggling. Rephrase and condense the sentence to accommodate.
Technically a quality issue: swap the order of Superpower Scizor and Lucario, because you aren't using Superpower Lucario.
