To be quite honest, Maushold isn't exactly viable or strong right now, but i tried my best to actually build a little team around it that at least covers the top meta or common mons
(that i mainly took from the poll , lmao):
I have no idea about the current state of the meta as i have been absent from ladder for last week pretty much because i was physically unwell , but I tried anyways:
Ceruledge tries to establish some sort of type-synergy with maushold, naturally having a good shot at beating the steel / ghost types of the meta.
I've focused this set around beating Annihilape, based off of this calc:
[+1 252+ Atk Annihilape Rage Fist vs. 240 HP / 0 Def Ceruledge: 296-350 (84.3 - 99.7%) -- guaranteed 2HKO]
This means that you can pretty much just continuosly click shadow claw and win.
You generally live Timid Flutter Mane's Shadow Ball and can try to outplay SpA Booster / Specs with Endure WP + Weak Armor tactics
Skeledirge also shouldnt really be a Problem since they cant burn you to go for hex and you can again just tech possible Specs sets with Endure WP, while yawn remains problematic (you could run taunt / sub over SD)
Gholdengo is the same type of setguessing dilemma were you can endure tech the choice sets but may struggle with non-choice sets, since you wont OHKO bulkier sets with Flare Blitz.
Maushold itself beats practically nothing apart from, perhaps fast specs Chi-Yu but it just gets bullied by about anything else
Sylveon takes out Dondozo and various dragons that delete Maushold and aren't really threatened by Ceruledge. Also this probably does not cover Donphan and Avalugg, sorry for that :/
