What are some viable Pokemon for the Battle Tree?

I am currently making an USUM Super Singles (no legendaries) Battle Tree team and I need some help deciding what to have. I’m already using Metagross-Mega as it justwrecksand I need: a Special Attacker (Choiced or Otherwise), and something else that’s not called Aegislash, Toxapex or Pyukumuku (AKA a wall). Also, any help with the Metagross would be appreciated (moves, EVs, nature etc). Thanks!

Metagross @ MetagrossiteAbility: Tough ClawsEvs: 4 HP / 252 Atk / 252 SpeAdamant NatureIvs: 0 SpA- Bullet Punch- Meteor Mash- Zen Headbutt- Earthquake

Note: Do the AI use entry hazards ( Stealth Rock, Spikes, T-Spikes)? I was thinking of Volcarona.

Setup sweepers like Kartana or Naganadel are really good (I got my Naganadel from the shiny poipole card event thingy) bc the computer players in the battle tree arent that good so you can usually use swords dance or Nasty Plot on them. I like Naganadel better bcuz you can use the z crystal and Draco meteor and it’s really strong plus he has Beast boost but I guess kartana works to.

Also they do use hazards but it’s ok because you can just lead with volcorona :)
