Need help with hold items for this team in the upcoming VGC!

[help me finish] I'm only entering this comp to get the two mega stones so the team I'm using is the IG team that you guys helped me come up with.

Since i just need to do three battles to get these mega stones this team just needs to be able battle 3 times, but i will use all the battles just for the fun of it as see just as far this team can go.

Ik that is team will be wrecked by earthquake, and that this is NOT THE BEST COMP TEAM BUT I DO NOT HAVE ENOUGH TIME TO BREED AND TRAIN UP ANOTHER ONE BEFORE REGISTRATION ENDS!

So here is my team, since i have not beat the Pokémon league yet i can not power level so I'm not sure if i have time to breed a new team plus get these Pokemon up to 50 before registration ends.

Also I'm soft resetting lunala for the correct nature and ivs through a iv calculator ( can not check ivs myself till i beat the pokemon league) so i will not be able to even try getting the tapus in time.

So here is my team:

1. Mudsdale@figy berry Ability: Stamina Evs: 252 HP/252 atk/4 def Impish nature • Close combat • Heavy slam • High horsepower • Protect

2. Incineroar@choice band Ability: Blaze Evs: 4HP/252 atk/252 speed Jolly nature •Darkest lariat • Earthquake • Flare blitz • U-Turn

3. Decidueye@leftovers Ability: overgrow Evs: 252 HP/252 def/4 sp def Careful nature • Energy ball • Roost • Substitute • Toxic

4. Kommo-o@Fightinium Z Ability: Overcoat (HA) Evs: 4 def/252 sp atk/252 speed Modest nature •clanging scales • Flamethrower • Focus blast • Protect

5. Primarina@assault vest Ability: torrent Evs: 4 HP/252 sp atk/252 sp def Modest nature • Blizzard • Energy ball • Hydro pump • Moonblast

6. A-raichu@Life orb Ability: surge surfer Evs: 4 def/252 sp atk/252 speed Timid nature • Protect • Psychic • Thunderbolt • Volt switch

Again Ik this team is not very good but i do not have time to make breed another or try catching the tapus since I'm soft resetting lunala.

I just want the mega stones so I'm not trying to win, just want to be able to win as many battles with this team as possible. ( IK it may not be a lot or any at all)

I just need some help with what hold items to give them.

Thanks for the help😊
