I thought of this team yesterday and tested it out on Pokemon Showdown and so far I think it works pretty good but I'd like to hear some opinions or suggestions. This isn't really a Trick Room team but I do set it up when I think it would benefit me more but it works great regardless.
1.) Togedemaru @ Focus Sash
Nature: Jolly
Ability: Iron Barbs
IVs: 0 Sp.Atk
EVs: 252 Atk / 252 Spe / 4 Def
-Zing Zap
-Fake Out
-Encore ( I'm thinking of switching it out for U-Turn or Nuzzle , but I did have a few battles where it came in handly)
-Spiky Shield
*I was thinking of running Lightning Rod on either Togedemaru or Marowak but I didn't think they benefit me much and I thought I didn't need them since my opponents don't usually risk going for any lightning attacks.
2.) Alolan Marowak @ Thick Club
Nature: Impish
Ability: Rock Head
IVs: 0 Sp.Atk
EVs: 216 HP / 94 Atk / 180 Def / 20 Sp.Def
-Will-O-Wisp
-Flare Blitz
-Shadow Bone
-Rock Slide
*I thought Cursed Body would benefit me more but there's only a 30% chance of it activating, it's worth it when it does but I chose Rock Head for Flare Blitz since the recoil damage.
3.) Bewear @ Expert Belt / Choice Band
Nature: Adamant
Ability: Fluffy
IVs: 0 Sp.Atk
EVs: 252 Atk / 248 HP / 8 Def
-Hammer Arm
-Ice Punch
-Thunder Punch
-Wide Guard ( Thinking of replacing it with Earthquake or Shadow Claw)
4.) Alolan-Exeggutor @ Sitrus Berry
Nature: Quiet
Ability: Harvest
IVs: 0 Spe
EVs: 212 HP / 252 Sp.Atk / 46 Sp.Def
-Dragon Hammer (Chose Dragon Hammer over Draco Meteor because of -2 Sp.Atk Drop)
-Flamethrower
-Giga Drain (Chose Giga Drain over Wood Hammer because of recoil Damage)
-Trick Room
5.) Primarina @ Assault Vest
Nature: Calm
Ability: Torrent
IVs: 0 Atk
EVs: 252 Sp.Atk / 168 HP / 88 Sp.Def
-Ice Beam
-Scald
-Psychic
-Moonblast
*I wanted a bulky Water Type and Anti Dragon pokemon on the field, although I think Tapu Fini or Lele would be a better replacement.
6.) Garchomp @ Life Orb
Nature: Jolly
Ability: Rough Skin
IVs: 0 Sp.Atk
EVs: 252 Atk / 252 Spe / 4 Def
-Swords Dance
