Help Fix My Gen 8 Team

Question

Blacephalon @ Leftovers
Ability: Beast Boost
EVs: 252 SpA / 6 HP / 252 Spe
Timid Nature
- Mind Blown
- Shadow Ball
- Solar Beam
- Expanding Force

Coalossal @ Power Herb
Ability: Steam Engine
EVs: 252 SpA / 6 HP / 252 Spe
Modest Nature
- Protect
- Meteor Beam
- Flamethrower
- Scorching Sands

Indeedee-F @ Eject Button
Ability: Psychic Surge
EVs: 252 HP / 6 SpD / 252 D (*I was prepping her for a TR team at first... might need to redo)
Relaxed Nature
- Follow Me
- Protect
- Energy Ball
- Expanding Force

Alolan Raichu @ Choice Specs
Ability: Surge Surfer
EVs: 252 SpA / 6 HP / 252 Spe
Timid Nature
- Thunderbolt (considering Discharge...)
- Fake Out (maybe "Ally Switch instead?")
- Surf
- Expanding Force

Grimmsnarl @ Light Clay
Ability: Prankster
EVs: 252 HP / 6 D / 252 Atk
Adamant Nature
- Light Screen
- Reflect
- Spirit Break
- Sucker Punch

Garchomp @ Life Orb
Ability: Rough Skin
EVs: 252 Atk / 6 HP / 252 Spe
Jolly Nature
- Earthquake
- Outrage
- Swords Dance
- Iron Head

Ideas:
1) Blacephalon's Mind Blown could activate a G-Maxed Coalossal's "steam engine" on top of doing big damage to the other team, and then Coalossal could drop a strong G-Max Volcalith from the Meteor Beam (I have Power Herb on him just in case I have to use that Meteor Beam when not Maxed)...
2) Blacephalon gets Expanding Force, so I thought I could pair him with Indeedee sometimes for a double hit of that (she brings the terrain).
3) Alolan Raichu also gets Expanding Force and he can be a second redirection guy with either Fake Out or Ally Switch... I really like Ally Switch; but I'm not sure which is best to put on him (or do both, and just lose the Surf, which was for coverage and for possibly activating Coalossa's steam engine another way).
4) If I put Discharge on Raichu, then Garchomp could be out there and be immune to it, while it damaged the opponent. But, in any case, I like Garchomp as a strong attacker on this team, with Swords Dance while Raichu or Indeedee do redirection...
5) Grimmsnarl's purpose seems pretty obvious.

Moves like Solar Beam on Blacephalon and Energy Ball on Indeedee are just for some coverage against Water and Ground types... I dunno. Lol. I'm very new to this. Any help would be very much appreciated!

Thanks,
M

Comments

Usually Steam Engine Coalossal runs a set with Weakness Policy and something else that has Surf activating both Steam Engine and Weakness Policy to sweep. Just thought I should mention that Fake Out doesn't work in Psychic Terrain so consider changing that, especially on a Specs set. Grimmsnarl could probably consider running Thunder Wave instead of Sucker Punch. Outrage is very bad in Doubles because you don't get to choose the target. Dragon Claw, Scale Shot, or Draco Meteor are better options. Garchomp also doesn't really need Iron Head. Earthquake is kinda bad for your team since half of it is weak to Ground, but you could try replacing Indeedee with a Flying-type or Levitator.
