[DISCUSSION] Need help for My M-Sceptile VGC team

[DanielJames]

It looks like a solid start, but I do see huge opportunities for growth though. Why are you using a Sassy natured Groudon? Are you going for a team that can operate in Trick Room? If that's the case, then Sceptile doesn't work here. Also, Stealth Rock is a bad move in VGC. I'd also use Precipice Blades over Earthquake because not only does it hit harder, it doesn't hit the Pokémon on your side either. I'd also use Eruption over Lava Plume for similar reasons. This is the Groudon I run:

Groudon @ Red Orb
Ability: Drought
Level: 50
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Eruption
- Flamethrower
- Earth Power
- Protect

Similarly, if you wanted to run a physical attack Groudon, you can run an Adamant/Jolly nature with 252 in Attack and Speed with Precipice Blades, Fire Punch, Rock Slide/Dragon Claw/ any other coverage move, and Protect.

Rotom-W was a great Pokémon in VGC last year, but I don't know how it stacks up against top threats this year. It gets completely walled by opposing Groudon which is the most used Pokémon in the format.

Sceptile is too frail to use. If you're using it to counter Kyogre, you'll get just wrecked by a 4x super effective Ice Beam. Talonflame, another common threat, will Brave Bird it into oblivion.

I would swap Rotom out with Kyogre and run a Double Primal team. If you want to run M-Sceptile because of it's ability then maybe run a Thundurus with Discharge? Thundurus has way more utility than Rotom, being able to get off Prankster Taunts and Thunder Waves for speed control.

So here's how to team would look after my changes:

Groudon @ Red Orb
Ability: Drought
Level: 50
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Eruption
- Flamethrower

Level: 50
EVs: 4 HP / 252 SpA / 252 Spe

Sceptile @ Sceptilite
Ability: Lightning Rod
Level: 50
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Leaf Storm
- Giga Drain
- Dragon Pulse
- Protect

Thundurus @ Focus Sash
Ability: Prankster
Level: 50
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Discharge
- Thunder Wave
- Taunt
- Protect
