Hey Guys! Here's the team I used to beat Pokemon Shield, some of the 'mons were caught in the Isle of Armor however I'm also providing alternatives. I've tried to cover for weaknesses and I feel this team is mostly airtight. I hope you like it!
1) Cinderace
Cinderace(Bugs) @ Charcoal
Ability: Blaze
Nature: Jolly
Moveset:
1) Blaze Kick
2)Pyro Ball
3) Iron Head
4) Counter/Bounce
For my starter I decided to go with Cinderace. Blaze Kick and Pyro Ball are STAB, plus they are far more preferred over moves like Flamethrower, Heat Wave etc. since Cinderace has a high Attack Stat. Furthermore, they become Max Flare on Dynamaxing which sets up the sun boosting the power of Cinderace's Fire type Moves. Iron Head is, well, a Steel type move, again using Cinderace's Attack and on Dynamaxing becomes Max Steelspike, Raising its Defense by one stage. The 30% flinch chance doesn't hurt either. Finally, you can opt for any moves between Counter and Bounce since on Dynamaxing they become Max Knuckle and Max Airstream(one which boosts Attack and one which boosts Speed respectively).
Based on this moveset,
If you choose Counter, Cinderace is super-effective against: Ice, Grass, Rock, Fairy, Steel, Dark, Normal, Bug
If you choose Bounce, Cinderace is super-effective against: Ice, Grass, Rock, Fairy, Steel, Bug, Fighting
2) Krookodile
Krookodile (Killer Croc) @ Leftovers [Isle of Armor]
Ability: Moxie
Nature: Jolly
Moveset:
1) Earthquake
2) Crunch
3) Close Combat
4)Outrage
Earthquake and Crunch are STAB again focusing on Krookodile's high Attack stat. Close Combat and Outrage are mostly used to decimate opponents if you end up in a tough spot. I used Krookdile mostly as a "Get in first and hit hard" kind of Pokemon, relying heavily on its attack and decent speed.
Based on this moveset,
Krookodile will be super-effective against: Fire, Electric, Poison, Rock, Steel, Psychic, Ghost, Normal, Ice, Dragon
OR
2) Excadrill
Excadrill(Holy Moley) @ Leftovers[Galar Mine 1]
Ability: Sand Rush
Nature: Jolly
Moveset:
1) Earthquake
2)Iron Head
3)Rock Slide
4) Swords Dance
Earthquake and Iron Head are STAB moves, and focus on Excadrill's High Attack. Use Swords Dance in the beginning to boost the attack even further. Rock Slide is to mostly provide additional coverage to Excadrill and deal with the those pesky flying types while you're at it
Based on this moveset,
Excadrill will be super-effective against: Fire, Electric, Poison, Rock, Steel, Fairy, Ice, Flying, Bug
3)Blastoise
Blastoise(Tsunami) @ Choice Scarf [Isle of Armor]
Ability: Torrent
Nature: Modest
Moveset:
1)Water Spout
2)Surf
3)Ice Beam
4)Dark Pulse
Water Spout is its strongest move, boasting a 150 Base Power when Blastoise is at full health. Thanks to the Speed boost it gets from Choice Scarf, it can outrun even Timid or Jolly Dragapult! Surf is a weaker but more reliable Water-type STAB for late-game matches and if Blastoise has already suffered some damage. Ice Beam and Dark Pulse provide coverage.
Based on this moveset,
Blastoise is super-effective against: Fire, Ground, Rock, Grass, Flying, Dragon, Psychic, Ghost
OR
3)Gyarados
Gyarados(Tidus) @ Sea Incense
Ability: Moxie
Nature: Adamant
Moveset:
1)Earthquake
2)Waterfall
3)Crunch
4)Outrage
Waterfall provides STAB, Earthquake deals with annoying electric types, the only real danger to Gyarados, Crunch and Outrage provide coverage. Use Outrage to wreak havoc on your opponent thanks to Gyarados' high attack!
Based on this moveset,
Gyarados will be super-effective against: Electric, Fire, Ground, Rock, Poison, Steel, Psychic, Ghost, Dragon
4)Hawlucha
Hawlucha(El Bravo) @ Expert Belt
Ability: Limber
Nature: Adamant
Moveset:
1)Flying Press
2)Iron Head
3) X-Scissor
4)Dual Wingbeat/Fly
Hawlucha has been my favourite fighting type since Pokemon X and Y and even in Sword and Shield it doesn't disappoint. Flying Press, its signature move and Dual Wingbeat/Fly provide STAB, Iron Head provides coverage and has a 30% chance of flinching and X-Scissor helps against those annoying Psychic types.
Based on this moveset,
Hawlucha will be super-effective against: Normal, Ice, Rock, Dark, Steel, Grass, Fighting, Bug, Psychic, Fairy
5) Galvantula
Galvantula(Zippy Zap)@ Magnet
Ability: Compound Eyes:
Nature: Timid
Moveset:
1)Bug Buzz
2)Thunderbolt
3)Energy Ball
4)Thunder
There isn't much to choose among electric types and Toxtricity, Boltund is fairly common. I chose Galvantula as its Compound Eyes ability makes Thunder much more accurate and it's additional bug typing negates its weakness to the fairly common Ground type. Besides, Bug Buzz and Thunderbolt provide STAB and Energy Ball allows you to hit any Rock types that you may find yourself against. Just watch out for Fire.
Based on this moveset,
Galvantula is super-effective to: Water, Flying, Grass, Psychic, Dark, Ground, Rock
6) Dragapult
Dragapult (Speedy) @Life Orb
Ability: Clear Body
Nature: Jolly
Moveset:
1)Dragon Darts
2)Dragon Dance
3)Phantom Force
3)Psychic Fangs
The nickname accurately summarizes the latest pseudo-legendary. It has amazing Speed and Attack which is further amplified using Dragon Dance. Dragon Darts and Phantom Force provide great STAB, Psychic Fangs is mostly for coverage.
Based on this moveset,
Dragapult is super-effective against: Dragon, Fighting, Poison, Ghost
