Here's a team of sweepers I created. I'll assume it's Gen 8 NatDex, like the previous answer.
Zeraora @ Choice Band
Volt Absorb
Adamant
252 At and Spe, 4 SpD
-Play Rough
-Plasma Fists
-Close Combat
-Outrage
Standard, but works well. If threatened by a Ground type, switch to.....
Hydreigon @ Life Orb
Modest
Levitate
252 SpA and Spe, 4 SpD
-Surf
-Dark Pulse
-Draco Meteor
-Nasty Plot
Again, pretty standard. Hydreigon has an amazing moveset, so any moves can be substituted with Flash Cannon, Flamethrower, Earth Power, or the like. If threatened by a Fairy, switch to.....
Aegislash @ Weakness Policy
Adamant
Stance Change
252 At, 128 Def and SpD
-King's Shield
-Swords Dance
-Shadow Sneak
-Iron Head
This one is a bit of a mixed bag. It also has Sacred Sword as another coverage option. If threatened by a Dark type, switch to....
Xerneas @ Power Herb
Timid
Fairy Aura
252 SpA and Spe, 4 SpD
-Geomancy
-Moonblast
-Psyshock
-Thunderbolt/Focus Blast
Xerneas with Geomancy and a Power Herb is still a beast. If threatened by a Steel type, switch to.....
Arcanine @ Lum Berry
Jolly
Flash Fire
252 At and Spe, 4 SpD
-Flare Blitz
-Outrage/Wild Charge
-Extreme Speed
-Morning Sun
This is one of my favorite sweepers. Flare Blitz and Wild Charge recoil can be healed with Morning Sun. If threatened by a Water type, switch to......
Ludicolo @ Damp Rock
Modest
Swift Swim
252 SpA and Spe, 4 SpD
-Rain Dance
-Hydro Pump/Surf
-Giga Drain
-Ice Beam
So that's it. The team has 3 Special sweepers and 3 Physical ones. I tried to have a major weakness of one sweeper be resisted by another one. Other than that, they're pretty much each their own individual thing. Please comment any suggestions.
