Need PVE pokemon team

[Keseko]

Hello everyone, so basically my request may be absurd or something i want a pokemon team especially for PVE that can beat all e4 across regions and can carry against some hard trainer battles

now i have completed all regions and unlocked all areas but the thing is am not really that strategic of a person and i really am not capable of finding the perfect team to counter anything, it doesn't need to be perfect just good enough to carry me across all regions since i don't care about pvp there is a chance all of this is not possible but i want to see the available options,

Thanks for reading.
