If you had to pick a team based on the same type to win as much as possible, which type would you choose?

I'm thinking Dark as they're versatile and have good moves that can throw people off such as taunt and knock off etc.

Then of course theres steel which is strong overall but their weakness is generally the most popular sort of pokemon and moves.

Then there's Water which seems to be well balanced with simple weaknesses but ways to get around that.
