This is my third time trying to respond to this so forgive me if I sound jaded.

If you'd like a royal road to team building I would recommend just ripping a team off of https://trainertower.com/

Ya I'm not going to build your team for you, but if you try building one on your own I'll help you make adjustments & improvements to it.

We still need the moves, natures, EVs, items, and abilities for each Pokemon. Those are important, you know.
