Need help making rest of team

So on my team so far I have mew, mega eevee, and Gyarados but idk who else to put in. Any recommendations?

Scizor can be fun, Delta Scyther, Delta Gardevoir, Gengar, Excadrill, Spidergross, and Tyranitar are all fun options.

Thx i think ill put tyranitar into the team. I can put armor on it
