Guys, I need advice on how to beat my bros in a casual tournament without looking try hard. The tournament rules say: NO items of any sort (including held) and no legendaries or psuedos (nothing that there is only one of)

I have chosen UImbreon special tank/stall, Gliscor physical tank/stall and Electivire physical sweeper. I am aware of Electivire's not being very good but I fucking love that guy and I have never used him. I figured a casual tournament with bros is a good chance to.

Does anyone have specific suggestions or advice for me?
