Any tips for battle tower?

As I have said before in different questions, I’m trying to get a 100-win streak in the battle tower in Pokemon pearl and I have made multiple competitive Pokemon including (but not limited to), tyranitar, scizor, heatran, raikou, starmie, kingdra, garchomp, weavile, mamoswine and more. If anyone got any tips of which Pokemon I should use and which combination I should use, please tell me, and if anyone in generation 4 has a good competetive Pokemon and could borrow me one I know a way that we can trade internationally despite the fact that the wi-fi stuff has been shut down in ds games, just tell me if you wanna trade it would be appreciated.I know it’s a long question but I’m desperate, any answers would be highly appreciated!

You can look up some strategies or use this. There is a lot of stuff over there but you can a team with a Fire type, Water type, Grass type, Electric type, and the rest is whatever you want. Maybe ground and dragon or flying and psychic or whatever. Looks like you got Legendaries so use those. Also if you can’t find something good to make the battle easier, use something like Stealth Rock and maybe have like Toxic. Hope this helped.
