I made this team using Rotom-Wash, which is a good partner for what the team is focused on, an offense focused on Lucario and Gyarados, using teammates that help it to work properly.
I have tested this team and it really perfoms well against balance and offense style teams, it can suffer vs things like metagross agility but it can he stopped correctly.
Explaining a bit the team, Azelf is a great lead for what the team is focused on, doing basic things like putting the necessary stealth rocks, Tyranitar has that set to be able to cope vs things like Gengar that can threaten with focus blast and generally help well vs special attackers, rotom servers as an anti spinner that also helps vs Lucario and Machamp, also being our speed control, Gyarados serves to counter physical attackers in general and is also good to counterattack at a certain point in the game, finally Latias which is also another fight resist and generally makes good core along with rotom, to finish is Lucario, which is our win condition and is a very aggressive physical attacker.
