EVs: 6 HP/252 Atk./252 Spe
~Rock Slide

This is my lead as many of my other leads were too slow and couldn't really hit as hard as the CB'ed version of Aerodactyl. I chose Rock Slide over Stone Edge as it has more accuracy and the flinch chance is also nice whereas Stone Edge has less accuracy but more power and no flinch chance. Ice Fang is for Grasses that would somewhat wall this set such as Meganium and EQ is for more coverage. A dilemma arises between Fire Fang and Pursuit as the AI doesn't switch Pursuit would only be useful for Ghosts and Psychics but, Lucario already covers them so I'm guessing I'm going to choose Fire Fang as it offers a flinch/burn chance which could be somewhat useful when facing those major threats such as Garchomp or Tyranitar but I'd use Ice Fang and Earthquake respectively. Aerodactyl also offers a nice Ground immunity for Lucario and some other helpful resistances such as to Fire and Fighting although Aerodactyl can't really do much back to the Fighting pokes except hit with either the Fangs or possibly Earthquake.

I chose Lucario to have a somewhat fast and hard hitting special sweeper on my singles BT team and thanks to his typing he resists a lot of types that other special sweepers such as alakazam or gardevoir would'nt be able to. Paired up with Aerodactyl on the same team he's virtually unstoppable except by physical walls such as Snorlax, in particular the Cursing Snorlax in the Battle Tower, the only way this team would deal with him would probably be me hitting him with Lucarios' Aura Sphere as stated in the analysis his Aura Sphere is powerful enough to 2HKO Blissey.

I decided to change Gliscor with Garchomp from reading some suggestions of some posters and I think this is my best option at having a potent sweeper in the Battle Tower. Although I don't know which item to go with, Life Orb for more power but 10% off my health after every attack that lands or Yache Berry that can only be used once in the battle and weakens one Ice attack for more survivability but since I already have an Ice resist in Lucario I think I will go with Life Orb.
So that's my Singles Battle Tower Team that I just constructed today so please feel free to rate it as thoroughly as possible, PLEASE!
