Im not the best at making teams, so when you have it, test it a little bit add or take a Pokemon, change moves, etc.
Here's what I would do:
Absol/Gardevoir(depends which one you are better with)
Camerupt
Sceptile
Starmie
Manetric
Skarmory/A normal/flying type/Aron(sorry, can't help you with this one, they are all good!)
Once again, do what you want! That is only a one team. There are so many! One thing you could do is get a salamence in the last position.
Those are all very good Pokemon.
Tip: Try to keep all your Pokemon the same level. Send one out first until it is a level in the increments of 5, or 2, or something, then switch the first Pokemon with a lower level one. Eventually, they should all be level ___ and then you can do a new round.
When I try to build teams, I try to at least get a fire type, grass type, water type, and a flying/something type.
Hope I helped!
