Common sense is also quite handy with competetive. If there is a pokemon you like the look of. Look it up on Bulbapedia
It'll give you a break down of:
base stats Level of evolution (if any) Level up move pool
Which moves are aquired from: Breeding Move tutor Previous evolutions Events
This is a very handy way of assessing what type of pokemon you could make your target into. I.e. if its got high speed and sp.atk & atk. With a good variety of attacking moves in both physical and special spectrum. It could become mixed, or choose to specialise in one or the other.
But as others have suggested. Smogon is great for ideas. But i strongly suggest experimenting. Cookie cutter teams are good. But very VERY predictable. --- Black FC: 2666-8397-4718 Author of the Starfox Story on the Starfox Assault board. Check it out! Don't Fear the Reaper
