Finally.... That was a lot of writing
Please tell me how i can improve any of my teams in any way. All help is appreciated.

its an interesting type combination...but we dont exactly know the stats, ev's, or the natures...

so they would be helpfull

also, i recommend throwing a lucario in there as a sweeper, especially in competitive battling...man they can be versatile
