Flying type. I love their spectacular and high speed attacks (not in games.. they are not represented well in games)
ghost/dark thats spiritomb and sableye. they have good stats and no weaknesses thats perfect
So. Attck is pretty good so I'd teach them powerful sp. attacks and I give them items or a move to make them faster or make it easy and and have more than one potion on hand
Or just get an action replay and make it so you have unbelievable stats lol
I haven't used an action replay since I was 8. I can't even turn on diamond now even without the machine and I had a lvl 100 empoleon. Lesson learned
I'd have to use more than one type because herp a derp.
