to be onest it depends raqauza is very strong even though it's out rage is good it's a pain in the neck but you can still teach it great tm's and giratina's origin forme and alter form are great and his shadow force is amazing but the problem is it has low pp and can only hit one pokemon at a time.don't waste your time with mew or mewtwo though. i'd have to say either out of raquaza cause of it's intense attack stats,giratina because of it's good stats and ,mind blowing shadow force,dialga cause of it's handy raor of time which is great and his k stats or shaymin because he has a move that heals all your pokemon which are effect by stuff like poisin,sleep,confusion and maybe darkrai cause of it's dark void which is unbelievably useful but only for one pokemon but darkrai lacks stats
