No Peeta? :(
The Ferrothorn + Forretress Combo seems really rather redundant to me, and the two of them together do nothing but slow the team down substantially. Swift Swim Ludicolo
checks Kyogre and Groudon more reliably than Ferro ever could, it also benefits from the rain to a greater extent and keeps the offensive momentum ever in your favor.
You could also use the Subseed set, it really comes down to personal preference.
Now that you have a more reliable check to Kyogre, Chansey isn't really pulling its weight. In fact, the only thing I see it doing for this team is wish passing, which is hardly enough to warrant a team spot. Wish Support Jirachi
does the exact same thing, while contributing more to the team in the form of resistances as well as annoying the opponet to death :P. It also counters Mewtwo in the rain.
Of course, the decision to follow my advice ultimately lays in your hands, but dont let me push you into changing your team. If you feel that my arguments are not justifiable, then feel free to disregard my advice (Although I do implore you to at least try my suggestions, as I firmly believe that they will benefit your team) Other than that, solid team and RMT!
