Very important thing here. If we're making a special Fighter that can kill all the OU Special walls bar Vapeoreon, I guarantee it's going to be used by itself often.
Togekiss can set up on or kill every OU Special Wall, including Vaporeon and Celebi. That's not enough to make it top OU, because it still has mediocre speed and typing, suffers greatly from moveslot syndrome and can still be beaten by status. Like I said earlier, our CAP should, like Togekiss, need anti-status support to reliably beat Celebi. As long as one of the pair can do that, Blissey won't stop them.
Even if you suggest we make it have only good Special Attack unless it's passed it, you're going to have to deal with Celebi and it's CM baton passing, and I bet Celebi is also going to like having a recipient that can take U-Turns without fear and kill Ghosts.
We're intenting to make a low-OU pokemon that shines witk Kiss. Why would Celebi bother with it when it already has Celetran? Not to mention that Celebi doesn't need parlysis or anti-status support.
But if I need to use it to counter this Togekiss/CAP11 combo, then you bet your ass I can and will do it. Anything is fair game on the defense.
So now, our pair has one counter that's bad at everything else. Big deal.
no really, you did just type the same thing twice
Like I said earlier, Colossoil is the best rapid spinner ever, but not used as the best spinner ever because it can do something else even better.
Also, think about this: there is no way we can guarantee which Pokemon this CAP will be used alongside.
We can't guarantee it, but we're supposed to do everything we can to make it so ! We're supposed to try to push Togekiss higher, not making a cool pokemon that could help Togekiss, but is actually used to help Gyarados.
what other pokemon helps gyarados JUST FROM BEING A GROUND TYPE
Not just from being a Ground type, but from being a ground type and disposing of Rotom-A, Gengar, Zapdos, maybe starmie. Just like Colossoil, which is often partnered with Gyarados, not Togekiss
