I just noticed that manaphy is getting friggen UU usage, again. This is unacceptable. What special attacking setup sweeper do poeple use instead of manaphy? I know thundy gets a lot of use (no surprises there, pretty good mon), but is thundy really the only special setup sweeper? There aren't really a lot of NPers in OU tho besides thundy (most toges I see are either scarfed or defensive paraflinch). There are a few CMers like clefable and sometimes keldeo (manaphy > keldeo imho, but they are two rather different mons). Any suggestions?
Sorry to break that to you, but if Manaphy is the second best special sweeper the metagame can offer, then special sweepers suck. People are just moving to physical sweepers, because they outclass Manaphy badly.
This thing is just overrated in my opinion. It just doesn't have enough speed to sweep, and it's attack power before the Tail Glow is pathetic, so it's not really a team player. It's very one dimensional, it pratically requires Tail Glow to function, and it can be easily countered if you predict the obvious Tail Glow, due to its low speed and lack of priority. I know it also has a defensive set that is viable, but the defensive set is not that great to make it OU.
It's a beast on rain teams though, I'll give it that.
But in the end, I think everyone has tried to use Manaphy once, realized it's just underwhelming, moved to something else and never touched it again. It's been months since I was last swept by it. It has simply disappeared from the ladder.
