Hmm, I'm not really that well-informed about competitive play, but I'm pretty sure in generation 4 Jumpluff is a NU, but gets used often in ubers because of Groudon. So, with Drought Ninetales existing in generation 5... Well, with the insane speed Jumpluff reaches that way and its huge annoying movepool, I can see Jumpluff's popularity rising, even with the suboptimal defensive typing. But, the real only problem I can see is Politoed ruining the Chlorophyll bonus. Ice shard I don't think as a problem of, no one would leave Jumpluff out against one of these without a Substitute up.
