I agree with MoltenKyurem. Since when does Aerodactyl get either of those moves? I agree with you for the most part on the rest though. Xatu and Charizard definitely appear poised to have an impact down here. I also don't think either Sawsbuck or Victreebel are ever going to see the light of day. The first has a ghost and grass immunity over other grass types, but it's speed is only normal outside of sun and base 100 attack doesn't make it really stand out that much either (might make a good Quagsire partner though). The second just stinks outside of sun. I'd say the only way it stays out of NU is if it suddenly becomes an integral part of OU's weather wars. However, I do have some disagreement regarding Cofagrigus, who I don't think we can completely count out due to Spiritomb's emergence. Cofagrigus actually has higher defenses, though Spiritomb's dark typing may give it the edge. I also have some reservations that Sigilyph is going to have as big an impact as it might seem at first. Sigilyph has an awesome ability in magic guard and could become a major staller with its immunity to everything passive. However, I think there is also a good chance it might suffer from possessing the same typing as Xatu. I'm sure it's not the only reason for its lack of usage, but I believe something similar may have happened with Mandibuzz. Sure it is great defensively, but why use it when Honchkrow is out there. Sure they serve different roles, but when one is used on so many teams the number of potential places for the other decreases. It could end up not turning out this way, but I have a feeling the tier might end up only having room for one top-tier Psychic-Flyer.
