Since you posted the reply on your page, I only now just saw it with no alert.
All three of those I could use. You don't have to trade originals, bred ones are fine. If you want to do that, we have a deal for any three Black-exclusive Pokémon. (I'll double-check on Oddish, but Rhyhorn and Shinx I am sure I do not have.)
I still have to do D/P/P and am going to import anything missing from there someday (SS too, which I'm through four badges on), but am doing the Pokédex in the meantime independent of those projects. Once I have Pearl and Platinum done (I say both because I'm going to swap Pokémon back and forth to increase the experience gaining potential), I'll use the DS Lite with its game to import to Black. From there, if I ever want to import to Black 2, I'll probably be getting White used to hide out on the DS Lite, use the Union Room to move babies around, and then finally import some to Black 2.
What White Forest Pokémon do you have or want? Keep in mind I have Black, so my White Forest collection is very small. If you have a huge number of Pokémon I could use, we should plan a trading session just for us and I can breed some Eggs of various types to trade.
Also, I think there's a GTS in Unova; why not put some Vulpix up there and try to collect Pokémon you're missing? I'll set up a trade with you for Vullaby and Gothita; I actually have a Gothita with Miracle Eye bred by me personally that is literally still a newborn (Lv.1) that you might like. Miracle Eye makes those Psychic type moves have an effect on Dark-type Pokémon like Purrloin. I'd like something unique that I might not yet have, particularly if it can't be caught anywhere in Unova, though I also need some White Forest exclusive Pokémon (a lot of them, in fact). I also have a pair of Vullaby that know Roost and have Air Slash early.
Well, I already got a Vulpix...I've caught all the land-based Pokémon in every area; I forgot to count Village Bridge before, but I corrected this today and Seviper - which didn't stay in the ball on R11 - finally stayed put after I fought it to submission with weaker opponents and lost two of them. I'm currently in the Undella area surfing and fishing, and I have Remoraid on my search list, among others. I've also read that it must be in the party for another Pokémon to evolve; I found that interesting. I will check the water in Route 14 later on Bulbapedia, but there may only be a couple to find at best. I did finally get the Lapras from Village Bridge (5% encounter rate with 95% Basculin in Surf Spots).
What do you have on the National Dex that I might be missing? I'll someday be importing beauties from other games, but for now, I'm trying to trade for whatever I can that I need. Someday, I'll need my own Action Replay and clone the legendaries I have, putting them up for trade seeking other legendaries; however, I will be localizing the search for rarities like Jirachi to this forum. I actually executed a trading plan involving some clones in my direction that should cover most of the ones I would have been missing, but there are still a few I'll figure out over time.
What are you missing from Unova's Dex? I assume it's a version exclusive, being either Gothita/Vullaby (Black) or Solosis/Rufflet (White), not counting Cottonee/Petilil (also exclusives, but you can trade for one in Nacrene as well). If it's anything else, I can help; I have the entire Dex completed except for the legendaries not yet officially released (Meloetta, Genesect).
If what you're missing is a legendary, I can't trade those unfortunately, but if it's anything breedable (495, which is Snivy, to 637, which is Volcarona), let me know. I'm sure we can work out something.
