I can trade Rufflet/Braviary or Tepig/Pignite/Emboar or any other Pokémon I can find in W2, actually (rather not trade a legendary though).
I have access to Pokémon Dream Radar and of Yancy's trades, I have Meowth, Wobbuffett, Ralts, Shieldon, Rhyhorn, Shellos, Mawile, Spiritomb, and Snorlax so far.
I quit the games for awhile to focus on a difficult two years of school and am just now getting back with White 2 in order to prepare for a full re-immersion with X/Y! I am trying to get every Unova Pokémon (and any else I can manage from the other regions) but I am still missing the Vullaby/Mandibuzz line!
Feel free to PM me if you're interested, thank you!
EDIT: Trade completed! Thanks EagleEye =)
