Nothing in particular right now, though I eventually want to make myself a Japanese language dex, so being able to get the legendaries without needing to give up any in exchange would be nice (+now that I'm thinking about I believe I actually did fill in my living Japanese dex of the new X/Y Pokemon outside of the legendaries and Phantump/Pumpkaboo, because screw them and their uncancelable evolutions.)
A lot of the bank legendaries out now are mostly Japanese, but some are Korean. There are a couple of English ones too. From what I've been reading, they're getting harder to get.
I chain traded to get a number of bank legendaries, but I'm not sure if my method still holds up. People are saying Porygon-Z is where it's at right now. So maybe...
1. Breed Elgyem, Darumaka, or Baltoy
2. Trade for Rhyperior
3. Trade for Milotic
4. Trade for a legendary bird
5. Trade for a Swords of Justice (-Keldeo)
6. Trade for Porygon-Z
I'm not sure if it'll work. I've stopped refining my method after I completed the dex.
Should I even bother with any speed evs for gliscor? Or just straight 252 sp.d?
It depends, but my Gliscor's been doing great without any speed investment. Also, why SpD?
