Definitely transferring over Latias and Cyndaquils/ Typhlosions, shiny Gyarados and Lanturn; Ho-oh, Suicune, Lugia, Kyurem, Reshiram, Cobalion, Virizion, Tornadus, and some other starters that aren't in X & Y. Debating on if I should bring my Espeons/ Umbreons over as well. I've already transferred one halfway to 100 trained pair out of HG to Black, with plans of them going into Y, I don't know if I should transfer over my other HG Esp/ Umbreon pair, since they're not only trained better and higher leveled, but I'd be losing some of my best- and only trained party members. Thankfully, I still have until the end of the month to fully decide.
