One question: are we allowed to trade version exclusives from the other versions when we reach the spot where the pokémon is available in the other cartridge? That would really help with Skarmory and Honchkrow.
I'll do Flying because there are so many dual-types. However, my Gold and Crystal cartridges are dead, and I lost my Silver many, many years ago. I may use a ROM without hacking, I may look for one in stores or I might ask for one for my upcoming birthday. Who knows? I'll restart my Sapphire because that thing is absolutely cluttered with hacked pokémon. I'm pondering doing Platinum rather than Pearl even if my Platinum file would be gone because I can do Gliscor then.
Blue planned team: Charizard, Gyarados, Aerodactyl, Dragonite, Scyther, Golbat
G/S/C planned team: Gyarados, Dragonite, Crobat, Skarmory/Mantine, Pidgeot, Xatu
Sapphire planned team: Gyarados, Crobat, Skarmory, Tropius, Salamence, Altaria
P/Pt planned team: Gyarados, Crobat, Vespiquen, Honchkrow, Gliscor, Drifblim
Pearl/Platinum would be a hard one. There aren't too many Flying-types.
Anyway, I'm almost at Oak's lab in Blue. Yay for progress.
