Things with Bank-required egg moves do well. Heat Wave Litwick was my all-star, and since I've been trying for a Masuda shiny I had a ton of extra 5IV ones, so unlike most of what's on the GTS I actually put up what I said I had. Using those to get low value legendaries and trading up from there, I was able to get the Shiny Charm today.

I'll deposit a couple of legends later tonight looking for Blissey and other hard to evolve Pokémon for my Dex.
1. Get a Chansey. 2. Get Kelpsy/Hondew/Qualot berries (assuming you just want Dex data); feed Chansey until the Att. is unable to be lowered (best to do before you level up). 3. Equip a Soothe Bell while Chansey is your lead Pokemon. Ride you bicycle in Lumiose Prisim Tower loop-lap. 4. wait for the profit. 5. Profit and GTS for another Trainer.
