I have several Pokemon I've bred recently that may interest you for the 6 IV Japanese Dittos:
Adamant Dragon Dance 5IV Charmander
Adamant Aqua Jet Pure Power 5IV Marill
Adamant Baton Pass Speed Boost 5IV Torchic
Adamant Gale Wings 5IV Fletchling
WIP: Adamant 5IV Kangaskhan
I have plenty of other Mons I recently transported from Gen V that I have not looked at and if you have any preferences I'll give them a look and you can tell me if there's that sounds interesting (Timid 6IV Hustle Nidoran, 6IV Rotom, etc.)
Thanks for the Tyranitarite, also, I'll give you a tip of how to do when you trade legendaries by GTS...get all the big ones first (Ho-Oh, Lugia), leave the ones from Unova and the members of Trios (Entei, Suicune) by last.
