Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Hhhm weird, it keeps saying there is a problem with this Pokémon. My ditto is legit cause I did RNG it and traded it in the gts in 6th gen before, let's try direct trading
Apparently all my RNG's has a problem. Sorry for wasting your time, I'm going to see how to fix this. You will get that ditto, I might even give it to you in 6th gen if I have to
I guess what Xen said is the problem. Thank you for your kind words. However, you're still getting that ditto. If you can put something up in 6th gen, it can be easily transferred over to 7th gen through bank. Up to you though :)
