Do you not still have the one that roams in the wild available? It's a pain in the butt to do, but the roamers can be RNG'd.I want to RNG abuse a 4th gen Latios/Latias to have access to defog + good nature and IVs. But since they were from a Wi-fi event you can no longer get the Enigma stone. Is there a way to reproduce this event in a physical copy of the game? Or is there any other way? ...
Likewise, I think you could use PowerSaves to inject the Soul Dew Wonder Card into your game, if you've got that. Just be sure to disclose this if you go about trading the Lati@s.
Or just look through the trade threads for a Defog Lati@s and see what they want for it.
