So, I am currently EV training the last poke of the 6 I'll use for the VGC. However, it just now occurred to me that I may, in fact, have a serious problem on my hand...or not...
2 of my pokes on my team were bred from parents that were both from random people on the GTS and I got 1 white herb from there too. I don't know if they were legitimate or not!!!
I've never used a "Gameshark", "Pokesav", or whatever on my DS, or my cartridge, and I've never used the GTS on my Platinum cartridge. The parents stats and moves were all in order. All the breeding and trading took place on my Pear cartridge. Every single poke on my Platinum cartridge was caught in Platinum, or bred by me in Pearl and then traded to Platinum from 1 DS to the other.
Do I have any reason to worry about the 2 pokes that I bred whos parents were of ambiguous origin?
Do I have any reason to worry about the 1 White Herb that is of ambiguous origin?
I'm just concerned that I'll actually get to the finals and be disqualified because of 1 shifty item and 2 pokes with shifty parents?!?!?!?!?!
I'm fairly sure you'll be fine. The only thing children obtain from their parents is IVs, nothing more. Hacked parents won't cause the children to appear as hacked.
