Wait, people NAME their Pokemon based on IVs? That just seems stupid considering you have 6 markings you can use on every Pokemon. The markings are even searchable in the PC, making it very easy to find the correct Pokemon with specific IV-spreads.
I've traded away a lot of reject Joltik, Abra, Gastly and Dratini, but I only seem to get crap. Other than crap I have gotten Protean Froakie, HA Fletchling and adamant huge power Marill with Belly Drum+Aqua Jet. But none of those Pokemon are useful to me, since I already have them (near) flawless.
Well there's no good way to mark that the Pokemon has 30 or 0 of a certain IV, which is still useful. I just named some of my ditto 30 [stat] so I know what they have for Hidden Power breeding. Though, I don't see the point of naming the Pokemon something specific for 31's.
I traded a lot of my breeding rejects for a bunch of other breeding rejects. One of which was a 4IV Japanese Clauncher that my brother used to get a 31/1/31/31/31/22 shiny one.
