I actually took the time to set aside I think five boxes worth of WT pokemon, with two from each of the first two starting digits of ID numbers (00 - 65). As such, I've never had a day where I've won less than the PP Up, and my odds on the PP Maxes have so far been relatively kind to me. As a result, I literally released some eight boxes of WT pokemon, most of whom were either early route stuff from early on when I traded, or else bred pokemon that simply were outclassed by others I had either received or bred for myself. I still manually check all of what I receive, and every so often it provides something very useful, but now given the extent of what I'm breeding, I've covered a lot of the commonly bred stuff. And there are still days when I have gotten what look to be great pulls to come up rather lacklustre. That being said, I'm still trading out all my breeding excess because it may prove beneficial for someone down the line, it accumulates sweet Pokemiles, and continues to uphold the general upward trend of good stuff in the system.
As such, I'm soon about the do two boxes of Togepis and a box of Chespins. Here's hoping for a 4IV Female Chlorophyll Bulbasaur!
