Hey man, I got the Cherubi hatched! I do have one nitpick though, I hatched it in the Goldenrod City Flower Shop, and it only says Goldenrod City on the Egg Hatched location..
I don't have an AR, so I can't check exact IVs, but I went to the Battle Tower and it has outstanding potential and the 31s in HP,Attack,Defense and Speed as you requested. Then I went to the Celadon Game Corner and the guy said it's HP would be Ground.
