Hi Byansk, I have an Riolu egg with EVS 3500.
Would you mind hatching it for me?
Exept this one I don´t have any other flawless pokémon, but I could give you an Riolu egg with 5 IV (no Sp.Att) and jolly nature.
The ESV of this one is 452.
ps: sry, my english isn´t that well -.-
greetings from germany
Nuramon
