Ummmm... it's been quite a while since I've done walker abuse, but IIRC you can do something to change the nature, either "re-connect" and each time it advances the nature forward or something. If you ask in the RNG help thread I'm sure someone will know off hand.

Also, the Deoxyses don't need EVing at the moment! :p
My PC is literally full to the brim,, xD
