Dream World Sableye

[Lost Seraph]

Now...I've gone through all the steps to make a legal (other than the fact that he's unreleased) Sableye. I want to know if it's a failure to create a good Sableye on my part, or if unreleased DW Pokemon are just universally banned from Random battles over Wi-Fi that is causing my black version to go "There was a problem with your pokemon" every time I try to do anything with him.

Here's the pkm in case you need it.
