I gave you scans this time. I know that you can't give a great ruling on this until Hydreigon from Dragon set comes out, but your best opinion is good enough.
If I have a DCE attached to Hydreigon NV, can I move it to another Pokemon because of Dark Trance and Dark Aura. DCE would become Dark Type, and since the scan for Hydreigon Dark Trance doesn't limit to Basic dark, can I move it? I know If I move it to, say, a Tornadus EX, I can't move it back. I can only keep swithcing the DCE between Dark Aura Hydreigons.
