Dark Energy does work, and has its merits. However, I don't really see the room for both of them, and Ultimate Buddy can protect Demios from being bounced by Magical Goodbye and other Magic World cards. Katana World can do that too, now. Plus, it removes any potential issues Demios can have with monster's with high defense, saving sideboard room for other things.
