I'm personally using the DE Deluxes for: Slicer, Slipstream, Makeshift and Ghostbug. (the latter two being characters I've sort of made up) who are a team put together by Megatron to steal some kinda thingy-ma-bob from the Autobots, and only they can do it, due to their Dark Energon experimentation leaving them somewhat out of phase with reality. Not quite a Transwarp shunt, but enough to give them "walking through walls" and other weird powers.
(yeah, I think too much about silly gummi repaints)
