I wonder if Insomnia/Vital Spirit as Cresselia's levitate stand-in thing would be interesting; a sleep immunity would certainly fit her theme as Darkrai's counterpart, and wouldn't lack utility at all. I suspect if this actually happened she'd be more likely to get a signature ability but either of those would work just as well.
(I also ponder if Darkrai should have levitate but ehhhhhhhhhhhhh)
