Oh, forgot you mentioned Umbreon, too.
Umbreon has a variety of spreads you can use for it, as well as a decent variety of moves it can use, despite the fact that it was only popularized off of a single good set. Much like Cresselia, Umbreon has really good raw bulk that allows it to do essentially whatever it wants. What separates it from Cresselia, however, is the fact that the moves it gets are much better at taking on meta threats.
While Umbreon is only known for the original Lost heros set, it only really needs a recovery move (Moonlight/Wish/Rest?), and ends up having 3 slots to set up its win. Its possible moves for those 3 slots can be anything between Charm/Foul Play/Snarl/Taunt/Toxic/Baby-Doll Eyes/Curse/Payback/Growl/Spite/Bide. That said, this is pretty much all speculative based on sets that either don't exist or aren't overly used, so I suppose it would be fair to drop Umbreon's Flexibility from 8 to 7.5 or even 7
