IMO, Kyurem-B is kinda like Rampardos. When they were first seen, they were both overhyped, but when people started to use them they realized the guys just as weren't as good as they looked. Cube (Kyu-B) can still be very effective at what it does, but it's not a metagame defining force like rain or Genesect.
