It's a gimmick at best. Even with as much physical bulk and support options as possible, you're not getting the spin on Jellicent, and Gengar can check you unless it's Raining. The best Rapid Spinners in the tier are Forretress and Excadrill, since Forretress can Volt Switch out of Ghosts and into a Pokemon that can handle it, while Excadrill forces switches with its mere presence, and it's a safe bet Gengar or Jellicent won't try to block it.
