There's a Smogon thread on Sky Battles; they plan to try and implement it as an Other Metagame.
The available SR users are Aerodactyl, Skarmory, Lunatone, Solrock, Claydol, Gliscor, and the Landorus.
The available spinners are Delibird, Claydol, and Cryogonal.
The sole Magic Bouncer is Xatu.
There are only two spinblockers: Gengar and Drifblim. Neither of them want to take a strong attack from Claydol (who resists SR) because it can Psychic Gengar and Stone Edge Drifblim. I can see a Claydol set...
