I'm talking any tier, personal opinion, anything you feel defines a great spinblocker.
This is what Spinblockers essentially are. Them being immune to Rapid Spin thus blocking it, therefore the name. An ideal one would really be anything that's a ghost type. Most people use Sableye in OU and Cofagrigus for UU and under from my experience. Logically though, any ghost type would do.
Hope this helps!
