"The Rapid Spin set doesn't have a lot of counters per set, because anything that doesn't block Rapid Spin lets it do its primary job. Ghost-types like Rotom, Spiritomb, and Mismagius come to mind as counters, blocking Rapid Spin and being able to burn Hitmontop, or just attack Hitmontop with a strong STAB attack."
Found another typo, on hitmontops counters :)
