Lol, I'm just refering to the inevitable sequal/s as 'Z', and both these posts are off topic. I wish more things knew Rapid Spin. It seems like the kind of move more things ought to be able to learn. All you need to do is spin around really fast and have the extra appendage (Tail, trunk, various floppy bits like ears, in case of Hitmontop everything because he spins on his head, tounge?, MIND POWERS, etc) and that it really seems like an ideal candidate for the Tutor. Ultimatly, it's still a normal move (thus "spin blockers" would still be useful), but more pokemon would have access to it, allowing for better checks on specific spin blockers. Of course, there would be ONE mon w/ scrappy that they would give it to, and he would suddenly rocket into OU (Any of them, all of them, Pangoro w/ Spin and Parting remark for momentum!?).
Though this seems off topic, I just think with how powerful Stealth Rock IS (spikes and toxic spikes too... I guess. Oh, and Sticky Web), making it's answer more common would make it a less required strategy. As it stands, if you want to compete, you NEED a spinner/defogger on your team. With the full list of Defoggers from Gen 4 and forward, and another equally large list of Tutorable Spinners, I think it would free up the meta a bit. Hazards would still be crazy common, they're just too useful, but with a larger selection of answers, it would be a whole lot less easy to prepare for the counter strategy.
