Spinning isn't really an issue either. The ghosts this gen all blow, and Ferrothorn with Rocky Helmet is about as close as you're going to get to an effective Spin Blocker. Maybe you didn't read that though.
I can't see why the opponent can't say, send in Forretress and set up hazards while you Spike up, then use Rapid Spin after you get a few layers up. It discourages spinning, for sure, but it doesn't stop it at all, and you only need to spin once to get rid of everything. I'd gladly trade 25% of Forretress' health to remove SR, 3 layers of Spikes and 2 layers of Toxic Spikes along with Leech Seed, I only need 4 turns of Leftovers to heal that back, while I just wasted 3-6 of your turns.
Whatevs sig. QC member for OU and Ubers, VM me for a look at your analysis. Just make sure it's good.
Also, if you want me to rate your team (OU/DW OU/Ubers), give me a VM. If I don't rate it, it's either 1) it's so shit it's too much trouble, 2) I'm busy, or 3) the team is fantastic and I have nothing I can suggest to you. You should be able to recognise which one.
