I've had a bit of experience with Fur Coat. It was pretty good, low on the ladder, because people would inexplicably stay in with Landorus, etc, netting you an easy kill with Surf. But Furfrou's shitty movepool really makes you a one trick pony, an unstoppable physical wall that's only good at Toxic stalling and not much else. If you had to give it to anyone, it would be Suicuine (which I've used to decent effect), but back when I first started I ran it on Slowking for some reason. Here's my one replay I have saved (which really shows off Unaware Umbreon more than anything). I had another match where I tanked +2 MPinsir Espeed and killed with Surf, and generally it makes any Pokemon a good GW, etc. check at the cost of their general usefulness. Of course, Mega Gyarados destroys you all the same.

I'm curious about this choice -- what does it give you? More accurate Bolt Strike + non-STAB V-create at the cost of Dragon STAB? I'd honestly rather stick with default Zek, or to go for Zard X, which gives Tough Claws + DD:Zekrom: Victini
