I'm not disagreeing, but saying is quite a simplification. A team with a Compound Eyes Specs Syclant is also going to need to protect the Syclant from the 4x SR weak. Every time Syclant makes a kill it can easily be forced out by a faster Poke, or something it can't 1HKO. That gives a SRer chanece to set up, or a Poke to block Rapid Spin a chance to come in So it is quite like Garchomp, or Tyranitar. There's no "Switch this Pokemon in and you'll be fine" counter, but after you determin what kind of set it's running (which can be determined in part by the type of team working around it. Abomasnow present? It's Mountaineer. Two spinners? Compound Eyes.) After that it's about exploiting the weakness of that type and wearing it down (knock off will be a big help). I think that if this Poke was introduced into the standard Metagame you would either tack it onto a team and find that it's not so big a help as you thought it was, or you build a team around it's ability to take out walls, and it could be quite sucessful.
