I think this set is in many ways inferior to Rotom's SubCharge set. If Zone is not using Salac Berry, that hurts his ability to sweep due to bad speed. If he is using Salac Berry, then that limits the number of chances magnezone gets to set up. Rotom does not have this issue due to his adequate speed, and subsequently, his ability to run leftovers on his subcharge set. Rotom's set also has a much easier time against stall, being able to set up in the face of all forms of Blissey except for cm (zone cant set up on flamethrower or seismic toss sets) and easily KO-ing every other member after just a couple of boosts. Zone does not have as many places to set up; the only steel-types zone sets up on are bronzong, non shed-shell skarmory, and non shed shell forretress. Forretress was seen on 6.4% of teams, 20.9% of Forretress used Shed Shell as their item, and 15.9% of them had Earthquake. Bronzong was on 7.7% of teams, and 49% carried Earthquake and a large investment in special defense. 39.1% of Skarmory, who appeared on 7.8% of teams, had shed shell. It just seems like a very situational strategy to me.
This set is not meant to set up on Blissey, it's meant to set up on Jirachi and Choiced Scizor. It should not set up on things like Forretress and Bronzong who can kill it with earthquake. I agree that it is somewhat situational, but these situations will often pay off in spades. Being able to set up on a locked and trapped 2x or 4x resisted attack will pay off in the long run, especially with Jirachi and Scizor being so common. Quite honestly, I've been seeing way more Jirachis and Scizor than I do Blissey.
