Bluewind, I was merely telling you what happened. I am aware that he could have switched into Charge Beam, and Blissey would fare just as well as other Magnezone. Still doesn't change the fact that Analytic Magnezone dishes out more damage than Magnet Pull Magnezone.
Afti, mention wilson46's HP Grass, but specify that this alternative is for the Specs set, since the Sub set would want the superior coverage of HP Ice.
Also AC Mention Metal Sound, which allows Magnezone to more quickly take down Blissey, Chansey, and Latias than Charge Beam. Even more, it also encourages switches, which would make the opponent vulnerable to Analytic-boosted hits.
