DDR Master's post on the Creative Moveset thread gives me hope that Analytic Magnezone is not all talk, but actually viable in practice. As DDR Master shows here, Magnezone can run some Speed to check important threats, while still make use of switches and faster mons to abuse the Analytic boost.
My only question is whether or not Specs is the only viable option Analytic Magnezone have. Leftovers or Life Orb Magnezone with Metal Sound, Charge Beam and / or Substitute sounds appealing to me. Metal Sound allows Magnezone to even overcome Chansey / Blissey. Even more, Metal Sound would encourage switches, which would activate Analytic. Substitute with either LO or Charge Beam would protect Magnezone from faster threats, and retaliate hard with an Analytic-reinforced hit :d
