I've tested this set, and when I actually got to use it (i.e. when the rest of my team didn't win first), it was able to sweep more often than not. I have saved some of the logs. They are not any particular ones, just random ones were Magnezone was used. I know that at least a few of them show sweeps.

<p>Unlike other Magnezone sets, this one focuses on setting up for a sweep, rather than revenge killing. Magnezone can use Charge Beam, Magnet Pull, and good defenses to set up, while still providing its team with key resistances. Charge Beam is the driving force of this set, as it enables Magnezone to raise its already mighty Special Attack. Substitute offers this set several things. Most importantly, it allows Magnezone to activate Salac Berry and raise its poor Speed to acceptable levels. It also gives Magnezone a shield against opponents that outspeed it. Finally, it protects Magnezone from debilitating status effects, especially paralysis. Thunderbolt and Hidden Power Ice offer Magnezone the greatest possible type coverage, being resisted in OU only by opposing Magnezone. Hidden Power Grass is also an option to hit Swampert or Mamoswine, but several other Pokemon will now wall you, such as Celebi and Latias. Flash Cannon gets STAB and can easily OHKO Tyranitar, Rhyperior, and Mamoswine after a boost, but it can't touch Swampert.</p>
<p>Magnezone hits 331 Speed after a Salac boost with 180 Speed EVs and a Timid nature, outspeeding +Speed base 100 Pokemon and the common MixApe. Special Attack is maxed so that Magnezone will hit as hard as possible. The remaining EVs are allocated to HP, creating sturdier Substitutes, with Salac Berry activating after three uses. Being resistant to Extremespeed, Bullet Punch, and Ice Shard, Magnezone does not have to fear priority attacks aside from the rare Mach Punch or Vacuum Wave. Using 228 HP/100 Def/84 SAtk/96 SDef as the EV spread along with Leftovers, Magnezone can more easily set up on stall teams. With this spread, it can survive 4 Seismic Tosses from Blissey at full HP, and take three Bullet Punches from Scizor per Substitute while still having the necessary power to deal with other Pokemon, especially after several boosts. If outrunning max Speed Adamant Scizor is a priority, then 36 EVs should be shifted to Speed from HP.</p>
<p>While many Pokemon are able to effectively use a SubSalac set, Magnet Pull gives Magnezone a distinct advantage. With Magnet Pull, Magnezone can easily set up on Steel-types such as Scizor or Jirachi locked into a resisted attack. Magnezone also is immune to sand damage, unlike Jolteon and Rotom. Once Magnezone has accumulated enough boosts, it can easily kill the helpless Pokemon and proceed to sweep. Because of the popularity of Steel-type Pokemon, Magnezone should have no trouble finding a way to set up.</p>
<p>The easiest way to beat this Magnezone is by either using a Pokemon that is faster than it or one that will survive an attack. In OU, Magnezone has the most trouble with Swampert, Rotom, Azelf, Gengar, Latias, Starmie, and Blissey. A specially defensive Tyranitar or Scizor can easily take out the four faster Psychic- and Ghost-types with Pursuit and severely damage Blissey. Swampert is handled by any Pokemon with a Grass-type attack, such as Infernape or Celebi, and is incapacitated by Toxic or Toxic Spikes. Blissey can be beaten by most physically-oriented sweepers, particularly those with a Fighting-type move. Dugtrio also deserves a mention due to its ability to trap and kill Blissey and beat Azelf and Gengar through either Sucker Punch or Pursuit. Paralysis will help enable a sweep by crippling any opposing Choice Scarfers. Finally, "Pursuit-bait" Pokemon such as Rotom and Latias and "Bullet Punch-bait" Pokemon like Gengar and Tyranitar are excellent additions to your team since they will easily lure out Scizor and Jirachi. This will allow Magnezone to come in after a kill and set up on a resisted attack.</p>
<p>Tricking a Choice item onto virtually any Steel-type Pokemon is the best way to facilitate a Magnezone sweep. The best candidates for this role are Rotom, Gengar, and Latias. All three resist or are immune to Fighting- and Ground-type attacks, Magnezone's two most common weaknesses, while Latias has the added benefit of resisting Fire-type attacks. This means an opposing Pokemon will almost never select an attack that is effective against Magnezone. Magnezone can then switch in on the most likely resisted attack and set up Substitutes and Charge Beams.</p>
