I'm going to give this a go; let's hope I don't get mauled by criticism. Gliscor @ Leftovers Team support Impish Nature (+Def, -SpA) 252 HP/252 Def/4 Atk - Stealth Rock - Earthquake - Knock Off - Roost While at first glance this just looks like a variant of the stallbreaker, it is actually a brilliant team player that is an excellent option if you're struggling with powerful physical attackers such as Dragonite or Metagross. This Gliscor isn't suitable as a lead, but is better to come in after a suicide lead has fainted, or after a bulky lead is switched out. The first thing you'll probably notice is the defensive EV spread; while this isn't common to see on a Gliscor, it takes hits marvellously on the physical side, which allows it to perform its role as a support Pokemon more efficiently. Using this EV spread, Gliscor can't be OHKOd by anything from a +2 Swords Dance Lucario, bar Ice Punch (which will fail to OHKO without the Swords Dance boost) The moves are fairly standard for a support Pokemon. Stealth Rock is a great move to use in conjuction with Spikes or Toxic Spikes leads, who are unable to set up their own Stealth Rock. If you're already using an SR lead, however, Toxic and Taunt are both good replacements, although remember that Gliscor won't pull off Taunt as quickly without the Speed EVs. Earthquake is Gliscor's obligatory STAB move that allows him to whittle down his opponent quickly. Knock off is probably the most interesting move here. Most Pokemon have some degree of dependency on their item, so no matter what the opponent switches to, they will end up with a Pokemon that can't perform as well due to losing their item. A Pokemon without its Choice item becomes significantly reduced in power, notable examples being Scizor and Flygon. Blissey without Leftovers becomes significantly easy to weaken, just make sure you know Blissey's attacks first, because you don't want to get knocked out by Ice Beam. Using Knock Off on Life Orb Pokemon reduces their effectiveness a fair bit, but also prevents the 10% health loss every turn, adding to their survivability. Finally, Roost allows you to stall out weaker attackers and keep Gliscor alive for as long as possible, not to mention shedding its Flying-type temporarily, which could allow it to take weaker Ice-type attacks if the need arises. Magnezone makes a great team mate to this Gliscor, as he can knock off a Shed Shell from Forretress or Skarmory, allowing Magnezone to reliably KO them, although it's best to keep Magnezone hidden until you do so, or else your opponent will instinctively switch out their Steel-type. Gliscor can also switch into Earthquakes aimed at Magnezone, while Magnezone can take most Ice attacks.
