I was looking for a lead that wasn't called Metagross and I came upon this lead. It has the ability to beat most common leads and is an effective lead itself. It has problems with Swampert, Trick Jirachi, and Mamoswine leads. Apart from those it has been very solid and has been defeating the opposing lead a good amount of the time. The only other problem that Gliscor has is that it often loses any effectiveness after the Stealth Rock is down and the opponent's lead is KO'd, but by that time, the job is done.
The analysis is rather short, but the set isn't really that complicated to start with and it gets the job done.

<p>Gliscor has the movepool and stats to be an effective lead. It can usually set up Stealth Rock and often prevent the opponent from doing the same while being able to leave big dents in or possibly KO some of the common leads.</p>
<p>Stealth Rock is very useful as it discourages switching and weakens the opponent's team constantly. Taunt allows you to prevent slower leads from setting up Stealth Rock which can be vital to your team's success. Earthquake provides you with your strongest STAB move and can almost always 2HKO a standard Metagross. U-turn is useful if you are in a bad match-up, and it can severely damage Azelf, making it easy pickings for the likes of Scizor. Stone Edge is also an option as it is stronger and hits Aerodactyl significantly harder (even though it fails to OHKO) who completely shuts you down, but the accuracy is shaky and most leads are hit harder with Earthquake/U-turn than Earthquake/Stone Edge not to mention that U-turn also allows you to scout your opponent's switches.</p>
<p>The Speed EVs allow you to outspeed Adamant Lucario as well as Naive Heatran. This means that you always beat Lead Heatran and can be a reliable counter for Lucario later in the game. Meanwhile 88 Attack EVs guarantee that you 2HKO 252 / 0 Metagross as well as OHKO Lucario and Infernape. The rest of the EVs are tossed into HP to increase the overall bulk.</p>
