I might as well post what I have posted in the NU forum for other people to look at. It includes the top 10 NU leads.
The Top Ten Leads
By looking at the July usage statistics, below will be the current top 10 leads used on the ladder in the NU metagame.
Lead #10 - Cloyster
Cloyster has been seen a relatively unusual lead. With its huge Defense stat, it definitely makes it worth using as most of the top 10 leads are physically based. Not only that, but Cloyster has access to Ice Shard and Explosion which can really throw some people off guard. Also, it has access to Spikes and Toxic Spikes which it can set up quite easily and can then finish its job by exploding in the opposing Pokemon's face.
Lead #9 - Floatzel
Thanks to Floatzel's amazing base Speed of 115 and having access to Taunt definitely makes Floatzel a reliable lead. Since it has access to Taunt and is coupled with its high Speed, Floatzel is capable of stopping opposing leads from setting up entry hazards, leads that are planning to boost their attacks via boosting moves, or leads that attempt to induce status. Floatzel is also capable of setting up on its own by setting up Rain Dance or by boosting its respectable base 105 Attack further by using Bulk Up and attempting to sweep by using its powerful STAB Waterfall.
Lead #8 - Venomoth
Venomoth may seem a bit worthless because of its pitiful defensive stats, but it does have a few things that help improve its leading capabilities. First off, it has access to the second most viable sleep move in the game, being Sleep Powder which has a 75% chance to cause the opponent to fall asleep. Not only that, but it can boost Sleep Powder's accuracy up to 82.25% by wielding Wide Lens. Having a base Special Attack stat of 90 is definitely not to be underlooked, as it has two very strong STAB moves which are Bug Buzz and Sludge Bomb. Even though it may not have such great type coverage, its ability Tinted Lens allows it to hit Pokemon that resist its STAB attacks for double the damage. Lastly, Venomoth is another viable lead to set up Toxic Spikes early in the game because of its decent Speed stat and having Sleep Powder.
Lead #7 - Entei
Entei sadly doesn't have such a great movepool, but as a lead, Entei has definitely found a way to forget about its terrible movepool and attempt to wreak havoc with Eruption. With a great base Speed stat of 100 and a decent base Special Attack stat of 90, Entei can become a viable Choice Scarf or Choice Specs lead by attempting to destroy the opposing team by repeatedly using the all powerful STAB Eruption with a mighty base power of 150 assuming Entei is at full health.
Lead #6 - Jumpluff
Jumpluff is probably known as one of the most annoying Pokemon to fight. The reason for this is because of its high base Speed stat of 110, which allows it to reach a maximum of 350 Speed. Not only that, but it also has access to Sleep Powder, being able to outspeed most of the common leads and sleep them before they have a chance to move. Jumpluff also has the popular Leech Seed and Substitute combo, and with its great Speed, it can definitely abuse this and frustrate the opponent. But that's not all, Jumplufff unsurprisingly has access to Encore, another move that can really annoy the opponent as it can easily Encore as the opponent attempts to attack after setting up an entry hazard and can easily end a Pokemon's chance at boosting its stats, which will definitely force multiple switches.
Lead #5 - Relicanth
Relicanth may seem underlooked, but being in the 5th position lets everyone know that Relicanth is still viable. Having a huge base 130 Defense stat coupled with its high base 100 HP stat definitely makes Relicanth a tough lead to take down since most of the common leads are physically based. It can also reliably set up Stealth Rock due to its grand defenses. Even though it has a big Defense stat, its base 90 Attack stat should never be looked down upon. With its ability Rock Head, it can safely use Head Smash and dent practically anything that doesn't resist it. Not only that, but most of the Pokemon that resist Rock-type attacks are hit for super effective damage with Waterfall.
Lead #4 - Purugly
Purugly plays the same role as Persian, as it is quite identical. Having a reliable Speed stat and having Taunt, Fake Out, Hypnosis, and U-turn definitely makes it worth considering. It also has the ability Thick Fat which makes it slightly more bulkier then Persian, but it still lacks the defensive stats to use it effectively. The only advantage Purugly has over Persian is that its Attack stat is higher, making Return much more stronger. On the other hand, its Fake Out attack does less damage since Persian receives a Technician boost. Even though Fake Out won't do as much as Persian's would, Purugly does have one move that Persian fails to get; Sucker Punch. Purugly is the only Pokemon that can use the Fake Out + Taunt + Sucker Punch combo in NU (aside from Croagunk), and this makes Purugly stand out much more then Persian when it comes to leading.
Lead #3 - Gligar
Gligar is definitely successful as a lead. It basically has everything a lead needs. Decent Speed, respectable Attack, great overall bulk, many support moves, and having a great dual typing makes it a primary choice when it comes to leading. Gligar also has the power to fit practically any lead role. It can become defensively bulky, it can become fast and powerful, it can Toxic stall with Roost, and it can use Taunt to stop the lead from setting up Stealth Rock, which it can then set up its own.
Lead #2 - Persian
Persian is in second place for a good reason. Having a great Speed stat that reaches a maximum of 361 and moves such as Fake Out, Taunt, and Hypnosis definitely make it worth considering. Fake Out allows it to break the opposing leads Focus Sash and can stop them from setting up with Taunt, or can easily use Hypnosis to put the lead to sleep. Not only that, but it's ability Technician makes Fake Out much more stronger then usual and it can definitely hurt defensively frail Pokemon. It also has U-turn which it can use to its advantage. If you successfully sleep the lead, the opponent will most likely switch out, allowing you to U-turn on the switch-in and you can then choose the most appropriate Pokemon to handle it.
Lead #1 - Pinsir
And finally, the biggest of all leads. Being in first place, Pinsir makes a fantastic offensive lead. Having a huge base Attack stat of 125 coupled with its decent base 85 Speed stat definitely makes Pinsir one of the most threatening leads. X-Scissor is its strongest offensive attack as it receives a STAB boost and severely dents many leads. Even though Pinsir is used offensively as a lead, it definitely makes a reliable Stealth Rock user as it can set it up as the opposing lead switches out from being hit by one of Pinsir's powerful moves in the fear of being KOed.
That's all. Tell me if I missed anything. :S
