Magmar

With Magmar's naturally reasonable bulk and high Speed and attacking power, it makes one of the best mixed sweepers in OU NFE. Fire Blast is Magmar's main STAB attack, and KOs nearly any Metang, Piloswine and some forms of Bronzor with no trouble. Hidden Power Ice ensures that Gligar is dealt with easily, and covers Dragonair and Shelgon for more damage than its other attacks. However, without Hidden Power Grass, Magmar will be countered by both Marshtomp and Rhydon, and as such, one should consider their team when making the decision on which Hidden Power to use. Psychic seems like an odd choice, but is Magmar's best answer to both Monferno and Machoke, the latter whom can do serious damage with Dynamicpunch. Thunderpunch covers Water-types to an extent, although Magmar will still have issues with bulkier Water-types such as Poliwhirl.

200 Sp Atk allows Magmar to always OHKO the standard Bronzor with Fire Blast, while muscling a 92% chance to do so with no SR at all. If said Bronzor has Heatproof, however, Magmar has only a 64% chance of 2HKOing, which is still useful in itself. It also guarantees a OHKO against the standard Piloswine, even with no Stealth Rock support, and also KOs the standard Screen-setting Metang. 200 Sp Atk also 2HKOs the standard Dragonair and Bulky DD Shelgon, while the remaining Attack EVs also score a 2HKO against the standard Seadra and Croconaw, although it should be noted that Magmar's Fire Blast does more damage to Golbat and Murkrow than either Hidden Power Ice or Thunderpunch thanks to STAB.

Magmar's blazing Speed and ability to scare off a lot of OUs from fake threats of the MixMar set make it a perfect candidate for a surprise Belly Drum and Substitute combo. Even with no Attack investment, Magmar gets enough Attack to OHKO nearly the entire OU NFE tier. Even Rhydon cannot weather a +6 Brick Break. Nosepass also falls to Brick Break, as does Poliwhirl after Stealth Rock damage. Marshtomp and Shelgon are 2HKOed by Magmar, so prior damage to them is needed for a KO. Disposing or weakening of Magmar's typical counters before using this set is key to its success, as Magmar's Belly Drum and Substitute combo is a one-shot pony because of lack of recovery. If Shelgon or Marshtomp switch in while Magmar finally finished setting up, its biggest asset would be a 2HKO on either of them, ruining a sweep. Electabuzz is also a considerable foe when using this set, as it also isn't OHKOed.

After Belly Drum and Substitute, Magmar will have no need for defensive investment, and its Substitutes are broken by almost any attack aimed at it in NFE, making Speed and Attack power Magmar's main selling points. It's important to have an odd-numbered HP stat with this set because without it, Magmar cannot use Belly Drum and Substitute together, ruining its strategy. One would have to use Belly Drum immediately if an even-numbered stat is used, making Magmar extremely susceptible to priority attacks that will end it. Even Sneasel's Ice Shard will end up finishing it in spite of being resisted.

While this set may have the same moves as MixMar, it plays very differently. Scarf Magmar serves as a nasty surprise for Haunter, Diglett and Electabuzz who expect to outspeed and damage/KO Magmar.

The Speed EVs allow Magmar to outpace the standard Scarf Gabite by one point thanks to Choice Scarf, and allows Magmar to outspeed Sneasel. 200 Attack is invested to ensure a 2HKO against a standard 252 Atk / 252 Spd Seadra and Croconaw with Thunderpunch, even with no Stealth Rock in play. The remaining EVs are delegated to Special Attack to aid in Hidden Power and Fire Blast damage, although it should be noted that the majority of Marshtomps will always be 2HKOed by this set. If you fear Marshtomp more than Croconaw and Seadra, one option is to switch to a Mild Nature and go with 252 Sp Atk, which will OHKO any Marshomp who doesn't carry a Careful Nature, or with an alternative Nature, one who doesn't invest very heavily in Special Defense.
