A few people I've talked to, including myself, found the current Bronzong Analysis to be somewhat lacking... So I decided to rewrite it to improve the quality. Note that the Trick Room set and Counters section were left as is because they seemed fine the way they are. The Rain Dance set comes courtesy of Aldaron, since it was very nicely done, there was no need to make another ;o The Screener set also comes courtesy of RaikouLover.

<p>Bronzong is an excellent Pokemon to set up Stealth Rock as well as wall many offensive Pokemon on both the physical and special side of the spectrum. With its above par defenses and many resistances, Bronzong can set up rocks and / or sleep something with relative ease. Being one of the slowest Pokemon in the metagame, Bronzong can use its STAB Gyro Ball to OHKO fast sweepers like Weavile and Scarf Gengar, and 2HKO other sweepers, including Tyranitar. Earthquake allows Bronzong to hit Pokemon that resist Gyro Ball, mainly Infernape and Heatran, (the latter of which is not OHKO'd) who would otherwise destroy Bronzong with their STAB Fire attacks.</p>
<p>Bronzong makes an outstanding setter up of Stealth Rock, however, if you prefer to use something else, you can forgoe Stealth Rock for the powerful finishing move, Explosion. Said finishing move can do massive damage to standard Blissey and severly cripple or KO other common Pokemon. Alternatively, Reflect or Light Screen can be used if you feel your team could use the support. Lum Berry is a viable option if you're using Bronzong as a lead, as it can counter the many "sleep leads." Charge Beam is a fine choice for the last slot too, as it hits Gyarados and Yanmega, among other Pokemon. Hidden Power Ice can also be used in the last spot to hit Salamence and Dragonite, though some Special Attack investment is needed to 2HKO them.</p>
<p>The EVs listed may look a bit strange, however, they fully maximize Bronzong's potential. The HP is maximized because not only does it help Bronzong's below average base HP get a boost, but it allows Bronzong to take four Seismic Tosses (with Leftovers recovery). The Attack EVs allow Bronzong to OHKO Scarfed Gengar and Weavile, and 2HKO Tyranitar, with Gyro Ball. They also allow the bell to OHKO Infernape and Heatran with Earthquake. The Special Defense and Defense EVs maximize Bronzong's defenses, allowing it to not be OHKO'd by MixApe's Flamethrower or +Speed Nature Heatran's Fire Blast. It also survives a SpecsMence's Fire Blast.</p>

<p> Bronzong is arguably one of the best transition pokemon in the game, able to come in on his multitude of resists and force many pokemon to switch out. This set is designed specifically to benefit the team by using every switch in to set up an 8 turn screen for the team. As far as attacks go, Gyro Ball will allow Bronzong to easily defeat fast opponents such as Gengar, Yanmega, and Deoxys... all of whom will struggle to do damage with the appropriate screen in place. Earthquake is always a favorable option on Bronzong for nailing Heatran, Infernape, and Magnezone switch-ins. Explosion rounds out the set by allowing a teammate a free switch in after a screen is in place. </p>

<p>The standard Bronzong is capable of setting up a variety of supporting moves and doing decent damage on many Pokemon with its attacking moves and good Attack stat. Usually, a supporting Bronzong is used as a leading Pokémon, as its excellent set of resistances and immunities mean it can easily set up a layer of Stealth Rock or sleep an opponent with Hypnosis before anything else. Gyro Ball is the reason this Bronzong is recommended to be as slow as possible; at a meager 63 Speed, Gyro Ball strikes at near-maximum power on common opposing leads such as Weavile or Gengar. Not too much is capable of withstanding a couple of STAB boosted attacks with over 120 base power, even if Bronzong's Attack stat may leave a bit to be desired. Unless you fear Magnezone to a great extent Explosion will prove the most useful attacking choice in the final slot. That way, you'll be able to hopefully cause a KO on the opponent then proceed to sweep under Trick Room.</p>

<p>While Bronzong makes a fantastic wall with its ample resistances and many support moves, it does however lack a recovery move. This set remedies that problem. Rest and Sleep Talk allow Bronzong to become the status absorber of the team while retaining its walling abilities. Rest and Sleep Talk are, obviously, the core moves of this set, allowing Bronzong to recover any damage and detrimental status it may have acquired. With its abysmal Speed, Gyro Ball can often function at maximum base power against sweepers like ScarfGar and Deoxys-S. Earthquake gives Bronzong good type coverage with its STAB move, letting it hit Pokemon that resist Gyro Ball, namely Heatran, who is OHKO'd by Earthquake. It should be noted that this set isn't perfect. Bronzong cannot inflict much damage to many of the common sleep inducers. These include Breloom, Yanmega, Milotic, Tangrowth, and other Bronzong.</p>
<p>The EVs are almost identical to the first moveset, however, with the lack of Hidden Power Ice Special Attack EVs are no longer necessary. However, if you feel like this Bronzong should be your counter to the OU Dragons, use Hidden Power Ice over Earthquake. However, you will need 24 EVs (which you can take from Defense) and add them to Special Attack to guarantee a 2HKO on Garchomp, Salamence, and Dragonite (though Dragonite is only 2HKO'd with Stealth Rock damage). Sassy is the preferred nature for this moveset because while Relaxed is also beneficial to Bronzong by lowering the amount of damage Zong takes from physical attacks, Sassy is much more helpful. For example, while Relaxed lowers the amount of damage taken from Breloom's Focus Punch, it is still a 2HKO, just as it is when using Sassy nature. Also, when using Sassy, Bronzong is able to survive SpecsMence's Fire Blast, where Relaxed is unable to do so.</p>
[SET]
name: Torrential Zong
move 1: Rain Dance
move 2: Explosion
move 3: Stealth Rock
move 4: Hypnosis
ability: Levitate
nature: Impish
item: Damp Rock
evs: 252 HP / 128 Atk / 128 Def
[SET COMMENTS]
<p>Very rarely is a Pokemon perfectly suited to provide almost exactly what a particular style of team requires. Then again, not many Pokemon have the utility capacity that Bronzong possesses. The EVs are set to give Bronzong more physical bulkiness, as Rain Dance will allow it to survive most Fire Blasts and Flamethrowers, the common special attacks thrown at it. 128 Attack is given to give a boost to Explosion, allowing it to always OHKO 252 HP / 0 Def Snorlax, a common deterrent to Rain Dance teams.</p>
<p>Rain Dance teams require a few factors to be ultimately successful: long lengths of Rain Dance, Stealth Rock, and the removal of some arbitrary Pokemon so that proper switches can be more effectively handled. Bronzong sets up Rain Dance for 8 turns with Damp Rock, allows efficient switching in by Exploding (possibly on a counter), removes a threat by using Hypnosis, and sets up Stealth Rock, so Kingdra can get that guaranteed OHKO on Metagross and Kabutops can get that guaranteed OHKO on other Bronzong.</p>
<p>The reason Gyro Ball and Hidden Power Ice are ignored here is that this Bronzong isn't supposed to be an attacker or last a long time, so these moves are unnecessary. The sole purpose of this Bronzong is to come in sometime in the early to middle parts of battle (note it is not an effective lead), set up Stealth Rock, use Rain Dance, possibly Hypnotize the opponent and then Explode away, leaving 6 turns of Rain for sweepers such as Kingdra, Kabutops, Omastar, or Relicanth.</p>
[OTHER OPTIONS]
<p>A Calm Mind set is somewhat viable. However, you'll usually be Blocking your opponents counter to Bronzong, including Heatran, Infernape, and SpecsMence, none of whom you'll be able to Calm Mind against. However, Bronzong does have a good special move pool, including Charge Beam, Psychic and Grass Knot. The latter of which can be used for massive damage against Rhyperior, Hippowdon, and Swampert. However, due to the Special Defense boost in Sandstorm, Gyro Ball is a better option against Tyranitar. With its many resistances and above-par defenses, Bronzong can effectively use Toxic to stall down opponents, though a lack of recovery hurts. Shed Shell is another possible item choice so you can escape the binding effects of Magnet Pull.</p>
<p>Heatproof is a decent ability to fool an opponent, though you wouldn't be able to switch into Earthquake, and any Fire-type attack will tip off an opponent that you are using Heatproof. Also, switching into Spikes will give away your ability because you would not take damage while using Levitate. Leftovers is usually the preferred item, however, Lum Berry is viable so Bronzong can take a Hypnosis from fast sleep inducers, recover from sleep, and hit back with its own Hypnosis. Also, Macho Brace is a viable choice because it will drastically increase the power of Gyro Ball, hitting even Blissey for a good amount of damage.</p>
[EVS]
<p>Picking out EVs for Bronzong is tricky because it has many different walling and support options. However, for every set you need to maximize HP. While max Leftovers recovery is only eight EVs down from max, when using max HP and Leftovers, you can survive four Seismic Tosses, instead of three. This is crucial when you want Bronzong to set up on Blissey or another Seismic Toss user. After maximizing HP, you'll want to use just enough EVs in the other stats to prove most beneficial. Ususally this involves little attacking EVs while pumping the defenses.</p>
<p>You'll want Bronzong's Speed to be as low as possible to increase the power of Gyro Ball, thus a -Speed nature along with a zero Speed IV.</p>
[OPINION]
<p>With its many common resistances, and only one weakness, Bronzong can make a fantastic Support Pokemon. Its resistances to Rock, Dragon, Ice, and Ground make it a good counter against Pokemon like Weavile, Tyranitar, and Garchomp, as it resists their STAB moves. Though Bronzong can take attacks like Salamence's Draco Meteor, it cannot take repeated powerful attacks due to lack of recovery. Because of this, it is recommended to have a Pokemon with Wish to help Bronzong recover HP.</p>
[COUNTERS]
<p>Thanks to Magnet Pull, Bronzong fears Magnezone if it doesn’t have Earthquake to stop it, and even that can be foiled by Magnet Rise.</p>
<p>Gyarados Intimidates and resists Gyro Ball, but can be Hypnotized or hit by Charge Beam. In fact, most bulky Waters can switch in on Bronzong and slowly wear it down with Surf. Suicune is especially dangerous because it can get a Calm Mind sweep going if Bronzong is foolish enough to stay in. If Bronzong has Rest, it can outstall some Water-types however. Infernape can also switch in on a Gyro Ball and survive, and can finish off a weakened Bronzong—however, if it switches in on Earthquake, its dead. Heatran is in a similar boat, except it takes practically nothing from Gyro Ball thanks to lower Speed, good defenses, and a 4x resistance to Steel. It needs to be able to OHKO Bronzong or it will just get slapped by an Earthquake, assuming Bronzong stays in. Moltres can come in on Bronzong pretty much regardless of what it uses, with the exception of Hypnosis and Explosion. Pressure will eat up two of Gyro Ball's precious 8 PP, and Moltres has STAB Flamethrower to hit back. Moltres also often carries Substitute to block any attempts at Hypnosis once it gets in. Charizard can use Bronzong as a way to set up a Belly Drum sweep, because it usually lacks anything to really damage Charizard with, aside from Explosion (and Charizard often packs Substitute).</p>
<p>Flamethrower Blissey wears it down, assuming Bronzong doesn't have Explosion. Calm Mind Blissey is much of the same, except that it can actually set up something. Celebi can use Leech Seed and easily PP stall, as even Explosion won't OHKO Celebi. Even if Celebi doesn't have Leech Seed, most sets will have more PP than Bronzong does, so they will win a PP war if it comes down to that. Celebi could also Calm Mind up and either overpower Bronzong or Baton Pass out of there. Skarmory can come in on anything Bronzong does and set up Spikes. It doesn't even have to worry about the Block set because Skarmory can use Whirlwind to remove any set up.</p>
---------------------
I left the Trick Room Set, as well as the Counters section, the same as the original analysis, because I felt like there wasn't anything more to say, and tweaking them might actually be detrimental.
This analysis seems a little more in-depth, and it makes better use of Bronzong's EVs and abilities. Some of the not-so-good sets were removed too... Thanks to the people who helped proofread before I posted this, and help with EVs :D
