Name: The Great Wall
move 1: Stealth Rock
move 2: Gyro Ball
move 3: Earthquake
move 4: Light Screen / Reflect
Item: Oran Berry
EVs: 220 HP / 4 Atk / 148 Def / 68 SpD
IVs: 0 Spe
Bronzor's biggest problem is Little Cup's Level 5 restriction removing its ability to carry Hypnosis, which it learns at Level 7. As such, its movepool is limited to only the TMs it can learn. Stealth Rock is the main attraction -- Bronzor will always get that Stealth Rock off. Gyro Ball and Earthquake are Bronzor's best attacking options -- Earthquake hits the incoming Fires Super Effective, while Gyro Ball has STAB and great Base Power. Recycle would be a great option, but unfortunately, it's not currently available in Shoddy Battle. Last, but certainly not least, you can throw up a barrier to help your other Pokemon.SET 2
move 1: Trick Room / Rain Dance / Sunny Day
move 2: Stealth Rock
move 3: Gyro Ball
move 4: Earthquake
Item: Oran Berry / Damp Rock / Heat Rock
EVs: 220 HP / 244 Attack
IVs: 0 Spe
Throw down Rocks, set up weather or Trick Room, hit some stuff as hard as you can until you drop and let your next star take the field. The EVs give Bronzor a reasonable 13 Attack. The Trick Room set gets priority here, as Bronzor's lack of alacrity is contested only by Trapinch and Munchlax. The item should correspond with the set, Damp Rock and Heat Rock for Rain and Sun teams respectively.SET 3
move 1: Calm Mind
move 2: Rest
move 3: Sleep Talk
move 4: Psychic / Flash Cannon
Item: Oran Berry
Nature: Modest / Bold
EVs: 220 HP / 148 Def / 84 SpA
Gimmicky, but it might work. Bronzor's attacking stats are awful, but with a set like this, even Bronzor's meager 11 Special Attack (with Modest) can reach fearsome heights, while becoming an impenetrable bulwark against Special attacks. Works like Crocune -- stat up for a while, then Rest and begin to Sleep Talk for boosts or massive damage. Psychic is the strongest STAB that Bronzor carries, but its inability to hit Dark-type pokemon combined with the fact that Murkrow and Houndour are ever-present makes Flash Cannon a viable attack. The nature is your choice -- Bold lets it take physical hits more effectively, while Modest boosts its power slightly.OTHER OPTIONS
Bronzor's options are rather limited by Move Legality. Rain Dance can also be used in the place of Reflect or Light Screen on the first set to remove Bronzor's only weakness for a Spiritomb-esque feel. If/When Recycle is implemented, it can act as steady healing for a Bronzor with an Oran Berry.ILLEGAL MOVES
Hypnosis is the biggest legality issue, but there are also a couple of moves that get lost due to lack of gender. Confuse Ray is also illegal. Moves of lesser note are Iron Defense, Imprison, Extrasensory, Faint Attack, and Heal Block.EVs
The preferred EV spread depends on the set. The main spreads advocated in this analysis give a balanced defensive spread that splits the EVs and nature to ensure that it can take hits on both sides of the spectrum. If one wishes to do so, however, Bronzor can be EV'd for a more defined defensive ability. 220 HP maxes its HP, whereas, 228 Def/SpD will max the requisite defense. From there, the remaining points can be dropped into Attack, giving a Bronzor that is equipped to handle one type of damage very well and hit with more power than the standard Bronzor, though it sacrifices defense on the other side.
The Setup form of Bronzor isn't meant to wall, so it can use HP for relative sturdiness and then pour the rest into offensive power. The CroZor set's EVs give it reasonable defense, while giving it 10 SpA (with Bold) for the most benefit from Calm Mind.OPINION
Bronzor is pretty harmless, but in terms of providing aid to a team, it's second to none. Laying Stealth Rock, using Reflect and Light Screen, it can let other members of your team set up easily. If you need defense on a Little Cup team, Bronzor should definitely get a look.COUNTERS
The most common set for Bronzor has a number of notable counters. Ponyta will come in on a Gyro Ball and resist it (watch out for Earthquake), and OHKO with Flare Blitz. Cyndaquil is similar with Eruption. Krabby can come in and resist the Gyro Ball while shrugging off the Earthquake with its excellent defense and pound it with neutral Crabhammers. Really, anything that has decent Defense and a Fire attack can scare Bronzor off, and it's really not that hard to outspeed either.
Setup sets are slightly harder to counter. If Bronzor is packing Trick Room, Fire-Types such as Ponyta come in and then have to run from the incoming EQ. The only things slower than Bronzor are Munchlax and Trapinch, and none are equipped to handle Bronzor. However, bulky Water-types such as Krabby remain able to trade hits expertly with Bronzor. Rain Dance sets trade a weakness to Fire for taking more damage from Water attacks, and as such, Pokemon such as Krabby become a much more viable counter. Sunny Day sets are rather suicidal, as the Sunny Day increases the power of the moves that hit its only weakness, but at the same time, Water-types lose much of their potency against Bronzor.
CroZor gets beaten in much the same fashion, but with one major difference -- unboosted Special Attacks are nearly useless against a Calm Mind-empowered Bronzor. Ponyta is the biggest threat -- Flare Blitz will OHKO, and it can come in for free on a Calm Mind or a Rest for the kill. Taunters can ruin it as well, removing its ability to stat up and heal, making it a slow, mediocre special attacker. Finally, the last set of counters depends on the set. Sets with Psychic get ruined by Dark-types such as Murkrow and Houndoom, while the Flash Cannon set gets completely shut down by Mantyke and Chinchou, the latter especially due to a 4x Steel resistance.
As for Revenge Killing, it's easy to come in and finish off a wounded Bronzor if it manages to down one of your Pokes. Most anything with a fire attack can come in and make short work of Bronzor, while avoiding the danger of switching into a powerful Gyro Ball or Earthquake. Of these revenge killers, Cranidos stands out for being able to hit it with Earthquake due to its Mold Breaker ability.
Bronzor demonstrates an extreme inability to threaten Gligar, so it can come in on whatever Bronzor would throw at it and proceed to get free Swords Dances, though one must bear in mind that after a Rock Polish/Agility, the formerly weak Gyro Ball becomes an easy 2HKO against all but the most defensive sets.
