Do not be fooled by Garchomp's previous status as an OU Pokémon, because Garchomp is still a force to be reckoned with, even in the Uber tier. With a Choice Scarf, Garchomp is an excellent revenge killer that can stop sweeps from both Swords Dance and Dragon Dance Rayquaza. With a Choice Band, Garchomp is a fast physical powerhouse that requires no set up. Given that chance though, Garchomp can use Swords Dance to become a sweeper that can bring even Bold Lugia to its knees, single-handedly crumpling the Uber metagame with its mighty STAB Outrage. Give Garchomp the chance to sweep, and it will respond quickly with devastation, leaving only dust in its wake.
Choice Scarf Garchomp is an excellent revenge killer and cleaner in the Uber environment. Thanks to its base 102 Speed, Garchomp can easily outrun and revenge kill almost every other Dragon-type used in Ubers. Choice Scarf Garchomp is also one of the few things that can revenge kill both Dragon Dance and Swords Dance Rayquaza, thanks to its good defenses and higher Speed. Note that if Garchomp is a team's main method of dealing with Swords Dance Rayquaza, it is advisable to try keeping Garchomp at near full health until it has KOed it, as a Swords Danced, Life Orb Adamant Rayquaza deals 80%-94% to Garchomp with ExtremeSpeed and may KO it if it has previously taken any residual damage.
Outrage is important for this set, because Garchomp does not have the power of Choice Band to boost its attacks, Outrage's STAB and 120 Base Power help make up for the lack of a boost. STAB Earthquake is also important for coverage, taking out Steel-types such as Dialga, and Metagross. Dragon Claw is weaker than Outrage; however, it retains Garchomp's freedom to switch out of battle if the need be. Stone Edge is the best option for the final moveslot, as it is capable of OHKOing Ho-Oh and, with Stealth Rock damage, has a chance of 2HKOing Timid Lugia. A Fire-typed move can also be used in the last slot (either Fire Blast or Fire Fang) if you are bringing sun support, to do a severe amount of damage to Forretress and Scizor. Toxic can also be used in place of Stone Edge to cripple Lugia and Groudon.Team Options & Additional Comments >>>
Garchomp's main advantage over Rayquaza as a Swords Dance sweeper is its Speed. Seven base points may not seem like much, but outspeeding Hasty Palkia is invaluable. It also gives Garchomp a chance of decimating most Latias who don't invest heavily in Speed. The lack of ExtremeSpeed is rather unfortunate for Garchomp, but with its bulk, typing, and ability, it's still very viable. Immunity to Thunder also allows Garchomp to potentially switch into Choice Specs Kyogre and obtain a free Swords Dance while Kyogre switches out.
After a Swords Dance, and with the power boost of Life Orb, Garchomp is nearly unstoppable offensively; being able to outspeed a large portion of the Uber metagame and outright OHKO even Support Groudon, one of the most physically defensive Pokémon in the tier, after 3 layers of Spikes and Stealth Rock. This, added to a STAB Earthquake with which to wreck grounded Steel-types, such as Dialga and Metagross, that are able to take a boosted Outrage, and you'll realize that there are very few Pokémon left that can be relied on to defeat Garchomp.Team Options & Additional Comments >>>
Garchomp makes a fantastic user of Choice Band in the Uber environment. With 333 Speed and 538 Attack, not a whole lot can switch into this set safely. Opponents expecting the Choice Scarf variant will be surprised when Earthquake 2HKOes many of the set's common switch-ins, particularly Scizor and Wobbuffet. Earthquake will also OHKO most Dialga (unless it has used Bulk Up once) and any other grounded Steel-type in Ubers. Outrage is an excellent clean-up attack to use once the main threats to Garchomp have been eliminated, and can even 2HKO Support Groudon after Stealth Rock. Outrage should always be used with extreme caution though, because once it is used, Garchomp cannot switch out and is forced to use it repeatedly.
Stone Edge is Garchomp's best move against Lugia, and although Garchomp should not square off against Timid Lugia, Bold Lugia will be 2HKOed by Stone Edge after Stealth Rock. As with the Choice Scarf set, Dragon Claw is useful for finishing off weakened Pokémon without any of the issues of the other moves.Team Options & Additional Comments >>>
This set allows Garchomp to safely Swords Dance without as much prediction, thanks to Substitute. Behind the Substitute, feel free to use Swords Dance until the Substitute breaks. Once the Substitute is broken, repeat the process until the Salac Berry activates, then Garchomp is ready to sweep. Dragon Claw allows Garchomp to switch attacks, ensuring that Garchomp is not stopped cold by most Steels. Outrage is still a worthwhile secondary choice, however. Because Garchomp will be at low HP after the Salac Berry activates, Outrage is worth considering due to its higher Base Power over Dragon Claw. Even with a Swords Dance, there are a number of Pokémon Garchomp will still be unable to KO with either of its other attacking moves. Outrage offers the strongest alternative possible, at the risk of being walled after using it. Whichever Dragon-type attack you choose, Earthquake is the best move to pair with it, offering the most additional coverage and STAB. Stone Edge isn't worth considering on this set; you lose the guaranteed OHKO on Lugia, but Dragon and Ground offer far superior coverage than any other combination, and you still maintain a slim chance of OHKOing Lugia with Outrage after Stealth Rock damage.Team Options & Additional Comments >>>
Garchomp's movepool isn't massive compared to other Uber Pokemon. The moves listed are best choices for Garchomp in most scenarios.
On the Choice Band or Choice Scarf sets, Crunch is a reasonable option over Stone Edge. Crunch can still 2HKO Lugia on the Choice Band set, while giving Garchomp a safer alternative against the omnipresent Psychic-types in Ubers. Given that Garchomp has better overall defenses than Swampert, running a defensive set that utilizes RestTalk or Stealth Rock may seem like a viable option, but Dialga is generally the better choice for this, as Dialga has no 4x weaknesses and has better defenses than Garchomp.
Checks and Counters
Timid Lugia is the best check for Garchomp. It can live by using Reflect, Roosting off the damage, and scaring Garchomp off with Ice Beam. However, Timid Lugia needs to watch out for Choice Scarf Garchomp's Stone Edge, as it will be 2HKOed after Stealth Rock. Groudon must invest heavily in HP and Defense in order to be a buffer against Garchomp. Unfortunately, Groudon is still at risk of being 2HKOed from a Swords Danced Outrage, while Thunder Wave will not paralyze Garchomp, thanks to its Ground-typing. Cresselia can easily switch into Garchomp that lack Swords Dance and retaliate with Ice Beam. Moonlight's recovery is boosted by Groudon's Drought, allowing Cresselia to more efficiently take hits from Garchomp. Skarmory and Bronzong can switch into Garchomp, especially because the vast majority of Garchomp lack Fire Fang or Fire Blast. Metagross can switch into a locked Outrage and KO Garchomp with Ice Punch.
Many Pokémon can rely on their high Speed in order to revenge kill Garchomp. Keep in mind that the Choice Scarf set is an exception. Mewtwo, Darkrai, and Deoxys-A carry moves that threaten to OHKO Garchomp. Mewtwo commonly has Ice Beam to dispose of Garchomp quickly and also access to Will-O-Wisp and Reflect. A combination of Darkrai's STAB Dark Pulse, Dark Void, and Bad Dreams will usually force Garchomp to switch out. Deoxys-A can easily scare Garchomp off with Ice Beam, but cannot switch into Garchomp at all. Deoxys-S can always outpace Garchomp, with enough Speed investment, and bring it down with Ice Beam. For the non Choice Scarf sets, Latios, Latias, and Choice Scarf Dragon Pokémon can revenge kill Garchomp. This can be risky though, because Haban Berry Garchomp will survive any of the faster Dragon-type attacks, bar a Draco Meteor from Soul Dew Latios or Latias. For any user of Ice Beam, 269 Special Attack minimum is required in order to OHKO Garchomp.
Sand Veil makes countering Garchomp difficult. Because Sand Veil reduces Ice Beam's accuracy to 80%, it may sometimes miss, resulting in Garchomp gaining a KO. Dark Void suffers an accuracy cut from 80% to 64%. Thankfully, Rayquaza's Air Lock prevents Sand Veil from screwing up ExtremeSpeed's accuracy.
