2. Chomp is not a very good early game sweeper.
Chomp, like many of the best ou sweepers and the best ou stallers, doesn't have a true counter. .
A) There is not a single good early game sweeper in ou, except possibly chomp, if there was this wouldn't be a very fun game.
B) Thats not true, every other sweeper has a counter. Also every other sweeper is easier to revenge kill then chomp.
Also my extremely too long don't read thoughts on garchomp -
The traditional way for a sweeper to set up is to come in on something they can force out and set up on the switch. Sure the opponent could stay in and try to “play around” the sweeper but this means the defending team is doing something it probally doesn’t want to. Every sweeper can be switched into safely except garchomp. This might be exceptable if he were hard to set up (like say lucario) but he can force out huge numbers of pokemon. He is also a very good defensive addition to a team, is valuable at low hp due to his great speed, and beats tons of pokemon one on one. He resists stealth rock. His best check is himself but beyond that is is latias who is pursuitable by the number 1 pokemin in the game. He also has sandveil a broken ability that damages the game on such a great user. This is on top of being the best weeper by far.
The following is an attempt to determine based on three criteria who is the best sweeper in ou. We accept that the suspect metgame is somewhat artificial so I am going to show how well the top 5 sweepers (in my opinion) fair at sweeping the top 25 pokemon in that metagame. I will then show how well garchomp does against those same pokemon. The three metrics are how many pokemon they can force out, the number of pokemon they beat after one turn of set up, and some safe ways to not be sweep (revenge killers and dedicated counters, this is not an exhaustitative list unlike the others). Note garchomp is far better at defense so it would be expected he do worse then somebody like infernape with paper defenses.
Note in cases where it is unclear the pokemon does not score (i.e garchomp is safe if rotom does not have wow but this will not score)
This all assumes no sand-storm and both leads set up rocks-
Garchomp (SD Yachechomp)
Forces out: 13 Scizor, Heatran, Metagross, Tyranitar, infernape, lucario, jirachi, gengar, Flygon, zapdos, dragonite, Magnezone, celebi
Ko’s: 20 ( Scizor, Gyarados, Rotom, Heatran, Salamence, Metagross, Tyranitar, Infernape, Lucario, Jirachi, Swampert, Blissey, Starmie, Azelf, Machamp, Vaporean, Celebi, Magnezone, Zapdos Dragonite, (note that’s everybody in the top 10 except Latias) (note most gliscor go down as well, many of these pokes can hit garchomp and break the yache berry however that means garchomp has killed a major check to himself and usually is at 40-55%, nothing is stopping him from switching out, on the top 10 7 are cleanly outsped and ko’ed)
Defensive measures: Haban latias, nobody else come is on every move. Most revenge killers can’t beat him through the berry so it takes a combo of them to take him down. Skarm is a very good first switch as is bronzing. Latias is an excellent check and doesn’t even need a scarf.
Barbiri-Berry Tyranitar
Forces out: 8 Scizor, Latias, Heatran, Starmie, Azelf, Vaporean, Magnezone, Zapdos
Ko’s: 18 Scizor, Latias, Gyarados, Rotom, Heatran, Salamence, Metagross, Infernape, Lucario, Gengar, Blissey, Starmie, Azelf, Vaporean, Magnezone, Celebi, Zapdos, Dragonite.
Counters: Machamp, Swampert, Gliscor. Revenged killed by Scarf jirachi, Flygon and gengar. Skarmory roars it out.
Its gretest issue is that its forced to run the berry to protect itself from gengar. Still not as good as chomp and much less valuable at low hp due to lesser speed. Most importantly it has three good solid counters in the top 25 wear as chomp basically has zero.
Lucario
Forces out: 3 Heatran, Tyranitar, Blissey, (kinda vaporean, machamp, and scizor but its crippled by vaporean and holding a Lo and the other two need prior damage)
Ko’s: 16 Scizor, Latias, Rotom, Heatran, Metagross, Tyranitar, Infernape, Swampert, Blissey, Starmie, Azelf, Machamp, Vaporean, Skarmory, Celebi, Dragonite.
Defensive Measure. Countered hard by gliscor and defensive Salamence. Also loses to Gyarados and regular salamence and zapdos. Gengar is a huge promblem since it needs to crunch on the switch to beat it. Scarf Magnezone traps and kills it while scarf Rachi beats it pretty well.
Overall a very good pokemon but extremely annoying to set up since it loses to or ties with everyone. Its best value is stall finds it extremely annoying to counter and gives it loas of set up. Most of its kills are clean as well. Very good against entry hazards.
Gyarados LO
Forces out: 7 Scizor, Heatran, infernape, Lucario, Jirachi, Swampert, Gliscor, – note many are very useful.
Ko’s: 16 Scizor, gyarados, Latias, Heatran, Salamence, Tyranitr, Infernpe, Lucario, Gengar, Swammpert, Starmie, Azelf, Gliscor, Machamp, Zapdos, dragonite – note almost all are clean, beats everybody in the top 10 save rotom.
Counter measures: Has huge trouble getting through celebi and vaporean. Rotom (scarf or otherwise) beats it as does jirachi/latias; he can’t ko either any on the switch. Flygon and gengar revenge. Metagross can take a waterfall and ohko back.
Great pokemon. However he is very short lived with Lo + sr and only needs to be checked once. He has solid counters. Lefties versions don’t get as many kills but are obviously more useful defensively.
Salamence Lo
Forces out: 11 Heatran, infernape, Lucario, Metagross (kinda), Gliscor, Vaporean, Magnezone, Skarmory, Celebi, Zapdos, Dragonite
Ko’s: 21 Latias, Rotom, Gyados, Heatran, Salamence, Gyarados, Metagross, Infernape, Lucario, Jirachi, Gengar, Blissey, Starmie, Azelf, Gliscor, Machamp, Vaporean, Celebi, Zapdos, Dragonite, Magnezone
Counters: Salamence needs Lo and outrage to get those kills and therefore cannot switch out. He is easily revenged by scizors bullet punch though otherwise he is fairly hard to handle. Swampert is a decent counter but nearly suicides to do it. Offensively he is the strongest pokemon in ou and about its unclear who is better he or garchomp. However he can be stalled out of outrage, forced to accept being revenge killed and is weak to stelth rock. ‘defensively he is nowhere near as good and because of outrage and lo is easier to play around offensively.
Infernape Nasty Plot
Forces out: 12 Scizor, Rotom, Heatran, Metagross, Tyranitar, Lucario, Jirachi, Swampert, Blissey, Magnezone, Skarmory, Celebi,
Ko’s: 17 Scizor, Gyarados (maybe), Rotom, Heatran, Salamence, Metagross, Tyranitar, Lucario, Jirachi, swampert, Blissey Gliscor, Machamp, Magnezone, Skarmory, Celebi, Dragonite (watch out vs extremespeed)
Counter measures: Latias is a hard counter, as is vaporean. Starmie, Gengar, azelf can out speed and ko. Any priority really hurts, as do most scarfers. Lo rcoil takes a toll, great pokemon on offense.
So all told he is probally the best sweeper in ou albeit not by much. However he is also much bulkier then 4 of his competitors (2 are stealth rock weak with life orbs and the other two have abysmal defenses). He is by far the hardest to find a genuinely safe switch in against. He is the second fastest and beats the most pokemon one on one. He is by far the best pokemon to have on the defensive (a great lucario and tyranitar check in addition to many others. He is by far the hardest to revenge kill (only scarf/haban chomp and latias do it reliably wear as many many scarfers check the other five. He happens to have a tremendously broken ability. He is not outclassed by any other offensive pokemon in any attribute and is among the best pokemon at every role. He is simply too good to be allowed in ou.
