So you are saying you need multiple ways to beat Garchomp in order to make a correct, successful team? In the RMT forum, raters are not suppose to use the "If X dies, then Y sweeps you" mentality, however you are encouraging people to address this.
That's exactly what I'm saying, keeping in mind that this applies to a whole lot of other pokémon as well. It's even the downfall of many a stall team, who tend to overly rely on Blissey to sponge special attacks and then get destroyed by Empoleon or Latias when it gets blown up by Heatran or Magnezone. Maybe they should replace that Swampert with a Suicune instead. Two or three usable checks is better than a single strong counter, as it's all too easy to overload a single pokémon with defensive duties or the opponent could be carrying a move to lure in and defeat the pokémon you thought would counter it.
The idea of a "counter" for half of the upper tier of OU is almost laughable these days anyway. Salamence, Tyranitar, Jirachi, Kingdra don't have any real counters at all. Many others only have a single good one, such as Cresselia for Infernape, or shaky ones like Blissey for Latias or Empoleon. (What if Latias Trickscarfs it or has CM/Refresh? What if Empoleon is running a Swords Dance set?)
And dont be ridiculous Tentacruel, Roserade or Forretress are nowhere near as easy to use as Tyranitar, Scizor or Metagross.
Ease of use is irrelevant, though I wouldn't say Roserade or Forretress are very difficult to use at all. All that means is more people probably use them, which says nothing about how good the pokémon actually is. Kingdra isn't easy to use but it's the most dangerous pokémon in OU when supported and used properly.
Reflect on Rotom doesnt even work particularly well against Chomp. Chomp has swords dance and reflect does nothing to prevent Chomp sweeping you next time..
Rotom can Reflect on the same turn Garchomp uses SD, so Garchomp still deals 100% damage. If Garchomp uses SD again next turn it's only dealing 150% damage (300%/2), instead of the 200% damage it'd be dealing with +2 attack and no Reflect. That is to say, Reflect decreases damage better than SD boosts it, as attack boosting suffers diminishing returns. Reflect is a good move in general and does a good job of scaring off Garchomp, who is basically a pure sweeper and totally doesn't like its damage being neutered like that. Burn does that too, actually, but Reflect can't be blocked by an opponent's Substitute and doesn't miss...
The fact is to prepare for any other threat usually takes about 1 and a half pokemon. Pert + Scizor and Salamence wont sweep you. Pert + Scizor and SubChomp can 27% of the time, Yachechomp like 36% (actually this is way higher, since pert doesnt do enough with icebeam against yache for scizor to finish it off). Pert + Scizor + Latias makes you mostly safe against Yachechomp but it doesnt change the figure against Subsalac (unless it's a scarf latias I guess).
On average, YacheChomp will be put in CB Scizor's Bullet Punch kill range from SR + min SpA Swampert Ice Beam. Ice Punch comes very close (boosted Avalanche would obviously do it by a mile) and even minimum attack investment can guarantee it, which isn't that difficult since a mere max HP is enough for Swampert to survive +2 Earthquake. Yache is more useful if Scizor ain't lurking back there, or you can actually manage to set up at 80%+ (like early help from Sand Veil) and survive a mid-sweep Ice Shard.
Anyway, yeah that sounds about right if Swampert + Scizor is
all you have to possibly beat Garchomp, nevermind any possible support moves or any other pokémon that outspeed Garchomp or avoid a +2 OHKO. Those two work better against Salamence, as Scizor hurts it a little more and it doesn't usually carry a Yache Berry for Swampert's Ice attack. But how about we take a different "one and a half" pokémon like, say, Skarmory + Latias? Salamence hits Skarmory a lot harder with Fire Blast and it outspeeds non-Scarf Latias with a DD. Skarmory is an annoying pest for SD/three attack Garchomp and completely stuffs all over sets, plus its Spikes support wears Garchomp down the way SR usually wears down Salamence.
Of course, even disregarding other pokémon, is it a big deal that Garchomp sweeps a team with Swampert/Scizor (with no other Garchomp checks, direct nor indirect) about 1/4 of the time? 27% of the time... if you're even using Sand Stream. Only about 30% of teams, at least in Stage 3-1, used T-Tar together with Garchomp, plus minimal Hippowdon usage. (Between any two players
with Garchomp, Sand Stream active only ~55% of the time. Overall, it's less than 50%.) 27% of the time... if you're using a Sub/SD set. The most popular Garchomp dons Choice Scarf and roughly half of them use either Scarf of Band! And yeah, where Scarfchomp is used as a sweeper of sorts, it's a completely different beast from SDChomp and ultimately much more counterable. Only about 30% of the SD sets use Substitute, without which the sweep chance goes down slightly from your approxiated 27% chance. So while a particular Garchomp set might have a 1/4 chance of sweeping me at-will, any given Garchomp I see only has a ~6% chance to do so. (They may still sweep with luck not related to Sand Veil or simply through intelligent play.)
A bulky water with hp electric and Gyarados wont sweep you.
Gee, that seems awfully specialized to me. HP Electric Vaporeon serves absolutely no other purpose but to counter Gyarados, since it certainly doesn't do enough to scare any other Water except maybe offensive Starmie. I never said Gyarados didn't have a counter, though, just very few. The real "uncounterables" are... mostly the Dragons, but other pokémon can fit the mold as well. Lucario has no "counter" by strict definition (though Gliscor is realistically effective enough) and you'd be hard-pressed to find a Jirachi counter, as an example. The Force is strong with its flinchhax and it can always U-Turn out from Magnezone or Fire Punch it.
Your team has a latias, 2 priority moves and a swampert and I have still seen you swept by Garchomp. You were unlucky, but not all that unlucky.
That was you! <3 I finally decided to not be lazy and try out some new pogeymans over Breloom. The primary traits desired are sleep user, good status absorber, and/or make a good Latias check. Garchomp is nowhere on my radar, although a Latias check that relies on >350 Speed or priority would just happen to serve as an additional Garchomp check too. Anyway, yeah, Garchomp's swept me before! Earlier, one also came in on my 25% Swampert and delivered the killing blow for the win, 2-0. *shrug* I don't win every match, Garchomp is inevitably going to be involved in some of them if for no other reason than it being everywhere. I think Latias is a lot tougher to deal with. And if I really wanted to insulate myself against Garchomp, I wouldn't use a support Jirachi with neither an Ice move nor Reflect. Need Tbolt to check Gyarados and keep Skarm from setting up too easily, though. :P
gonna split into another post, don't bitch at me for double-posting. I figure you guys are pretty tired of these super-long posts, take a break. :[
