Dual Kabutops Rain - How to Deal with the Metagame
I created this because it may be unclear how to handle threats of the metagame, such as Slaking. I will be going over these threats alphabetically. Enjoy!
Banette
Choice Band Banette can be beaten by Band Kabutops, especially if it's locked into ESpeed. Band Cross Chop does a lot, but it's outsped and Band Shadow Ball does more, picking up the kill after small chip. Dragon Dance Banette is one of the worst matchups for this team, as it does not have a Pokemon that can switch in easily, however Dugtrio can switch into Dragon Dance, Encore Banette, and then Taunt it. Then you can easily remove Banette due to Arena Trap.
Charizard
Charizard is annoying because our lead is Kyogre. Your best bet is to just spam Water Spout. Using Substitute is risky, because it might use Tail Glow, and if you Substituted then Volt Tackle kills.
Deoxys-Attack
Choice Band Deoxys-Attack can be dealt with using either of the Kabutops. Scouting for the move with Protect on Belly Drum Kabutops is your best bet. All of the Swift Swim Pokemon outspeed and kill it, meaning it can't force switches on Ludicolo although it does take a lot from Extreme Speed. If Dugtrio is out, beware of Pursuit. Lum Berry Deoxys-Attack is just killed by the Swift Swimmers.
Deoxys-Speed
Deoxys-Speed is almost always a lead, so you just win by clicking Water Spout on Kyogre.
Dugtrio
All of the Swift Swimmers win because they can outspeed and OHKO. Rayquaza wins because it's not only Flying-type but it can also OHKO with Aeroblast. Kyogre wins because Water Spout cleanly OHKOs. Dugtrio just does not have a good matchup.
Dusclops
Dugtrio just traps and removes it. It can Substitute and then EncoreTaunt and Dusclops can do nothing.
Exeggutor
If Sun is up, go to Rayquaza, as Exeggutor never really carries coverage for it. If Rain is up, you can go to both Rayquaza and Ludicolo, who outspeeds and can Spore, set up on, and revenge kill Exeggutor.
Gardevoir
Really annoying Pokemon, your counterplay depends on what ability it copies. If it copies Drizzle Water Spout it, if it copies Swift Swim go to Rayquaza and Aeroblast it, if it copies Air Lock go to Choice Band Kabutops and use Shadow Ball, if it copies Arena Trap Encore-EQ it. You do not want it to copy Swift Swim because it outspeeds Ludicolo and ties with Kabutops so if Rayquaza dies you end up fishing for speed ties.
Groudon
If it comes in that means sun is up, which is bad. Most Groudon are Dragon Dance which means they just Rock Blast Rayquaza to death. The play is to go into Kyogre, resetting the weather, and then clicking Water Spout. Dugtrio unfortunately cannot EncoreTaunt Groudon as it outspeeds Dugtrio at +1. In the rain Ludicolo can win.
Gyarados
Both Kabutops can kill Gyarados with Rock Blast. Choice Band is preferred due to Intimidate.
Heracross
Heracross is usually used as a lead, so just Water Spout it and it dies.
Ho-oh
Ho-oh has a very poor matchup vs Rain and every member on this team bar Ludicolo beats it. However, it does wall Ludicolo.
Hypno
Kyogre just Water Spouts it to death, plus it can Substitute on Hypno and it can do nothing. Hypno does not a good matchup vs anything, as it can be set up on, get Tricked a Choice Band, or get trapped and EncoreTaunted.
Jirachi
Most Jirachi are Choice Band. Earthquake Rayquaza deals with it easily. Both Kabutops are also good at dealing with it. Belly Drum Kabutops can scout the chosen move with Protect, and Choice Band Rayquaza can outspeed and deal heavy damage with Earthquake.
Jumpluff
Usually Jumpluff is a passive Pokemon, using Substitute and a boosting move and then Baton Passing these to a team member so that they can sweep. The best way to deal with Jumpluff is to use Rock Blast against it, thus removing its Substitute and hurting it at the same time. This is especially useful if Jumpluff has used Belly Drum. If it's a random attacking set, go to Rayquaza and use Aeroblast or Ice Beam.
Kingdra
Very difficult matchup. Kingdra outspeeds Kabutops and Ludicolo, has Dragon STAB for Rayquaza, and we are unable to hit it super effectively. We have two options: go into Ludicolo who can't do much back unboosted or go to Rayquaza who dies to Dragon STAB. If Rayquaza is in Kingdra just sort of dies though as it doesn't outspeed Rayquaza. Be very careful around Kingdra.
Kyogre
Ludicolo 4x resists Water and can get a Tail Glow out of it too. You don't even need to Spore.
Lanturn
Lanturn is actually not that good. It is hard checked by Rayquaza and soft checked by Dugtrio and the Swift Swimmers. I anticipated this matchup as harder than it actually was.
Latias & Latios
The Lati twins are natural anti-weather Pokemon. The way to win is with Rayquaza or Choice Band Kabutops, if you have Shadow Ball. However, Kabutops may have trouble switching in depending on coverage. Rayquaza definitely needs to be careful because of Dragon Claw and Ice Beam. Another bad matchup, but not as bad as Kingdra.
Ludicolo
An annoying Pokemon because you can't just use Kabutops to win unlike other weather abusers. You just die if you try that. Rayquaza can come in but must beware of Ice Beam. If Rayquaza dies you just lose.
Lugia
Both Kabutops have Rock Blast. Rayquaza has Trick. Dugtrio has Taunt. This team came heavily prepared for Lugia, as it is one of the strongest Pokemon in the meta, so it's not really a threat.
Machamp
Rayquaza comes in for free and Aeroblast kills it easily.
Magneton
Despite its Electric type, the matchup against Magneton isn't so bad. It walls Ludicolo and non-Earthquake Rayquaza, but falls to Kabutops and Dugtrio, and cannot switch in to Kyogre.
Mewtwo
Lead Mewtwo takes around 95 health from a fully powered Water Spout. If Mewtwo attacks with Psychic, use Recover the following turn, as it does less damage than you can heal. If it's not lead, then Choice Band Kabutops 2HKOs it with Shadow Ball, and both Choice Band users can use Trick to make its coverage more risky. It is still a dangerous matchup in which you can be swept, but it is manageable.
Ninjask
Every member on this team can deal with Ninjask in some way. Kyogre just Water Spouts until it dies and can Substitute on it to prevent Spores, both Kabutops can use Rock Blast with Choice Band having access to Extreme Speed and Trick as well, Rayquaza can use Extreme Speed and Trick, Ludicolo can use Ice Beam, and Dugtrio can use Taunt and Rock Blast. Similar to Lugia, Ninjask is very dangerous and must be prepared for.
Omastar
Ludicolo easily deals with it due to its 4x resistance against Water and its neutrality to Thunder. Both of the Kabutops can use Earthquake against it and are faster.
Porygon2
Not really a threat to any member of the team. Even if it traces Swift Swim it's still outsped by all of the Swift Swimmers and Rayquaza. Unfortunately it runs EQ + Ice Beam which means Rayquaza can't come in and Kabutops has to be careful.
Quagsire
Ludicolo comes in for free and Tail Glows because there is no way that Quagsire is staying in.
Raikou
Kabutops and Rayquaza deal with it. Dugtrio can come in on a sack and trap it.
Rayquaza
Another natural anti-weather Pokemon. The main way to deal with this Pokemon is to send out Choice Band Kabutops and use Rock Blast. Trick will fail if it's a Choice Band Pokemon, and Rock Blast will hit it hard. If Rayquaza has some weird set like Choice Band Aeroblast/Ice Beam/Earthquake/Trick then you just lose. That never happens however.
Regice
Rock Blast users take care of it. It's especially helpful for Kyogre to pass a Substitute.
Scizor
Scizor is annoying because its typing blocks EdgeQuake but you can probably just Belly Drum on it.
Shedinja
Every member of the team can beat Shedinja except for Kyogre and Ludicolo, and Kyogre can pass Substitutes.
Skarmory
Kyogre can Substitute or Water Spout. Rayquaza can Band Trick and Choice Band Kabutops can also Band Trick. Dugtrio can Taunt it, but unfortunately cannot trap it.
Slaking
Immediately switch to Kyogre unless you're capable of killing Slaking or bringing it to below 50% of its health. Slaking copying any other ability is deadly. If you let Kyogre die earlier in the match, go to Dugtrio. If Slaking gets a sweep set up, use Kabutops to revenge kill it, as they can survive one Extreme Speed. Its health will be low after a Belly Drum.
Suicune
Setup bait for Ludicolo.
Swellow
Both of the Kabutops win with Rock Blast.
Tyranitar
Even though it removes your weather, it's still going to be slower than the rest of your team. Almost always carries Dragon Dance. Every member of the team except non-Earthquake Rayquaza can win.
Umbreon
Kyogre can pass Substitutes, largely helping in the matchup, and Dugtrio can EncoreTaunt it.
Ursaring
Dealt with in the same way as Swellow.
Victreebel
Victreebel usually does not carry Leaf Blade as it is a special move, and is usually a physical attacker carrying the combination of Sludge Bomb and Earthquake. Rayquaza can defeat it easily and Ludicolo can revenge kill it. Special Victreebel straight up 6-0's.
Wobbuffet
Kyogre can Water Spout Wobbuffet to its doom. Kyogre can force the opponent to sacrifice a Pokemon or use Baton Pass to escape. Belly Drum Kabutops can set up on it. Choice Band Kabutops and Rayquaza can Band Trick Wobbuffet, ruining it. Ludicolo can set up on it. Dugtrio can EncoreTaunt it. All in all, the team has a pretty good Wobbuffet matchup.
Zapdos
Seemingly, Zapdos is more difficult to kill due to the Ground immunity. However, this has opened up a new Rock and Ice weakness, making everything supposedly walled by the Ground immunity (Kabutops, Rayquaza, Dugtrio) have the ability to hit Zapdos super effectively. Plus, Ludicolo can hit Zapdos super effectively with Ice Beam now, makings its matchup even worse.
