WHY RILLABOOM DESERVES A BAN - By an experienced teambuilder.
Not many people believe Rillaboom is broken, or think that it deserves a ban. I’m sure some people will even skip all of this explanation, just leave a “Haha” reaction, and move on. For those of you who don’t know me, I’m Pinkacross, an RMT builder and ladder player. I’ve made several creative teams that peaked very high on the ladder this generation, featuring pokemon like Flame Charge Blacephalon, Arctozolt, Toxtricity, Umbreon, and Alolan Raichu. I’ve been around since gen 6, and after having done thousands of ladder games this generation, and having constructed over 5,000 teams in my builder, I consider myself extremely qualified to assess the quality of a metagame, and see what the problems are. And let me tell you-- the biggest problem this generation, bigger than Dracovish, Magearna, Urshifu, Spectrier, or even Cinderace-- is Rillaboom.
This isn’t because Rillaboom is singularly better than any of these pokemon. The reason Rillaboom is a bigger problem, however, is the wide reaching effect its presence had on the tier. I will go over two issues I have with Rillaboom that I believe make it ban worthy: first, its crazy breaking potential, and second (and more impactfully) the extraordinarily negative impact it has had on the metagame. I will title these two segments “Rillaboom the Breaker” and “Rillaboom the Meta Killer.” Note that for this explanation, I will primarily be discussing Choice Band Rillaboom, which is generally accepted to be the leading set. Please, when you read, keep an open mind.
Rillaboom the Breaker:
What are the walls to Rillaboom? There are quite a few: Mandibuzz, Zapdos, Moltres, Tornadus, Corviknight, Skarmory, and, in some cases, Toxapex. At first glance, it would seem as though there are sufficient viable walls to keep Rillaboom from being broken. The problem is, Rillaboom severely cripples all of these supposed switch-ins. Mandibuzz, Zapdos, Moltres, and Tornadus hate losing their Heavy Duty Boots, and will often die to one or two Wood Hammers if Stealth Rock is up. On top of this, the Wood Hammer recoil is negligible due to the Grassy Terrain healing Rillaboom receives every turn. Corviknight and Skarmory don’t appreciate losing their items either, but they aren’t as negatively impacted. That being said, without leftovers, and still taking 12% from Stealth Rock, Rillaboom can force these pokemon in repeatedly and U-turn for additional chip. Furthermore, these supposed walls are relatively easy to chip with U-turn, especially considering how many pokemon Rillaboom easily forces out. Rillaboom can also Knock Off the Shed Shell that Corviknight and Skarmory run, making them susceptible to being trapped by Magnezone, a common partner.
I also wanted give my two cents on this topic. Firstly a great post! I completely agree that it is an amazing wallbreaker, probably one of the best in the tier. Knock off and U-turn are notorious for being able to punish defensive play and force progress. Glide helps so much in this effort, helping it threaten out faster mons that usually would OHKO it. With access to basically a stab move stronger than Stab Giga Impact and terrain recovery, helping it heal off chip, it is meant to be a top tier offensive presence.
However, it is important to that that the answers that you mention are still pretty reliable because it takes 4 turns and 2 switch ins and 2 predictions to get past them, first knock off, second getting rocks up and 2 turns of wood hammer. While it is entirely possible to do this in battle, it is also entirely possible to deny your opponent this or at least prevent it till late game from where it is too late for Rilla to clean up. That mon that you mention, Zapdos also has 3 chances to leave him with a parting gift.
Also there are a lot of mons that are not as crippled by knock off and are amazing checks to it. You have a lot of other options like Scizor, Tang, Amoongus, Ferro (Against non-superpower variants) etc. Corvi is something I have saved till now, but is top tier mon in it's own right and is an extremely reliable answer to Rilla outside of Zone. (If defensive answers getting trapped becomes a problem, then we have always looked at the trapper not the mon that is enabled by the trapper)
Rilla has more than sufficient counterplay. It is very good but not overwhelming.
Consider walls to other ban worthy pokemon: Dracovish didn’t cripple Toxapex, Urshifu didn’t cripple Clefable, and Cinderace didn’t cripple Landorus-- at least not nearly to the extent that Rillaboom cripples all of its walls. It’s true that running certain combinations of walls will almost guarantee you have no problems with Rillaboom. Many combinations of Ferrothorn, Zapdos, Corviknight, and Toxapex will allow you to deal with Rillaboom easily-- but forcing people to run multiple fat walls to deal with a single pokemon is not a good or healthy system, and it encourages greater amounts of stall and semistall. A healthy meta encourages balance, not fat. Balances greatly struggle to handle Rillaboom’s ability to easily cripple each of its alleged walls. That being said, this alone is not enough for Rillaboom to deserve a ban… but it’s impact on offensive builds pushes it far over the edge.
Actually Dracovish straight up 2HKOed Pex after rocks. Only Bunker variants were a check. The only other checks to Vish were Water Absorb mons.
252+ Atk Choice Band Strong Jaw Dracovish Fishious Rend (170 BP) vs. 252 HP / 252+ Def Toxapex: 141-167 (46.3 - 54.9%) -- 98.8% chance to 2HKO after Stealth Rock and Black Sludge recovery
Urshifu also 2HKOed Clef with Jab. If Clef took a Jab and switched out, it was later 2HKOed by either of CC or Wicked Blow. Buzzwole was the only check to Urshifu. Despite this Clef being one of the best answers to it just shows how broken it was but thankfully is is banned now.
252 Atk Choice Band Urshifu Poison Jab vs. 252 HP / 252+ Def Clefable: 230-272 (58.3 - 69%) -- guaranteed 2HKO after Leftovers recovery
252 Atk Choice Band Urshifu Wicked Blow vs. 252 HP / 252+ Def Clefable on a critical hit: 129-153 (32.7 - 38.8%) -- 5.5% chance to 3HKO after Leftovers recovery
Lando had no recovery and just got chipped down. It could not touch it back either as Cind was fatser and got out with U turn. The only semi reliable checks to it were Hippo and Mandi but they got U-turned out on just like everything else.
-1 252 Atk Cinderace Pyro Ball vs. 252 HP / 112+ Def Landorus-Therian: 106-126 (27.7 - 32.9%) -- 88.2% chance to 3HKO after Stealth Rock
The mons that you mention straight up broke past their checks and had much lesser checks than Rilla. There is no comparison between them and Rilla.
Rillaboom the Meta Killer:
Rillaboom has single handedly over centralized offensive playstyles in a way never seen before in the history of competitive pokemon. How? Grassy Glide. Grassy Glide is a 70 base power Grass type move that becomes priority in Grassy Terrain, which Rillaboom sets upon entering. This makes Grassy Glide a stab 91 base power move (after applying the 1.3x terrain boost). This is the strongest priority move in pokemon by far. The average base power for priority is 40, examples being Mach Punch, Bullet Punch, Aqua Jet, and Quick Attack. The few exceptions to this all have huge detriments to prevent them from being broken. Sucker Punch, a move with 70 base power, only works when the opponent attacks. Extreme Speed, at 80 base power, is given to almost no pokemon, with Dragonite and Regieleki using it best. The only stab Extreme Speed user is Linoone, a completely non viable pokemon. Lastly, we have First Impression, a 90 base power move with the enormous detriment of only being usable on the first turn. In RU, where many pokemon had First Impression, HO teams easily overcame this powerful priority move by running Protect on their sweepers. Grassy Glide… has no such nerf or condition. The only thing resembling some sort of limit is the 5-turn limit of Grassy Terrain, which almost never hinders a well-played Rillaboom. This move has had a horrible effect on diversity within the tier, as well as forcing HO and offense teams to essentially choose between 10 or so pokemon to assemble a team of 6.
Do you recognize these pokemon? If you play on the ladder often, you surely do. These are the most common HO and Offense pokemon used in the tier right now. And they all have one thing in common: They resist Grass. Whether it is 4x or 2x, all of these pokemon resist Grass. This is not a coincidence. Rillaboom has forced offensive playstyles to run pokemon these pokemon, without exception. And yet, despite Offense and HO teams spamming these pokemon, Rillaboom is STILL helpful against Offense and HO, being able to pick off weakened sweepers and 2HKO Dragapult despite the type resistance.
I would argue that this is actually indeed just a coincidence. Grass is a very sub par typing offensively. It is resisted by 8 out of 18 types. Almost half. Even other top tier offensive mons like Lucha, Kyurem, Torn T resist grass. Even the rarer offensive mons like Zapdos G, Victini, Lati twins, Dracozolt, Blaziken and Gengar resist grass (While the latter 2 still take huge damage, their resist does help them prevent the OHKO). Even niche offensive mons like Aegis, Kommo O, Celesteela etc. resist grass. Mons without resist like Lando, Lele, Koko, Weavile are also often used on offense, however they do have Indimidate/terrain change/ Priority of their own to have recourse against Rilla. Perhaps the biggest example of Rilla not being the be all end all when it comes to viability of offensive mons that you didn't mention is Chomp. It is one of the most devastating offensive mons in the tier and a top offensive mon. It has absolutely no recourse against Glide and has to take the full brunt of one. Despite this it is one of the best mons on HO.
That being said, I am not saying it has no affect on offensive mons. Crawdaunt and particularly Gyarados are two mons that would be much better without Rilla. Sand and Rain would also be better without Rilla but Rilla keeps rain in check (Honestly? Thank god for that.) and both have plenty of answers for it, former having steels and regen grasses and later having the multitude of hurricane spamming flyers with ferro waiting in the wings. There are just a handful of mons that Rilla truly pushed out of the meta and even these have lot of other flaws.
Lastly, I mean it is still very powerful. Also these mons are resistant not immune. Even a resisted Glide is stronger than a neutral Aqua Jet, Mach Punch, Bullet Punch, Ice Shard, what have you. Any priority mons will always be helpful to revenge kill weakened sweepers. It is not specific to Rilla particularly. A case can be made for it's priority being too strong but that is just the part of the metagame now and not enough to warrant a ban.
Rillaboom has done more than just completely crush creative HO builds.
As I showed in the above points, so many mons naturally resist grass/ have other forms of counterplay so you still have a HUGE selection to choose from. There may be some mons that Rilla is suffocating presence for, but saying it has completely crushed creative HO builds is an overstatement.
Below I will list all the commonly considered “OU-relevant” pokemon and playstyles that Rillaboom has harmed, and/or completely destroyed.
-
Azumarill: Essentially a dead setup sweeper, as Glide OHKOs it.
-
Kingdra / Mantine / Drednaw / Omastar / Seismitoad, and other creative Swift Swim users: Due to the presence of Rillaboom, rain is now forced to run Ferrothorn and several birds, typically Zapdos and either Tornadus or Thundurus, making all rain teams less diverse than ever.
-
Psychic Terrain teams: Rillaboom evades the psychic terrain game-implemented priority nerf by setting its own terrain. Even worse, Rillaboom’s Grassy Glide is no longer a priority move when a Tapu Lele or Indeedee switches in, giving Rillaboom a high chance to OHKO Tapu Lele with Grassy Glide after Stealth Rock on switchin. Psychic Terrain as a playstyle has been crushed by Rillaboom.
-
Electric Terrain teams: Abusers like Alolan Raichu, Regieleki, and other Rising Voltage users are OHKOd by Rillaboom with its massive power priority move, making this almost completely unviable.
-
Sticky Web teams: Partly the fault of Heavy Duty Boots, but Rillaboom pushed Webs into the non viable category.
-
Blacephalon: Despite the type resistance, Grassy Glide OHKOs after Stealth Rock.
-
Blaziken: Yep, no joke, Blaziken gets 2HKOd and takes 80 minimum after a single CC defense drop.
-
Gengar: Glide does 70 minimum. Any chip, and your Gengar is toast.
-
Alakazam: See description for Psychic Terrain teams.
-
Gyarados: Glide does 87 min.
-
Keldeo: OHKOd.
-
Nihilego: OHKOd.
-
Cloyster: OHKOd, and Ice Shard doesn’t kill at +2.
-
Other Shell Smash users like Barbaracle, Polteageist, and Omastar that would have threatened many OU teams if not for Rillaboom.
1) Rilla is definitely the biggest offender for Azu being pushed out. But Lele is equally responsible. Also there are just a lot of Dragons, Grasses, Waters in the tier that can revenge kill it. A Belly Drum mon relying so heavily on priority is always going to be semi reliable.
2) Kingdra and Seismitoad are still viable on rain and are often seen on it as well. Mantine became bad when we found out that Metronome was coded incorrectly. It can't break now. Drednaw has been bad since Dynamax ban WAY before Rilla got Glide. It just struggles to dish out relevant damage. Technically, Rilla is not even a factor in selecting Swift Swimmers. All of them are killed by Rilla so you need backup for it anyway, Swift Swimmers are solely selected on their merit in the meta game. Barra and Drednaw are both revenged by Rilla but almost no rain will go without the former while the latter is almost never seen.
As to the point of Ferro and birds. Even in gen 7, rains carried Ferro + Torn. They just have amazing synergy together. Ferro was a rain staple even in Pre Glide gen 8. I would actually argue that rain has become a lot more diverse as we have so many waters to chose from like Barra, Sesmi, Kingdra, Urshifu etc. and so many fliers like Torn, Zapdos, Thund, etc. In gen 7, rain was static, mostly Peli, Mega Pert, Ferro, Torn, Ash Gren + one more (Koko, Manaphy, Gyarados being populare choices)
3) I will give you this. Psychic terrain blocking priority can't be used for team now. The team that is going around on ladder with Lele + Espeon + 4 Shell Smashers just gets owned by Rilla. That being said it is still at least relevant for Lele as it can switch into Rilla for revenge killing it. But Rilla can also switch into Lele for revenge killing it. Neither can hard switch into each other. Indeedee is just outclassed by Lele and is not upto mark with OU's power level so that's the main reason you don't see it not Rilla.
4) Raichu is just not up to snuff with OU power level again. This is starkly visible when it isn't clicking Rising Voltage. It is still a a niche option at best. Rilla does threaten it out but it is not as crippled as Psychic terrain teams as it can just switch out and come back in again later. Rilla is the least of Regieleki's worries as the multitude of ground types take priority over it. Koko is a top tier mon despite Rilla.
5) As a person with their favorite play style being webs and having a lot of experience with it, I can very confidently say that Rilla is not what pushed Webs to unviablility. It is not partly because of boots but majorly because of boots and partly because it has never been easier to defog. TBH, Webs mostly will have have Bish or Zapdos G. Dragons like Dnite, Pult etc. are great on webs. Steels like Sciz, Aegis are also good on webs. Crawdaunt is one mon I think Rilla discourages the use of on Webs but that is a minor problem compared to major ones, boots and defog.
6) Blace is actually a bit underrated. It's sub calm mind speed boosting set is still pretty good to break defense. Specs is a nuke. The man reason it is not used is as Pult is just superior due to speed.
7) Blaziken has a lot of struggles in the tier with it's speed prior to boost, 4MSS, killing itself on it's own, lack of power prior to boost and fragility.
8) Gengar is also a bit underrated. It's Sub NP set is great. It also overshadowed by Pult due to speed.
9) Alakazam is just held back due to it's absolutely non existent bulk. Even Pex can 2HKO it with knock off. It just gets destroyed in return by every single mon that survives it's attack. Sash Counter is cheese but your best bet of getting use out of Alakazam. That set actually would even bait Rilla. That being said, nobody would fall for Counter Zam now.
10) I will give you this one too. Gyarados really is just shut down by Rilla too hard. It would most probably be a viable HO mon if Rilla wasn't around.
11)Keldeo struggles against Slow twins, Pex, Fini, Koko, Zeraora, Pult etc. Rilla is also a problem but not the only one by far.
12)Nihilego faces the problem of having no move to hit steels.
13) Cloyster is actually still used a decent bit. Also the chip required to kill Rilla is minimum. One RH hit or 2 switch ins to rocks are enough.
14) Shell Smashers have always been niche in OU. They can frequently be walled or perhaps not even get a chance to set up.
I do agree with points 3) and 10). Psychic terrain teams and Gyarados are definitely the biggest victims of Rilla. They are just borderline unviable mostly due to it.
Azu and Shell Smashers are also hindered by Rilla but they have big problems outside of Rilla already that still make them niche at best.
Webs, Rain, Electric spam don't enjoy Rilla but they can play around it.
I think your points 6) to 12) except 10) were not completely relevant. Any faster mons be it with Scarf/ priority / naturally faster can revenge these mons. This is not just limited to Rilla. You were just showing that Rilla can kill these mons too and that Glide is very powerful. They have a ton of other problems that actually prevent them from being genuinely good in OU. Rilla is not the reason they aren't OU.
This list only includes the previously OU-relevant pokemon that Rillaboom has shut down. Essentially every single lower tier offense pokemon has also been shut out by Rillaboom. Never has a single pokemon so greatly killed the diversity and creativity of a tier. This is truly what puts Rillaboom past the line of banworthiness. When building any kind of offense team, you must strictly conform to very standard guidelines, or just have a mediocre, poorly functioning team that struggles against Rillaboom
As I said above, all these mons are not solely shut down by Rilla and have other flaws as well. Also not all these mons were OU irrelevant.
Another overstatement of Rilla shutting out every single lower tier offensive mons. There a ton of lower tier mons like Kommo O, Toxtricity, Diggersby, Mimikyu etc. which can still be used in OU. They are mediocre that's why they aren't used often not because of Rilla.
Again, it has not killed the diversity and creativity of the tier. There are still a ton of mons viable on offense. There are only a handful of mons that Rilla has pushed out on it's own.
That is true for any team style. There are so many threats running around nowadays that you have to keep in mind some big ones. Standards are considered good because they can go toe to toe with a majority of what you will face.
Thank you for those who took the time to read my explanation, and I hope you now see why Rillaboom needs to go. We’ll lose one pokemon if we ban, yes, but we will also gain several new playstyles, and once again be able to use a sweeper that doesn’t need to resist Grass. Please show support and petition the council to give Rillaboom a Suspect Test, and take back offensive team building! :)
I mean a lot of playstyles will become better, no doubt, but we will only gain back Psychic Terrain teams which is still gimmicky. All other playstyles are either already viable (like rain, sand, screens, etc.) or will remain unviable even without Rilla (Webs, Trick room, Electric Spam, etc.)
We would gain the ability to use sweepers not resistant to grass but that is mostly only relevant to Gyarados. There are not many other sweepers without grass resist that I think will rise to OU without Rilla.
Well, thanks for reading my post. I do agree that Rilla is very annoying and a cheap mon. I actually can even see where people are coming from when they say that Rilla is broken but it just doesn't seem broken to me. The biggest hinderance of it is that grass is just too bad offensively. That sole fact keeps it in check in my eyes despite having such a broken mechanic.
