Viability Rankings
Welcome to the first edition of the Generation 9 National Dex Viability Rankings! In this thread, we as a community, overlooked by a unique council, will attempt to rank every viable Pokemon in various ranks. Please be encouraged to post your thoughts on the viability of Pokemon in this thread!
Ranks
Pokemon will be ranked in descending order; there is no divide in viability inbetween ranks. There is no differentiation in offensive and defensive Pokemon. Toxapex may be A+ for its defensive utility, while Hydreigon may be A+ for its capabilities as a wallbreaker.
VR Council
The VR Council is made up of respected and active users in National Dex. They will have the final say on where Pokemon get ranked. Here is the current VR Council:

Guidelines
There are some guidelines to keep in mind before posting here. We want to foster intelligent discussion, not unfounded arguments. Please keep these things in mind:
- Posts like "I think X Pokemon should be in Y Rank" will be deleted; make sure to back your opinion with facts and an actual analysis of the metagame.
- Adding onto the above, I would simply like to point out that, while usage stats may be used to support your argument, they should not be the basis of your argument. Saying something along the lines of "X Pokemon is not used often, so it should drop" or "X Pokemon is used very often, but it isn't ranked very high, it should rise" are not valid arguments.
- You shouldn't merely state the obvious things either. We know that Galarian Darmanitan has access to a very strong STAB Icicle Crash combined with good coverage options. We are far more interested in knowing what meta trends may favor Galarian Darmanitan.
- Replays are mandatory to support a nomination if a Pokemon is Unranked.
- This is not the place for personal attacks. Not everyone agrees on the viability of Pokemon, and that is no reason to attack them. Any posts that do attack users will be swiftly deleted and met with an infraction.
- This is not the thread to talk about suspect tests. One liners also have no place here. Both will be deleted and may be met with an infraction on repeated offense.
Barraskewda sdouldn't be in A- rank.Barraskewda is highly repetitive to floatzel and Basculegion. Both floatzel and Basculegion have a way much higher-powered wave crash compared to Barraskewda's liqiudation. The only advantage of Barraskewda is the mere speed and attack advantage.
First, the speed.
By comparing the speed of Barraskewda, floatzel , and Basculegion(speed IV 31):
Barraskewda 252speed3(under rain there is no need for +speed nature)-371(under rain 742)
Floatzel 252speed-329(under rain 658)
Basculegion 252+speed-255(under rain 560)
Compared with other fast pokemon:
+1speed 252+speed greninja-565
+2speed ceruledge 252+speed-590
quark drive 22+speed iron boulder-571
252+speed choice scarf tapu koko-591
252+speed choice scarf weavile-523
252+speed choice scarf tapu lele-475
quark drive 252+speed iron valiant-546
+1 252+speed dragonite-426
from above we can see that there is little threats that have speed above 600. The slight speed boost doesn't actually show many response. Floatzel and Barraskewda basiclly have the same speed compared to others:faster.Only Basculegion is slightly slower taht actually makes a difference.
Next, the attack boost VS wave crash:
252+ Atk Choice Band Tera Water Floatzel Wave Crash vs. 0 HP / 0 Def Mew in Rain: 554-654 (162.4 - 191.7%)
252 Atk Choice Band Tera Water Basculegion Wave Crash vs. 0 HP / 0 Def Mew in Rain: 530-624 (155.4 - 182.9%)(why not +Atk explained before)
252+ Atk Choice Band Tera Water Barraskewda Liquidation vs. 0 HP / 0 Def Mew in Rain: 440-518 (129 - 151.9%)
Very easily explained how wave crash is stronger than the attack boost
Another problem is that barraskewda is actually frailer.
Barraskewda has a bulk of 61/60/51
floatzel has a bulk of 85/55/50
Basculegion has a bulk of 120/65/75
having a better bulk means being able to survive more hits and do more damage. There is no restriction on that floatzel and basculegion must use wave crash. Better bulk also can help to not be OHKOed by priority moves better
Finally the typing. Both Barraskewda and floatzel are pure water, while basculegion is a water and ghost type. So what we are comparing is how a ghost type benefits more. You get a fighting and normal immunity. This is very good at preventing priority moves such as Extreme Speed and Mach Punch
By comparing how Barrasweda is to floatzel and Basculegion, it is ovious Barrasweda shouldn't be in A- when Floatzel and Basculegion isn't even on the list.
Last word: if you don't agree with me, yo can discuss friendly-don't be mean: I did a lot of comparision to get to this.
