Before expressing how the games never banned "broken" Pokemon like Galarian Darmanitan or Dracovish, keep in mind the official competitive format often caters to the Doubles Format over the Singles Format as seen in how the Doubles Format dominates VGC, many new items and abilities are clearly leaning towards Doubles, and that seemingly "broken" sweepers in Singles are far more vulnerable in Doubles suggesting that GameFreak did not think Single Battles in mind when designing Pokemon like Dracovish and Galarian Darmanitan. In fact, if you look at the banlist above, some of the Pokemon are known better for being far more effective in the Doubles Format than Singles. With that being said, this is an explanation, not an excuse to avoid the discussion of Single Battles. The games' favoring of Doubles over Singles will affect the Single Battles format greatly, so with all this knowledge in mind, please go ahead and discuss your thoughts on how this will impact Singles & Doubles.
I also want to point out that there's a very good reason why Dracovish and Galarian Darmanitan did not make the top 10 in either single or double battling: These are not full-team battles. When you're battling with a full team, especially in single battling, there's going to be a lot more switching, particularly at the beginning, as you have a lot more options. In single battles, you begin with only 3 of your Pokémon, so you not only have fewer options, but switching is a lot riskier, because a badly-predicted switch at the beginning of a battle could potentially take out one-third of your Pokémon.
Both Dracovish and Galarian Darmanitan are centered around the Choice Items, which allow you to make another selection upon switching out and switching back. When you have your whole team to choose from, the inability to pick another move until you switch out and back isn't really that bad of a drawback. On the other hand, with only three Pokémon to begin with, that's absolutely crippling, more so when your Pokémon are knocked out. When one Pokémon is knocked out, you have one other Pokémon to switch to, which won't always be a good matchup against what's on the other side. When two are knocked out, you can't switch at all, and you have to fully commit to that move or, if you haven't used it already, use Dynamax to be able to select something else for the next three turns, then get locked back in.
In addition, Dynamax itself really hurts these two, since, as Pokémon who rely on Choice Items, they should not be Dynamaxing unless as a last resort. Whatever they're up against, odds are they can Dynamax with impunity, allowing that Pokémon to withstand a hit (as long as they're not weak to something) and strike back with something strong with a powerful secondary effect.
For a similar reason, you don't see Toxapex on that list despite being some Smogon players' worst nightmare because Toxapex relies on Regenerator via switching out and back in, which is less useful for 3-on-3 battling. On top of that, due to low attack power and having few attacking moves, Toxapex is ill-suited to use Dynamax, and Baneful Bunker won't stop Max Quakes, Max Mindstorms, Max Lightnings, and their G-Max counterparts from getting through and applying their effects, and won't apply Poison either because Max Moves and G-Max Moves are non-contact.
Initially I was ticked off that My new Favorite Pokémon Cinderace was on the Ban List for the next 2 months but then I remember how I was disenchanted by competitive battling due to only seeing a handful of Poke’s on the top teams and VGC series. While I still might play ranked a bit without my Cinderace just to get the Rewards for Pokeball Rank I’m just not a fan of having to build a whole new team from Scratch multiple times every generation just to stay competitive. I tend to get very attached to my Original Team I build during my play through and the 2nd team I build from the ground up to be more competitive. Of course if you listen to the talks in game and watch the anime that’s what it basically teaches you.
You might have to stop playing Ranked before long, because if this is like Generation VII, Series 6 will be followed by an even wilder ruleset for Series 7. What they're doing now is relatively tame.
