I'm very excited to see such a great number of submissions this time! I think it's time I start giving some feedback:
The Stat Bully (
dex18): Stat drops are definitely an very interesting topic to explore, as on one hand, they're inherently less powerful than set up moves because the opponent can switch out, but on the other hand, the fact that the opponent has more counterplay to it means they're less volatile, which (at least in theory) make them more flexible to work with. I think you should check out
this old submission for CAP 26, as I think you could use a few of its ideas, particularly for your questions. That being said, we just finished Astrolotl, a Pokemon that excels at using stat drops thanks to Fire Lash, so I think that the timing for this submission is a bit unfortunate. I think this is workable if you try to put more emphasis in trying to make this particular mon use stat drops in a unique way that hasn't been seen before
Silicon (
20Yelram02): I think that it would be interesting for CAP to create a more dedicated wall, as we usually tend to create more offensive products. However, I must say that I'm not convinced that simply trying to make it have one glaring weakness would be enough to base whole process around it. Also, I'd frankly think Toxapex is just a bad example of a wall with "a crippling weakness". The fact that Toxapex lacks major flaws is one of the main reasons why it has been a dominating force since its introduction. If you want other examples, you could always use Blissey, which can wall virtually anything on the Special side, but it's very frail on the physical front.
Roadblock (
Pipotchi): I like this concept a lot. Pivoting has been an important part of Pokemon since its inception, but this generation, the advent of Heavy-Duty Boots and the Teleport buff has made them more prominent than ever before, so I think this could be a fascinating topic to tackle for CAP 28. Something I would consider changing is adding a specific mention of Heavy-Duty Boots and Regenerator to the list of strategies to shut down at the beginning of your justification, as I think trying to counter those would also add a lot to the possibilities for this concept.
Gender Roles (
JAGFL): I'm not really sure on how legal the idea of implementing gender-based abilities/stats/moves is, but I admit it could lead to an interesting discussion on how small changes can have a huge impact on the roles a Pokemon can play. Unfortunately, I think this is really a bad time for a concept like this, as the TLT wants to complete CAP 28 in three months so that we can implement it before the Crown Tundra releases, and a concept like this would require additional time to discuss the difference between each gender (as in the end, this concept should require either 2 stat submission, 2 full ability discussions, or 2 moveset discussions), and I'm not sure we can afford that.
I've Got You Covered! (
Scizivire): I think most Pokemon have the option to pick their checks, at least to a certain extent. Many past projects have discussed and implemented having different checks depending on the specific set, so I'm not really sure we have much to learn from this. Additionally, Levitate/Bulletproof Equilibra is one of the main things that comes to my mind when thinking about a Pokemon that can drastically change its checks, and while perhaps that's a bit of an extreme example, I think it goes to show how uncompetitive the idea of picking your checks can easily get in practice.
Teaching a Old Dog New Tricks (
SunMYSER): Trying to implement old tactics to the current metagame is one of those ideas that I think has been around CAP since forever. That said, these kind of ideas have been around for a reason, as I think it could definitely work for a great project. A minor nitpick would be that I wouldn't include the Gen 5 weather wars nor Gen 1 Normal-type wallbreakers as examples, as the first one was something we could replicate with just one Pokemon, and the latter would directly imply typing. If you want other examples that could fit the concept, I think Pinch Berry sweepers and Explosion users could be good ones.
I'm No Lazy Weakling! (
Ducky Mioda): Combining the roles of defensive pivot and wallbreaker is an interesting idea, but as quziel already said, this is currently lacking in direction, as terms like "wallbreaker" and "utility counter" are way too broad, I think that adding a few question about the possibility of using different status moves and other possible tactics. Also, mentioning that it'd be specifically designed to tear down every single wall in the CAP metagame by using both Physical and Special moves is not a good idea at this stage, as it's still way too early to decide that CAP 28 will beat
all walls, and there's no reason to pigeonhole us into a mixed attacker (and the OP of this thread already discourages including physical/special bias into concepts).
Practicing One Kick 10,000 Times (
snake_rattler): Simply a great solid submission. Not much else to say about it other than I think it can lead to a great final product, and I don't think there's any real risk of this turning into Dracovish 2.0, as I believe that everyone on the TLT will be doing their best to prevent that outcome.
Gun Fort (
quziel): Another overall well constructed submission. I guess if I wanted to nitpick anything, it would be that CAP doesn't have a great track record when creating set-up sweepers, but I'm pretty confidant we can execute this concept without too many issues if we take it seriously.
Paste Eater (
-Voltage-): Studying how certain common cores work and how to dismantle them is certainly a very solid foundation for a concept. I think I'd like to see a few a more concrete examples on how we could implement this concept, because right now, I'm not sure how we would build this without either being broken like Dracovish or overspecialized like Plasmanta.
Ahead of the Curve (
G-Luke): Priority has always been an interesting topic in Pokemon, as it can turn a matchup on its head by allowing the slower Pokemon to attack first, and thanks to the myriad of priority moves available, there's a very healthy amount of options we could mix and match for this. A small nitpick, I'd change exploit in your description. as it makes it ambiguous whether you are using the priority moves or you are punishing the opponent for utilizing them.
Form and Function (
Darek851): As I said before, this is an illegal submission, as this would require adding custom elements in order to work. Abilities like Zen Mode or Stance Change wouldn't prevent this issue, as they're hardcoded to only work on Darmanitan and Aegislash respectively. and would not work if you gave them to any other Pokemon.
No STAB? No Problem! (
Slapperfish): This is an interesting idea, but I think that if this that you should establish from the start that a Pokemon not learning any STAB moves is a strict disadvantage as there's no good reason why something wouldn't want to have the option to run STAB moves, even if it wouldn't use them in practice. If you take this into consideration, you could base the rest of the concept around trying to compensate for that flaw, instead of somehow trying to turn it into a positive, which I don't think it's realistic.
Patience Is The Key (
Gekokeso): Having to play around negative sounds like an interesting challenge, although I'm not completely sure there are enough good ones to have an interesting discussion. Also, if you want to make a concept around I really think you should try yo discuss some other interesting moves to explore like Avalanche, Revenge, Beak Blast, or Focus Punch, not just Circle Throw/Dragon Tail.
Boxing Gloves (
Rabia): Overly optimized typings have been a feature of CAP ever since Syclant. Because that stage comes first, there is little incentive to pick anything other than the most optimal combination, as later stages can always be scaled down if power becomes an issue. This fact alone means that this concept should prove to be a very interesting challenge for the whole community, and could lead to a very fun unique product. Something I would put more emphasis on your questions is trying to establish a clearer definition for bad typing, as I think that can vary a lot depending on how we would define it.
You're Going Down With Me (
Knight who says "Ni"): Given that I submitted a
similar concept for CAP 27, it should come as no surprise that I like this idea, especially if you were to flesh it out more. I think you would benefit a lot from taking a few notes from my past concept, in particular, the questions regarding what is the most optimal time for sacrificing yourself and how can we affect the game even after leaving the field could add a lot of depth to your concept.
In case I haven't covered your concept yet, don't worry, I'm planning on giving another round of feedback tomorrow. I'm really liking the discussion until now, so let's keep it up everyone!
