With ability spam, it truly didn't require any skill; Players could just make one decent set, press (Ctrl+C -> Ctrl+P) 5 times, and come out with a "solid" team that could actually deal damage. That was nonsense, but we handled that. From your post, it is rather apparent that, because all six of a player's Pokemon are (x), you assume that team to be uncompetitive and unintelligent in nature... However, let's run a brief thought experiment.im really not sure what makes ability spam problematic for you and not species spam because theyre pretty much the same thing.
If there was a team that had two Hoopas in it, would you consider this to be problematic? From the looks of your post, and from the other comments arguing in favor of a clause, the answer would have to be "yes". However, if we substituted one of those Hoopas for an XTwo, the consensus seems to be that this would be fine, judging from this:
This immediately tells me that this problem is purely relative, and superficial in nature. It's not about balance, it's about optics. Having two Hoopa-Us on a team is "threat-stacking", "spam" and outrageous, yet replacing that second Hoopa for a Pokemon that's better than it in nearly every way, is completely fine since now it's no longer "spamming". Being forced to utilize a wider variety of Pokemon doesn't automatically make things "balanced", nor does it raise any sort of "bar" for the format. It simply restricts team building options with no benefits to show for it. If somebody really wants to spam Pixi-sets or brute-force walls as such, they're going to do it regardless of who's face is leading the charge. Species Clause isn't going to magnify the meta or its Pokemon, rather, it'll do the exact opposite and turn everyone into functions. Now, rather than having Pixilate XTwo and SashSmash XTwo, you'll just have [pixilate mon], and [sashsmash mon], and many of these teams will likely achieve effects similar to the ones you were trying to prevent... Pro-banners will still be annoyed per tradition and pursue the next suspect, whilst killing part of what makes BH into the wonderful, surreal experience that it is.?????? there are a ton of viable psychic types that can fill the same roles as mmx or mmy in case you still want your precious psychic spam in a species clause meta. mega zam, mega gallade, deoxys-a, medichamite medi, mega gardevoir, mega metagross, hoopa-u, ultra necrozma are all usable psychic type breakers/sweepers, and a significant portion of them can go mixed.
There's no hostility intended by this, although there's really no other way to say it: The impulsiveness needs to stop. Not every set or strategy that's triggering is overpowered or broken. And just because a set beats a high, or even top-level player doesn't mean that its user is automatically gaining unfair advantages by from their strategies. Different players will inevitably have different playstyles and approaches, and not even the greatest players will be able to Catch 'Em All. This reality has existed for as long as Pokemon games have. You're never going to have a 100% win streak forever. You will lose, sometimes humiliatingly so, and it'll likely happen more than once, but not even that's a good enough reason to invoke the banhammer.
Let's stop rushing to remove everything we don't like. Let the meta develop, and allow it to change.
