pika pal response, one, I'm not saying you could drop Calyrex-Shadow. Two, I'm saying you totally could drop Calyrex-Shadow; tiering is not a natural state of matter. It doesn't happen by the grace of the gods. It happens because we agree on something. We agree that a certain power level can be reached, and a certain point beyond that is no longer desirable so we ban it. I think that banning certain mons is necessary because they're centralizing, but I also think that at a certain point, something will become the #1 mon in the tier, and the rest of the metagame will more or less form itself around it. Is Gambit going to be the #1 mon in SV OU? Then you have all the ways of countering it that I previously mentioned. Is Calyrex-Shadow going to be the #1 mon in SV OU? Well first of all skill issue because it gets destroyed by sucker punch lul but seriously, the point is that if Caly-S was allowed, the meta would form around it. Would it be a good meta? No, it would probably suck balls. But we gotta make the effort to remember that what we do here is artificial
Do I think it is completely unreasonable that Gambit is broken? No, I think the case can be made. I'm just saying that if you ban Gambit, the whole tier is going to crumble. If you ban Gambit, Pult and Ghold become incredibly strong. You would need to find a new Ghost resist(s). Moltres-G for OU? and then if the ghosts get banned, Enam would be next, and then Wake and then IVal... There's always going to be a point of reference for the strategies we build. Im no pro at teambuilding, but if I showed you a team with five Slush Rush mons, even if it was the best team conceptually that you've ever seen, you'd say "hey snow is not really viable this gen because a b and c". For a less goofy example, if I brought a Regen-core a la gen8, it might be a good team, but it is not a good team for the meta. When we say something is a good team, it is because it fits the meta. That's why it was so cool to see that guy who reached top500 with incineroar, dude understood the meta and found a new tool to play around it. It wasn't like a VGC incineroar set, it was a set built for SV OU. Everything is relative and like it or not Gambit is #1. I feel like something solid has been built from Gambit and banning it would be undoing the work of months
