Since this claim has been used to defend Tera: do y'all even see the current metagame as "creative"? Like, it's still early so I'm sure this statement will age poorly, but I feel like we've explored the vast chunk of what Tera offers from a "creative setbuilding" perspective. Tera can be used to:
- Boost STABs
- Give mons whatever offensive type they want
- Resist moves
- Grant immunities to status effects
- Spinblock with Tera Ghost (or if you're super afraid of Glimmora specifically, Tera Poison/Steel)
#1 is not really creative at all, it's just a bog-standard offensive boost. #3 is interesting insofar as choosing what you resist is a somewhat difficult problem (like Zoroark gimmicks on steroids), except most people have gravitated towards the same general types for defensive play — Fairy, Steel, Water, Poison being the big ones I've been seeing. It does open up creativity insofar as you can change what Pokemon your defensive mons check on-the-fly, but it doesn't really do so in a particularly exciting way (it's not like Z-moves where some came with cool abusable effects). #4 probably has the most creative potential, but right now it seems very niche; maybe someone will start running Tera Fire or Electric on a set-up sweeper to block burns and paralysis respectively, but I haven't seen that. #5 is even more niche, and while it was a cool concept initially, the fact that basically every lead can do it makes it feel more like it homogenizes gameplay rather than diversifies it.
That leaves #2, which in my opinion makes the game
less creative. Rather than needing to find cool sets like SubDisable or whatever to bypass your defensive counterplay, you just... smack on a Tera Blast and blow through the tier. There's no creativity involved in this process: you identify what checks you and you throw on a move that's super effective against it. I think this actively lowers the amount of creativity that goes into building sets — why build a whacky Whirlpool lure for Pex when you can just make your DD sweeper Electric type? You get the gist.
Are there more applications of Tera I'm missing? Or as-yet-undiscovered angles? Since to me, the only one that seems really, well, creative is #3 (#4 has potential on paper but hasn't been tapped into much), and while I do like having more defensive counterplay to stuff, I think if your thesis is "Tera makes
defensive counterplay more flexible" then you're clearly fighting a losing battle considering the best Tera abusers are currently offensive mons using it to eliminate defensive answers, not enable them.
[Edit: I guess something I didn't mention is using Tera to get around trapping? Like a Steel type using it to escape Magnet Pull, or anyone Tera'ing into Ghost to escape all trapping. This is definitely a thing, and maybe will be more relevant later in the generation, but I haven't seen anyone mention it yet — hence why I only just realized it's something that can be done.]
Admittedly, though, the rest of the metagame doesn't feel much better — a lot of mons right now feel like fakemons designed to minmax one or two traits, and they just end up running the "obvious" sets. I mean, two of our banned mons had massive speed and special attack stats, near-unresisted STAB coverage, and an ability that boosted their stats even more. The two Donphans are basically "what if the 'offensive tank' archetype that new players think exists in singles actually did exist?". Espathra is literally everything you could ever want on a Stored Power abuser — CM, Speed Boost, Psychic STAB... Cyclizar is nearly every utility pivot move smacked onto one Pokemon, and then it was given good defensive typing and Regenerator. Like, these sets genuinely build themselves.
I'm sure that, with time, some more creative strategies will be uncovered, but man if the current state doesn't feel uninspired. Normally the beginning of a generation is a time of experimentation (remember the insane diversity of Fini sets when it was first released? remember SpDef Alowak?) and it's really concerning to me that the new Pokemon designs just... don't offer that.
