A deeper issue
As caird explained, the main issue is that the challenge is unclear because its rules are currently not fully self-contained, which means it's not yet in a state to re-open. (Your edits automatically put it in a reopen vote queue.) A black-box verifier on another site is not suitable -- we require that all information needed to confirm a solution as valid is written in the challenge text itself.
I see, however, a deeper issue lurking. Even if the challenge is clear and on-topic, I want to know "Is it fun to golf?"
(I'd usually bring up things like this in the Sandbox, but I'm posting it here as feedback somewhat beyond the question-closing you asked about.)
My first impression reading the question is "Someone is into Pokemon!" But I don't know anything about Pokemon teams, and I imagine most readers also know little or nothing. And if the challenge were edited with a full explanation of precisely what a Pokemon team is and what the stats are and what the exact Teambuilder text format is, even if this were nicely and clearly written, it would feel like work for me to digest it without knowing why I'm doing so.
The topic strikes me as a narrow reference, as if the challenge is aimed at players of Pokemon Showdown. Maybe that's fine for a niche interest among some community users, but it's far from ideal. We have lots of questions mentioning Pokemon and much more obscure themes, and they try to be written as challenges that anyone can access and appreciate in golfing without prior knowledge.
Where's the beef?
Which brings me to question of, is this really a golfing challenge? It seems like solvers are meant to think a lot about Pokemon and moves within the rules, in order to find ones that are short and compressible or in a golfing language's built-in dictionary. This initially strikes me as a bit far from programming.
Since I don't know what makes a valid team, I may be missing what makes this interesting, and I think it's up to the challenge to try to explain it. Like, maybe the idea is that the space of valid teams is large and complex to optimize over, so we're intended to write code to do a heuristic search. We've had a number of successful choose-your-output-challenges (and a number of unsuccessful ones), where the flexibility in output gives an extra layer of golfing strategy, and different answers pick different ones suited to their language and method.
I see there are now answers posted who outputs being are really short, with one text at 16 bytes. This leaves basically no room to golf now except for the ultra-golfiest languages. In something like Python, I can't do better than print this string verbatim. So, it seems that further improvement would come from thinking more about Pokemon and the Teambuilder format. This suggests it might be off-topic for a site about programming challenges.
