I assume they brought it back to Atlas either because they're repairing it, it naturally goes from kingdom to kingdom, or, much less likely, they're going ahead with the 51st tournament. "we got penny's core from amity arena once it made it back to atlas"

So it might be an automatic route.

You can also see amity arena in the final group shot of the opening.

Honestly I was not expecting it to be in the show at all. until maybe when they make it back to vale
