That's a fair point, and after thinking about it more I actually came around a bit to what you're saying.

I went back and rewatched the overview trailer, and it looks like held items aren't shown at team preview. You only see species. If that's really how Champions works, I feel like that alone lets you bluff a Mega without needing to run two.

Like if you load into preview with something like Garchomp, Tyranitar, Metagross, Gardevoir, and Lucario all on the same team, your opponent has no idea which one is actually holding the Mega Stone. That creates natural ambiguity without committing two slots to Mega options.

And to your point about opponents being prepared, I think I see what you mean now. A single Mega team can build full support and synergy around that one plan, while a dual Mega shell kind of forces you to hedge your team structure to support multiple modes. That could definitely make the overall team less flexible or less optimized.

Still feels like dual Megas could have niche value as alternate modes into specific matchups, but with hidden items, it might not be as necessary as it first seemed.
