I love the idea of a trick room team, as most of my runs turn into them, it's just such a shame that the AI doesn't work with it. But I say to keep it as a double battle for now, because there's more options, and it makes it feel more chess-like for me. How about a double battle calm mind team, and have his mega be something like mega alakazam. And maybe, if the AI gets fixed one day, maybe we can have a combination of the two and have him have something along the lines of a calm minding mega slowbro with trick rooms set up. I think in a perfect world, that would be a great fight.
