I actually like the idea of Skill Swap, since it'll be so trollish when used alongside Illuminate, but I fear it'll end up just being a gimmick, since Illuminate doesn't really hinder anything and the pokemon gets his ability back when it switches out. Allow it, there is no harm it can bring, honestly.
as for Ingrain, it's flavorful, but has the same usefulness as Aqua Ring which we already have allowed. The only reason people would say not to allow Ingrain would be because using Ingrain and Aqua Ring could be broken (though, it's not imo) so Allow Ingrain, and if the only argument against it is that it's too powerful with Aqua Ring, then I suggest moving Aqua Ring to disallowed and Ingrain to allowed because it makes more flavor sense (and does basically the same thing.)
Calm Mind Sounds exactly the kind of set up move Mollux would use, it boosts it's Better Defense and sky-rockets his S.Atk to great levels even without that much investment. I say allow it
