Okay, I slept on it, and while this deck does some cool things, there are also a number of awkward aspects to it that are simply unavoidable, so I don’t think it’ll ever do everything I want it to, regardless of how I pilot it. I think it’s still pretty good, but not as robust as I’d hoped, and I think you’ve figured out how to counter it at this point.
I think a better version of the Glaxx engine would be [Law/Truth]/Future, as having an abundance of $3 units means there’d almost always be some juicy targets for Insurance Agents, the draw power, economy boost, and spell fetching ability Law brings to the table would make Free Speech and Assimilate more consistently available, and being able to Manufactured Truth units into Mirror Illusions would allow Quince to permanently convert tech 0-I units into Glaxxes (or beefier units like Gryphons).
Alternately, I kind of want to give [Fire]/Discipline/Truth another try, as I think I’d be able to have more success with it than I did in my early days as a Codex player.
So, that’s 3 builds to choose from, feel free to pick any of them and any deck for yourself.
