Hey I'm new here but I wanted to say thanks for this deck. It has allowed me to start getting upgrades at a decent pace. Also, I can confirm that the deck works decently without full upgrades. When I first started using it I only had supernovas, hourglasses, otys, shards, and 2 towers upgraded and managed to win quite a few cards. For anyone trying this deck without all upgrades: I found that you *must* add another pillar (possibly 2) or you will rarely have enough quanta.
One last thing, I have been trying slight variations, replacing the angel (sorry) with other things. Currently I am using a 3rd otyugh for faster control, but before upgrading my towers I was using mind flayer in the slot (for less gravity usage). He works surprisingly well, and was super helpful in my first time killing chaos lord.
Anyway, keep up the good work
