Some notes on stuff I noticed while playing. I don't know if any are new to you, if not then at least it's a reminder:
All Waterbone sigils appear as Kraken waterborne
Headless Horseman cost is still glitched on the card, but can be played with 13 bones like normal
Ouroboros doesn't have buff
Muscle Mage still has Rabbit Hole
Master Bleene still has Fledgling
Necromancer has Dead Hand
There are a lot of missing Act 2 techno cards: Insectodrone, Double Gunner, all conduits besides the Null one, Mox Module
You removed the master gems, but kept Magnus Mox? What?
Speaking of Magnus Mox, it's too strong. You should remove it when you add Mox Module.
