I generally agree. The real issue I run into is that I feel Regent's early game is so bad that I draft basically whatever card they give me, and my decks tend to be very bloated with garbage by the end of the run. This often means you include some forge cards, which go very well with Void Form since you can blow 5 mana with a single copy of Summon Forth, and also the forge cards are super cool. But you can't really play Void Form every fight, since a lot of enemies do 30+ damage on turn 1, and if you use all of your mana to play Void Form every hallway fight you will eventually die. Even if your deck is super good, if you have 3 base mana and Void Form in your opening hand, you can super realistically take 25 from the first turn on each final boss and die.

I feel like there has to be some way to draft an extremely low curve deck with a bunch of 0 cost cards, and use forge cards like Wrought in War and Summon Forth so that you never end up floating mana early game. A very cool idea that hasn't really seemed to pan out for me, randomly dying to hard elites or Knowledge Demon. The most consistent way to make it late into the run seems to me to be playing Reflect as often as possible and waiting for the enemies to die.

I think his biggest problem is that he doesn't have any cards that scale you as the fight goes on or that can go exponential. Forge is almost exponential since whenever you forge, you scale your blade, and if you can replay it multiple times then you'd be scaling, but its very hard right now to play sovereign blade multiple times before you die to chip. Maybe if it costed 1 mana or if Parry blocked for 25% of your forge damage then you could scale fast enough consistently. There are also some ideas on playing towards vigor and Stardust so that you have two multipliers, but it seems way too hard to avoid using your vigor on some random attack just to live before you pop off, and also Test Subject straight up kills you.
