i dunno if it's been mentioned, but a huge part of this game is completing rows and columns of titles; every row is +1 AP regen, every column is +1 draw per turn. with a thin enough deck (using prayer 1 AP draw 2 and refresh), enough titles, and succubus start, you can beat the final boss with just 25ish lewdness, less if you get lucky
i did a little bit of rerolling for titles and then steamrolled the final boss
arm combo feels a bit weak imo, relies too much on getting the arm rare card to actually pack a punch
leg combo ramps too slow as well, and doesn't even have any big bombs to rely on
"merchant" (i.e. the crunder card and investment) needs in-battle money generation besides levy suite (AKA succubus-ing)
shield is... probably OK? i'd have to try a knight build properly. I believe the high-guard from that 2 AP shield card will block a lot of problematic status stuff...
All in all, succubus start is OP, the others are slightly underpowered afaict
