This is a lot to take in. Is there a glossary or a wiki or a guide explaining what the mechanics are and what cards do what? Right now I've just been doing trial and error.
A lot of people are new to card game strategy, but the point is to play, be bad, lose and get good. Just like any "competitive" game.
Though this game is single player only.

I can give you a few pointers though.
First, the minimum amount of cards you can have in your deck is 40. There's a reason the minimum is that high. It's because if it was lower, the probability of drawing cards you want is higher.
So the number 1 most important thing is building your deck!
For 99% of strategies you do not want more than the minimum
amount of cards because it means the likelyhood of drawing the card you need is lower.
Second. The more cards are in your hand, the more options you have. Having a lot of cards in your hand is a huge benefit!!!
Cards that help you draw more cards are powerful... to a limit. In Succubus Reborn, Big Breasts, and Lactation help you draw more cards.
Regarding strategies. Succubus Reborn has a lot of them.
Cards have unique properties like Long Handle, Cavalry, Guardian, Ranged and such.
Balancing them is part of the game.
Balancing the amount of squeezers in your deck to build up imagination and guardians to actually defend yourself is also part of the fun.
Plausibly true, but I'm not REALLY here for card game mechanics by themselves.
Have you tried it?
It's like... half the fun for real.
