Speaking of strategies, any tips on how to win with Sissy? I manage to win pretty consistently with every theme (Bimbo being the most OP imho) except for Sissy.
I won with sissy last night and could probably do it again. Sissy relies on increasing your TF incredibly high to generate large amounts of submission and buy powerful payoffs. Their main mechanic is chastity, where you alternate between locked and unlocked states, and the unique cards in the sissy deck require being in one state or the other in order to function (but are priced cheaper than comparable effects as a result). Some cards have an arrow going from locked to unlocked on them or vice versa, meaning that you need to start in the first state to get value from the card and that it'll change your state once you play it. These effects can be useful if you sequence them properly, as they allow you to switch states to play other cards without needing a chastity card and get additional value while doing so.
I found that skipping the brain stage in favor of getting a good love economy going was most effective, since you want to grab the Sissygasm (permanent +4 max TF if you play it while locked, which is REALLY good) and Anal Training (draw 2 while locked for 3 love) cards as fast as possible. Key control (change your chastity state while drawing a card) is also pretty good, but not required. Later cards make you very effective at generating submission and using submission by upgrading your basic submit cards, doubling submission gain next turn and saving unspent submission, giving you X of all resources where X is the number of times you've changed states this turn (awesome for combo-killing bosses), tutoring out your most powerful submission effects, and converting submission into TF. You should absolutely slot in the special Sissy-theme cards, as these all have payoffs depending on how high your TF is (including one that gives you an EXTRA TURN if your TF is over 100, basically guaranteeing you'll win whatever bossfight you draw it in). Ordinarily, having such high TF is too risky to be worth it, but between repeatedly raising your max TF through Sissygasm and getting the sissy bonus effect (permanent +15 to max TF), you can handle it.
I won by grabbing Cocktease cards to upgrade my love generation (because Suggestive Move is incredibly powerful), then using the built-up love to grab a solid core of card draw and TF boosting effects. It's tempting to want to spend all your resources every turn, but I don't recommend doing this because you'll fill your deck with chastity cards that don't do anything by themselves. Once you can reliably hit 2 chastity cards every turn, lay off buying more.
EDIT: by the way, I love that there's actually a game on here with enough strategic depth that this comment actually was worthwhile.
