Sorry for the late reply. I haven’t encountered any others so far, but I doubt I’ve actually fought all of the girls. (There are so many of them!)
Anyway, I’ve spent some time exploring various decks to see what they can do, and while the enemies themselves haven’t been all that interesting, just trying out new card combos has been pretty fun. I see that a lot of people have been singing the praises of the Dark Fairy deck, but that’s really just one of many ways to break the game. Granted, I can kind of understand when it comes to super cards, like Zekari and Belial from the Succubus deck, but some of the run-of-the-mill cards can be insanely strong too. Ultimate Temptations from the Succubus deck, Play Toys from the Galactic Deck, and even Rapid Recovery from the starter deck can give you incredible control over your card flow, especially if you have multiple copies of them.
Perhaps the funniest broken combo I’ve found so far comes from the Zombie deck (which I can only assume people have been overlooking due to the relative lack of voluptuous females). To be specific, there’s one card in particular, Zombie Deathlord, that’s so broken that it can either auto-win the battle or soft lock you. When it’s sent to the discard pile, it automatically sends 3 more cards from your deck straight to the discard pile (and makes you draw 2 Zombies, but that’s less important). Since you can have up to 3 copies of Zombie Deathlord in your deck, the auto-milling effect can trigger the other copies to also auto-mill, and if your number of remaining cards is small enough, that can mean milling through your entire deck… which will make the Zombie Deathlords auto-mill again… and again… and again, in an infinite loop. If you didn’t happen to have a card with a Graveborn damage effect in that loop (such as Zombie Swordmaiden), then the loop will never end, soft locking you. However, if you did include such cards in the loop, then congratulations, you win the battle… eventually. Feel free to go make a sandwich while you wait. Bonus points if you also included Zombie Giantess or Unending Feast in the loop, so you can also gain height as you whittle the enemy down to nothing. Extra bonus points if you included Unending Feast in the loop and spammed Trading Post beforehand to boost the height gains from Unending Feast.
Aside from the balance concerns, I will also say that I wish it were easier to figure out what cards do without having to actually obtain them in battle. A lot of cards summon other cards, but unless you have separate copies of those other cards, you won’t be able to read what they do beforehand. And to make matters worse, a lot of the card explanations don’t fit into the deck builder’s text box, so you don’t even get a full explanation for all the cards that you do have copies of.
Overall, though, I’m surprised at the amount of content the game has, and it’s been a lot of fun, so good job so far. I think I recognized some of the girls from one of your other games, Project F.A.T. Are they all taken from your other games? It’s kind of a neat touch.
