The Binding of Isaac: Four Souls + +

TBOI: Four Souls + + or TBOI: Four Souls Sherik expansion is a fan expansion made by me. It contains a lot of different series: some of them have more cards than the others, but every single one has at least 4 cards
the expansion is not fully ready: a lot of redacting is still necessary, a lot of cards are yet to be created, a lot of burn-outs are still on the way, and a lot of confusion is still yet to come
English is not my first language and not even a second one, so there will be small mistakes and bad typing, but even with this limitation on my part, every single card is different from others: some less, some more, some are so unique that it's hard to find something even remotely similar, and then there is Forest Bunny, who's complexity is similar to that of the elder gods
Characters are especially interesting: some of them straight up contain a possibility to control the whole flow of the game by themself, some of them require special treatment to master them, and some of them even have an alternative win condition
Also, the balance of the game will be shifted with this expansion: the importance of loot cards is increased to the point, that being forced to play a loot card in an impropriety moment can lead to your demise, and discarding your hand to gain new and unabused hand can be a serious risk by itself. After all, there is no greater enemy to you, than your own greed
But nevertheless, I would like to name a whole list of series, because I forgot to sort cards in decks(it will be done in the future, I hope):

I hope that you will enjoy these cards, and if not, I'm open to critic

P.S. I want to know what was the most complicated and\or confusing card for you so that I could either clarify it or make more cards like that... or both. This will be a never-ending mod and it will be updated unless stated otherwise, so I'm always here to hear feedback and I'm always open (kinda). Anyway, I wish you the best of luck and see you next update (or soon). if there are any questions or if you want to know about new cards, I'm always here -
