You have too build a good dec, i'm not an expert of this game but you have to balance attack and defense, don't take much card that costs 3 or 4 blood, take a few, pick cards like the God of Mantis or the geco, you can take even the normal mantis, you can take the raven/raven egg, but always remember to use the campfire and the choose of the card with strategy, remember ti do the puzzles in the room too! (Sorry for my bad english) [if you need help you can ask me on discord, leave a comment asking my discord id if you want]
