Isekai as a monster

Make your own adventure. Pick from 47 monstrous transformations cards , 4 summon cards and 25 separate stories cards . As you are walking to work one day. A massive blue magic circle appeared around your feet. Your first thought was. I’ve seen this out of an anime. No way I’m getting isekai summoned to another world as you raise your fist saying I’m going to be a hero. The magic completes, and you are summoned to a Medieval world . You look around expecting a magnificent palace. Instead, you see a monsters layer. You look at a half broken shield on the ground and see the visage of a monster. This is a work in progress. If you see anything like miss spellings, please let me know.
