This series had so much potential in the beginning. An atypical MC (A futanari, even) who's half the way to being a villain, an interesting high fantasy setting centered about a magic-like card game with the main characters being equivalent to "Planeswalkers". The summoned creatures were distinct in design and character, the art wasn't bad and the story seemed to have some prospects.
Still, it's been clearly cancelled. Probably because the other work of the authors, a cooking isekai with elves, is still somewhat popular. The first detailed conflict was actually the last, and everything is resolved in a couple of chapters, very rushed. You can still see they have talent, so I expect some decent work from them in the future.
It's a shame, but it's not worth reading in my opinion.
