Review Detail of Riiskynes in Hero of Card (Dxd)

At first I was very excited about the premise since it has a lot of potential, potential that is unfortunately wasted. the MC feels empty, without interesting background or something that is easy to recognize. It can perfectly be replaced by another mc and the story would not lose anything. The card system is interesting and manages well at the beginning (only giving tests and nothing permanent), but the more chapters you advance you lose how interesting it is and should be the "cards". It's good to give it a try but with low expectations.
