I actually kind of liked this show. I was expecting some silly VR card battling with no major consequences like YGO but got real monster battling, destruction, and people dying instead. MC is pretty cool for the most part as well as his angel bitch. None of the characters seem overly annoying yet either. Kind of corny on the story but it can't be helped since it's based on a card game.
i just hope they explain things a little bit more in the next episode, the first one explained nothing about the actual situation of earth
