For this review I'm going to do my best not to try and see this from the perspective of someone new, since this was clearly Bushi's intent.
Positives:
Animation: This is the best the series has look since V episode 1, and the quality is likely to continue through the series. The short clash between Bastion and Bruce was nothing short of superb.
Fights: They exist.
New Characters: It was very refreshing seeing new faces and not having to drag around over a decade of plot. Megumi and Zakusa were immediately (and subjectively) stand outs I can't wait to see more of, and Tohya really surprised me in a good way, I didn't expect him to be so on edge for a friendly bout.
Negatives
New Characters: On the other hand, some of the characters were immediately 9and still subjectively) really annoying and could drive the series into the ground, like how Tomari continues to narrate the fights and interrupts the main dialogue, or how Yu-Yu is just worse Aichi with a near 1:1 introduction of being bullied then introduced to the game.
No skills: The fact that Tohya got a grade 3 and they made it sound like a bad thing, was very confusing (I know new people don't know the skills) Because I thought that was going to be a really cool comeback, I know it's episode one I just want the show to be a really pretty advertisement I guess.
Controversy: The fact that Vg was trending is big news this might be what takes it from a niche game to third or fourth biggest tcg, there was a lot of spicy debate in the comments, people were overreacting to a lot of things (on both sides), I don't think there was anything to get upset over and I just want new people to see the game for what it is: fun.
Overall for a first episode of a new series this was probably second only to Shinemon, Overall I really think oD has a lot of potential and wil lcapture a new generation of cardfighters.
8/10
