So I completely misremembered and the challenge is a tumblr post.
I know my big issue if I was writing would be the rng aspect of the game, thus the idea of referencing an actual play. I have no idea how much the change of proper rules have completely destroyed the ability for you to echo the original duel, let alone a replication(?) duel. I hope you'll allow yourself forgiveness of a possibly sloppy card play as the more you get through this arc it will only get better (in the meantime, regardless of the card play quality, you have the rest that reads out so well!).
