That chapter was good. Dan lost, but then he was dueling Mai and she deserved a win. Liked how you used my card.
One mistake, though. That card Mai used to attack Mid Shield Gardna is not Harpie's Sparrow Formation, it's Harpie's Phoenix Formation. Harpie's Sparrow Formation is a trap that acts sort of like Waboku when there are a couple of harpies on the field.
