Seems like a reasonably good duelist to me. Not one of the noobs to fall for my Earthbounds, which has stolen a few souls by now, and knew when to use what card. Just odd that he never used the effect of Prism, to equip it to his Synchro's. Other then that, well done, and Uria Dorm it is.
You'll have to wait for an Amdin to put you in the proper Dorm Group.
