Ok, first duel with Silent Magician and Restart did the trick, gotta say I was pretty lucky, started with Silent 4 and Lvl Up without having to restart, he managed to sent 2 Servants, but set the King and revived him with his effect, thus removing them. Something really ODD happened: I used Crevice into the D.D. and allowed me to select only LIGHT as Attribute, maybe a Steam vers bug?
