Yu-gi-oh Legacy of the Duelist mathematician released it was dlc! Still misspelt Mathematician in the title as the last two videos did lol. This video I show you where mathematician is and I show case my Shaddoll Deck 2015, I changed the Armageddon Knights for three mathematician and then I dropped the two maxx c for one hound and one falco. Probably will drop hound for Burden of the mighty.
Stellarknight and Monarch DLC has Mathematician in it!
