Vern looked at Smartphone. "Maybe I could. If I had one with me." He answered. "My name is Vern. But you know, following your logic, why would your phone has camera option. It should be just plain 'make and receive calls' thing. And yet, it have other options like sending and receiving text messages, taking photos or playing music." Vern continued, while going in the same direction as Korbin. "Plus right now Duel Disk can be considered as one of practical devices. If we already joined some of them before, why we wouldn't continue to combine them even more? I guess you have a deck. Does it have only monsters in it? Probably not. You most likely combine Monsters, Spells and Traps. But why? You can win by using only monsters. But it's more practical to use them in combination." Vern continued his lecture without enjoyment in his voice. It almost seemed like it's not the first time he tried to explain it to someone.
