just play ygopro instead. I mean the android version is just great, with this speed in a year or two ygopro usage will drastically increase due to phone support. tag support, all kinds of formats and cards such as anime, changeable rules for duels etc, AI, AI, effing AI for testing purposes and learning purposes and having fun purposes, automated so that i dont have to know all 6000 cards, i can sit and watch opponent doing some crap in front of my eyes and relax cuz no cheating will happen + i dont have to lift my hand other than say just play i wont chain anything lol.it still might be true that DN is the system still, however DN is built in a different way than ygopro, it haves hard times to keep up with technology and new game stuff while ygopro is growing each day. the only thing that DN has as plus point is play with no download. However download via google play for mobile is just as equal as playing immediately cuz u know, you just click and the phone does the rest until you see icon on your phone that you again click and just play lol.
