This is the best online official Yugioh experience I have ever had. I highly recommend downloading... this is where the 2 stars comes in... only on PC. The phone app takes 3 seconds to perform any action due to connectivity issues on mobile. On PC it is a smooth experience as long as you are not facing anyone on mobile. And trust me, you can tell the difference. That is my only complaint and it makes the game so unbearable to duel on mobile that I only open card packs here and play on PC.
