Changing my review to 2 stars. Game needs better optimisation, it burns battery like a hot knife through butter. It heats up everyone of my devices I play on even my Nintendo switch. After last maintenance the lag and unstable server is through the roof n I can't log on. Not enough ways to get gems and if u carefull with your spending can only really get 1 deck to use. Dont even get me started on the 5 min combos I have to sit through every duel. Duels need time limit per turn or max move/turn.
