Controls are inconsistent, volatile, and cumbersome. Tooltips you'd get from hovering over key words and phrases on PC only work sometimes. Selecting and confirming versus instantly selecting is implemented seemingly at random. Extreme care is needed to not play a card you just want to preview. Long freezes and times to synch with the server are common. You don't want this on mobile. Wait until you're someplace where you can play this game on a PC where it's excellent across the board.
