I was playing against a silver deck in arena and as soon as I played my first turn the cards in his hand all disappeared. He was unable to play any cards because he didn't have any anymore. As soon as another card was drawn, it disappeared as well. Once I beat him, the slots in the special spin were blank, although the spinning animation still played. I also got 1290 electrum from it, instead of the usual 40-150, but I hear this might have been because he was a top 10 arena deck. I wasn't sure whether this was a graphical glitch or an arena glitch, but it appeared to directly affect the cards in his hand instead of just looking like they weren't there, so I think this is a gameplay glitch rather than a graphical one.
