During my game 2 I was missing a card in my opening hand and instead it was a blank space in the middle of my hand. On game 3 my shrine to nyx bugged out when trying to play it. It was hard to select in the user interface as it was spazzing out. I eventually was able to play it but the card had a visual glitch where the border of the card looked like the sleave of my opponent's deck. I also noticed in game 3 that my opponent had an unplayable card as he had a gap in his hand like I did on game 2.
