Interesting desync just happened. Unfortunately I didn't think to take screenshots. There was either a lull in the hordes of PvPers or I got lucky, but I got to play the same opponent twice in a row. The lucky part is my deck totally owns his.
The first game was normal, no desync, I was playing blessed vampires and had 3 of them out at the end. He didn't play any creatures. Second game started normally for me but he asked me why I cheated and had 3 vampires out first turn. Later on the game was classic desync, his messages recycled and his chysaora kept popping in and out of existence, I think it was switching between his old deck and his new deck for me and switching between my old deck and my new deck for him. Thankfully, in both alternate realities, I was winning.
ETA: My deck, if it helps. He had death/water: chysaoras with freeze and plague, a pretty standard poison deck I think.
