1) When playing against another player, it looks like Player 1 grabs 1 deck, player 2 grabs 2 decks, and player 1 grabs the last desk. Several NPCs grab 2 decks right away, and then you grab 2 decks. Seems like this should be consistent, thought it may be due to the need to stack the deck for tutorial/novice players.
2) When I want to join a Tales of Tribute game through Group Finder, I find myself accidentally canceling the match. I click "Play Tribute" on group finder screen. I press 'F' to accept the match. Afterwards, I am pressing 'Alt', which I'm intending to use to close the Group Finder screen, but it cancels the Tales of Tribute match and I am penalized for canceling the match, when that was not my intention.
