Well, as much as this looks nice, there are some things in the card game, that shouldn't happen, because the player ends in an unbeatable and unending game. Like just now i've got 5 image cards in the row at the beginning of the game. I am not able to get any new cards, i can only pass and the oponent does not put any cards on the table, so i can't use my cards. This is very bad mechanic.
You should be able to discard a card in hand, because if both of you got bad cards it again can end up un an unending pass game.
