Only if all four players agree, there is a discard phase (Mus), where they can discard up to all four cards or none at all. The dealer feeds to each player the requested cards one by one. After discard, the players repeat the process of discussing a new discard phase (Mus or not Mus) until at least one of them finally disagrees. If needed, the discarded pile can be reshuffled and dealt again as many times as needed. After a player refuses to have a new discard phase, the playing rounds begin.
