Since the cards thrown can't be used anymore and all cards
thrown or used are on the table for all to see, i don't feel it
will change anything about the game since the 4 wan originally was
already thrown already.
hmm dkcx u know the game right? when the tiles to be drawn is about
7 1/2, there is this "bao" right, where if u throw out a card that
isnt in the pool, and someone games from that card, u have to pay
for all right?
let's say, if he take 4wan and eat, and by 7 1/2 tiles, there is
no 4wan in the pool, and if u are already listening and u know u
have a chance to zi mo or game, then suddenly u draw a 4wan. 4wan
is not in the pool, therefore most of the time, u will not want to
throw it out and keep it instead to prevent yourself from getting
"bao".
this is where it will change your game, from u listening to
cards, to not being able to game.
