Each General can only bid on a maximum of different 18 players.
You mean, each General can be the top bidder on maximum 28 players, right? I mean, if we get outbidded 18 times, then we gotta pay more than we normally would for those players, which is.... not good. Especially considering that other Master could just outbid us forever so we get out of cards -.-.
18.
No General can outbid you forever. Each General gets the top-6 bids he/she made, after which all the other 12 bids
disappear. So if you were at 2nd place, you go to 1st place.
If you pick 18 players, and lose ALL those bids, then yes, you will have zero players, and are forced to buy players for 24 cards each, AFTER the auction has closed.
My tip is: try to pick players that you think you can win.
