玩MA有一段时间了，发现联合牌很强，手上有四张以上就很强了，有点影响游戏的平衡性。
后来找了单机PC版的来玩，发现其对联合牌的单张卖法与常玩的规则不同。
如果单张联合出，第二个出同颜色的不是联合牌的人是获得卖牌的全部收入。
而我们常玩的规则是平分。
究竟为什么这样设计呢？
于是查看了PC版游戏的规则，里面说的是：
If the auctioneer does not play a second painting, the next player in turn
order has the option of playing a second painting, in which case he or
she conducts the entire auction and receives the entirety of the payment.
对此规则的解释是：
The Mayfair version of the game published in the United States
modified the German rules so that when a player completes a double
auction card played by another player, the sale price is divided
between each player who played a card. The original German rules
(which I prefer) have the entirety of the sale price going to the
player who plays the SECOND card. This is the way the rules are
implemented in the game. This does not eliminate any logic to
playing a double auction card by itself; it just makes it a rarer
move. Double auction cards make your hand lucrative but also
make your hand more dangerous by giving you fewer options. This
balances the game.
它说的是原版德国规则是联合收入全归出第二张牌的人，后来在美国修改了玩法。
按原牌规则玩，对联合的使用需要更加合理的策略，同时也更加平衡。
的确，当联合是单张出的时候，如果也能平分收入，那是可以肆无忌惮的出。
同时还可以控制下家出牌，一举多得。这就是大家觉得它强的原因。
如果不能平分收入，那单出联合牌的时候就需要计算联合谁，打压谁，损失这张牌
能够带来多少隐性收益这些问题。
估计是原版的规则让新手感觉“我卖了牌竟然没有收入”，不合理。于是修改成现在
的规则了。但是玩深了的人，对联合牌理解透彻后，会觉得原版规则更加平衡。
