做cs61a实验8时，实现一个卡牌游戏，其中一段英文描述没理解什么意思

Question

描述的是一个牌的效果。

Adds the attack and defense of the opponent's card to 
all cards in the player's deck, then removes all cards
in the opponent's deck that share an attack or defense
stat with the opponent's card.

主要是这句话没懂

that share an attack or defense
stat with the opponent's card.

Answer 1

A new challenger has appeared! Implement the effect method for the Professor, who adds the opponent card's attack and defense to all cards in the player's deck and then removes all cards in the opponent's deck that have the same attack or defense as the opponent's card.
就是移除对手牌堆里与对手手牌有相同attack或者相同defense的牌。
