121. 指示物（Counters）
121.2. If a permanent has both a +1/+1 counter and a -1/-1 counter on it, N
+1/+1 and N -1/-1 counters are removed from it as a state-based action, where
N is the smaller of the number of +1/+1 and -1/-1 counters on it.See rule 704
所以 +1+1 指示物和 -1/-1 指示物會成對相消，不會共存。
701.23. 增殖（Proliferate）
701.23b. If a permanent or player chosen this way has more than one kind of
counter,the player who is proliferating chooses which kind of counter to add.
某永久物或玩家身負不同類別的指示物時，選擇其中一種來增殖。
