rt，夺冠生物这个异能进堆叠么，如果我有三个具有夺冠生物异能的生物能达成无限进离场吗？

702.72. Champion
702.72. 夺冠
702.72a Champion represents two triggered abilities. “Champion an [object]” means “When this permanent enters the battlefield, sacrifice it unless you exile another [object] you control” and “When this permanent leaves the battlefield, return the exiled card to the battlefield under its owner’s control.”
702.72a 夺冠代表了两个触发式异能。“夺冠[物件]”意指，“当此永久物进入战场时，除非你将另一个由你操控的[物件]放逐，否则牺牲之”以及“当此永久物离开战场时，将所放逐的牌在其拥有者的操控下移回战场。”
702.72b The two abilities represented by champion are linked. See rule 607, “Linked Abilities.”
702.72b 夺冠所代表的两个异能之间有所关联。参见规则607，“关联异能”。
702.72c A permanent is “championed” by another permanent if the latter exiles the former as the direct result of a champion ability.
702.72c 如果一个永久物因夺冠异能造成的直接原因而被另一个永久物放逐，该永久物“被夺冠”。
能达成任意次数的进离场，但是不能无限次平局
如果你只操控这仨生物，那么你可以说一个数，然后在循环这么多次之后牺牲其中一个打破循环
