普世结界
对每位牌手而言,除非该牌手于其上回合中曾施放咒语或将非衍生物的永久物放进战场,否则生物不能攻击该牌手。
Arboria’s effect cares about the actions taken by players, not their results. If a player cast a spell during their last turn but that spell was countered, that player may still be attacked. The same is true if a player put a nontoken permanent onto the battlefield during their last turn, but that permanent left the battlefield before their turn ended.
