ワールド・エンチャント
クリーチャーは、直前の自分のターンに呪文を唱えてもおらずトークンでないパーマネントを戦場に出してもいないプレイヤーを攻撃できない。
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.
