Encantamiento mundo
Las criaturas no pueden atacar a un jugador a menos que ese jugador haya lanzado un hechizo o haya puesto un permanente que no sea ficha en el campo de batalla durante su último turno.
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.
