Unnerving Assault

Creatures your opponents control get -1/-0 until end of turn if {U} was spent to cast this spell, and creatures you control get +1/+0 until end of turn if {R} was spent to cast this spell. (Do both if {U}{R} was spent.)

Las criaturas que controlan tus oponentes obtienen -1/-0 hasta el final del turno si se usó {U} para jugar el Asalto desconcertante, y las criaturas que controlas obtienen +1/+0 hasta el final del turno si se usó {R} para jugarlo. (Haz ambos si se usó {U}{R}.)
