Invert the Skies

Creatures your opponents control lose flying until end of turn if {G} was spent to cast this spell, and creatures you control gain flying until end of turn if {U} was spent to cast this spell. (Do both if {G}{U} was spent.)

Las criaturas que controlan tus oponentes pierden la habilidad de volar hasta el final del turno si se usó {G} para jugar Invertir el cielo, y las criaturas que controlas ganan la habilidad de volar hasta el final del turno si se usó {U} para jugarlo. (Haz ambos si se usó {G}{U}.)
