Hydro-Man, Fluid Felon

Whenever you cast a blue spell, if Hydro-Man is a creature, he gets +1/+1 until end of turn.
At the beginning of your end step, untap Hydro-Man. Until your next turn, he becomes a land and gains "{T}: Add {U}." (He's not a creature during that time.)

Siempre que lances un hechizo azul, si Hidroman es una criatura, obtiene +1/+1 hasta el final del turno.
Al comienzo de tu paso final, endereza a Hidroman. Hasta tu próximo turno, se convierte en una tierra y gana "{T}: Agrega {U}". (No es una criatura durante ese periodo de tiempo.)
