Ward of Lights

You may play Ward of Lights any time you could play an instant. If it was played any time a sorcery couldn't have been played, it gains substance (This doesn't do anything, neat uh ?) until end of turn and when it loses substance (This doesn't do anything, neat uh ?), sacrifice it.
Enchant creature (Target a creature as you play this. This card comes into play attached to that creature.)
As Ward of Lights comes into play, choose a color.
Enchanted creature has protection from the chosen color. This effect doesn't remove Ward of Lights.
