Ok I'm confused. I have a Built to Last card, it says "Target creature gets +2/+2 until end of turn. If it's and artifact creature it gains indestructible until end of turn."
My opponents tell me that I'm not allowed to use this on my own cards, and I have to use it on my opponent cards, because it doesn't say "in my control." Is this true? My thought was that it could go on any target creature including mine, since there are other cards that say "target creature your opponent controls." Catch my drift?? Help!
