Great. That makes it a sweet card which can really help with creature control as well. place this on something big like a dragon or something that wont be killed, then use it to cloak key cards like Otys, Fallen elves/druids, parasites, flying weapons, mind flayer etc.
Of course your could play it on something smaller, and just keep it cloaked, but you would still risk the chance or a Rof hitting you if it has 3 or under hp.
Your welcome, glad to give feedback when I can.
fyi I would totally use this card in several decks of mine. Especially my Fallen druid ones which are so much fun.
