Whoa, weird... This is the second time today that I've been reminded of the Weeping Angels in Doctor Who. Weeping Angels are creatures that turn into stone when someone looks at them, but move incredibly fast when they aren't looked at. And with a touch they can send you decades back in time to live your life and die before you're originally born. The statue-esque image in the card really reminds me of the Weeping Angels...
How about making the regular version a normal statue, and the upgraded version a statue baring teeth and showing fangs? The Weeping Angels are like this: one moment, you're looking at a serene-looking angel statue; you blink once, and the statue is now inches from touching your face, with its hands held out and face twisted to show grotesque fangs.
