FYI: The character names on the cards aren't consistent (some are named Dick Grayson others are named Nightwing Dick Grayson) or is it on purpose?
The cards labeled Dick Grayson are meant to be playable by Dick in any of his personas (Robin, Nightwing, Batman), whereas the ones labeled Nightwing are only playable by Nightwing.
