I wish to know. My buddy is saying that you can use Blind Obedience in mono-white EDH. From my belief, if the card has a black mana symbol on it, it no longer is legal in a mono-white EDH such as the case with Blind Obedience. So is it legal or is it not?
Though the full Comprehensive Rules entry for Extort does contain a Black mana symbol, having the Extort keyword ability doesn't add that symbol to a card's rules text (and reminder text never counts for color identity). The color identity of Blind Obedience is White.
