Welcome to the Official Redemption® Message Board!
I would like this card better if it said something like this: "If a N.T. angel is in play, search deck for a good dominant and then set Mary aside for X turns." X could equal the number of N.T. females in your holder's territory or something. This way Mary isn't searching for good dominants each turn. That could be OP'd as was stated earlier. I think this might work for your idea a little better. Theologically, I think it's ok as she did give birth to Christ and she could search for SoG. I'm married to a former Catholic. I can appreciate this card as I know that Mary is highly regarded in the Catholic church.
