Here's the text on Amazing Grace:
"Noon Miracle 6, Boot: This blessed gains +1 influence and does not go home booted the next time they refuse a call out. Your other dudes gain +1 influence for the purposes of controlling locations. Your dudes cannot have their influence reduced by opposing abilities."
Does Amazing Grace give your dudes who are played later that same turn +1 influence for controlling locations? Or does it only apply to the dudes you have in play at the time it is used?
