Hi
This is CG (Captain Groleo) where "after an opponent plays or reveals an attachment..."
I'm not 100% sure what that covers ... is that only play as per marshals and reveal when some effect specifically says reveal
e.g. what if someone plays (during challenges) Rhymes with Meek which gets attached as an attachment ... so it meets CG's criteria at the time of the response?
What if someone ambushed in an attachment - that would not be "play" but would it be revealed?
thanks
