Ok I have no idea if this would work so it's a combo / question.
Say I activate Burisl shroud in my artifact pile and Iron Pan on Zek. I then make a rescue (assuming BS is a protect ability) and end then do a large variety of things to deactivate IP. Is my opponent now restricted from attacking me again because BS is no longer being negated.
If this works it think it's pretty awesome. Hope it is legal
