Lets say Luke is attacking an ISD with full shields. Luke gets a crit. Crit goes right through shields, deals face up damage.
Suppose the crit says that the shield zone with the most shields gets reduced to zero.... or pick 2 hull zones and remove a shield from each.
At what point is this not Luke's attack any more? Is Luke's ability still in effect here? Would I effectively have zero shields and fake out that crit?
My gut tells me no. My gut tells me that Luke's ability was only MEANT to apply to getting the damage through, not to circumvent the text of critical effects. But I'm wondering from a rules perspective, if it came up in a tournament, how you'd settle it if someone argued it?
