Does the Light Side Heroic Sacrafice card need to have the Dark Side player actually have a ship out with a printed cost of four or lower, to be used (better said, so the Light Side can sacrafice a ship)? Here was the scenario we had today:
Dark Side player had only "Devastator", printed cost of 6, in play (for vehicles). Light Side had "X-Wing Escort in play with text "When this unit leaves play, opponant MUST sacrfice a vehicle unit he controls". Light Side tried to get Dark side to destory "X-Wing Escort" but Dark Side did not. So, Light Side played Heroic Sacrfice" to remove "X-Wing Escort from play, kowing the Dark Side's Devastator would not be affected (nor any other units). Then Light Side used the "X-Wing Escort" text to remove "Devastator".
Since Dark Side didn't have a vehicle of printed cost 4 or lower, can the Light Side still play the sacrafice (even though it does sort of waste the card)?
