This came up in a game today, and I wanted to check on the way I understand the interaction between these two cards:
X-Wing Escort is in play. The DS player has two vehicles, vehicle A and vehicle B. The LS player attempts to play Heroic Sacrifice.
My opponent believes that both of the vehicles are destroyed, claiming he can choose his target for Heroic Sacrifice after X-wing Escort resolves. I explain it in this manner (reference the FAQ):
1) There are no play restrictions; it is an action window and both players have at least one vehicle
2) The cost of the card is determined as 1 - its printed cost
3) No modifiers to the cost
4) The LS player uses 1 Rebel resource
5) The LS player targets his X-wing Escort and vehicle A
6) The effect of his action resolves and he sacrifices his escort and attempts to trigger its interrupt.
At this point I choose vehicle A, the same vehicle he has targeted with Heroic Sacrifice. This causes his Heroic Sacrifice to be cancelled, as there is no longer a valid target.
Did I get this right, or is the second target (the opponent's vehicle) chosen after the sacrifice of the LS vehicle is chosen?
OR
Is the sacrificing of the LS vehicle part of it's cost?
