Weird theoretical situation. IG-88A and IG-88B at PS8 both shoot at PS8 Wes. Aggressors shoot first. B shoots and does enough damage to kill Wes, but Wes stays on the board to get his simultaneous shot. A then shoots at Wes, because it's his only shot, and adds more damage cards to him. After Wes is removed from th board, which of the IGs use A's ability? Is it the IG players choice? Can they both recover a shield, they both did damage the destroys him?
I'd say that only the first aggressor that does enough damage to Wes can use A's ability. What's the correct interaction in this situation? I haven't seen anything like this in real life, but if I do, I'd like to know what the community thinks is correct.
