If a gnome casts war spoils before attacking, can the attack-ee then ambush the gnome? If so, does he get 0 acres?
This situation's never come up for me, and I just happened to think of the question as I was looking over our war earlier today.
I would assume that the person who got attacked could no longer ambush if WS had been used but am hoping the Utopian community can answer this question once and for all.
