Can I lay down a warrior class enhancement as soon as I lay down my warrior class character from my hand? For instance, I am getting attacked and I have some Babylonians in my territory, but I also have Nergalsharezer in my hand( warrior class Babylonian who says if another Babylonian is in play his O.T. enhancements can't be negated). Also, in my hand I have swift horses( warrior class enhancement that helps me get initiative)so, my question is can I lay these two cards down at the same time and be able to play Head of Gold( Captures up to X humans X being number of Babylonians in play) first with Head of Gold being non negateable?
