Highelf support card. "Action: when you play a development from your hand, look at the top card of your deck. You may put it on the top or bottom of your deck."
If I have multiple Barracks in play and play a development, does each one work on the same top card, thus being a waste, or do I look at the top card for one Barracks and then put that card at the bottom of my deck, then use the next Barracks action to look at the new top and so on?
