官方解释1：If you play Outpost during an extra turn, it won't give you another turn，所以额外回合不能使用前哨台。
官方解释2：If you manage to play Outpost twice in one turn, you will still only get one extra turn，所以不论是王座、村庄、石头人还是皇家法庭，一轮用两次前哨只能获得1个额外轮次
官方解释3：If you Throne Room a Treasure Map, with two more Treasure Maps in hand, then the first time Treasure Map resolves you trash it and another one and gain 4 Golds, and the second time it resolves you trash your other Treasure Map but gain nothing (since you didn't actually trash the played Treasure Map that time)，也就是说，如果想获得4金币，那就必须要移除2张藏宝图；8金的话，需要4图
