In this game HC (that is, me) did a big big mistake in castle age while making too many cavalry archers and camels vs a combination of pikes and knights. Had to move out of my base, big time. But in long one vs one games, the importance of relics, multiple battlegrounds and surprise attacks (in this case with champions, which my opponent kamina could not even think of, as gold was finished long time ago!!) One thing I have learnt from this game is that in early castle cavalry archers are useless units as they are too costly to build, and not worth it early on.
