True enough, you dont know what your opponent will be playing, but regardless, some opening strategies work better against one thing than another. If your deck is capable of starting the match off multiple ways, you will have to make guesses anyway, and it can decide the match whether you picked the right one or not. This is true for even Folrart, and a lot more for Crest where you have even less indicators (lvl, RP, winning streak, forum, chat, observing can all give you hints to use, but not in crest).)
I didnt watch the replays yet, will be back from school in the afternoon, will do it then.
Something must be wrong with me. I'm giving advices to someone i should kill.
