Your one and two drops are priority. But you could keep a bow or cloaked huntress if you have a secret already. Quick Shot can be useful to hold onto against Shaman, Zoolock and Priest for those annoying 1 drops like Tunnel Trogg.
I’m thinking that its okay to run 4 secrets with double Cloaked Huntress and Eaglehorn Bow in the deck. Hopefully the free secrets and bounus charges on the bow will swing the tempo in your favor enough to seal an early win.
