After testing for a long time, I came to the conclusion that no additional card to deliver more damage is very useful to this deck. Druidic Bravery is ideal to beat the majority of the decks in Silver, although, just like any other deck, it has its "natural enemies".
Thanks to the SoB it's pretty easy to play quickly the combination of cards that you need (Druidic Staff, Animate Weapon and Epinephrine). It's not a fast deck, though, because of its relatively low damage rate, however it makes up for this lack of killing speed with its great EM wins rate.
