Just playing, I have found that Buccaneer is a 5 star card because most players don't want to waste a removal on a 2/1.  But at the same time, if they don't it's 4 damage on the next turn from your Hero Power.  

I can honestly say that since the nerfs to Preparation and Raiding Party, I didn't think this deck would still function.  But I was proved wrong.  I think the key to my success against Big Priest (specifically calling it out since it is the most prominent deck in Wild) is aggro and leave his minions alone.  But I love hitting a Sap on a big minion they pulled with Barnes.  Anyway, I like it, it plays well.. and it helps get those wins up in Wild.
