So I reached rank 1 legend on the Europe server yesterday (http://imgur.com/kdPdcFG) and wanted to share this decklist, cause a lot of people think that shaman isn't strong in the current meta, which I think is incorrect.
It's pretty standart shaman list, so I'll note the most important cards and why I've included them.
Neptulon is a big threat that also refills your hand and provides huge card advantage. It is very important card in control match-ups, because most decks don't have enough AoE to deal with all your minions and murlocs, that you got from Neptulon.
Antique Healbot really helps in a hunter match-up, also gives more time against other aggresive decks, like zoo or mech mage.
Best match-ups for this deck are: control warrior, handlock, zoo, druid.
Worst match-ups: freeze/control mage, hunter
