So I've heard that Darkglare Warlock, Reno Priest and Secret mage are running rampant on the Wild game mode. So I tried to theorycraft a deck that can hit three birds with one stone, and Shaman happened to be the stone. And there are key cards that help you navigate through each of the big three matchups.

• Spellward Jeweler prevents Reno Priest from damaging your face through their hero power, significantly reducing their combo potential. And if you survive, Reno Jackson will save you.
• Plague of Murlocs shuts down Darkglare Warlock by turning their measly Giants into tiny Murlocs. Even if they play Loatheb, the card will still cost (8) Mana, so you have more than enough likelyhood to play it.
• Eater of Secrets is self-explanatory. It's a tech to Secret Mage.

The rest uses Shudderwock and Spirit of the Frog to provide card draw and stall the game, trying to win with your Shudder bois. [Hearthstone Card (Fist of Ra-den) Not Found] also provides some board presence.
