Deck's assumptions:

Memefury Shaman mixes Elementals and Overload with some tempo and value plays.

Mulligan

Fire Fly, Prince Keleseth, Bloodsail Corsair, Lightning Bolt (best early value)

Turn 3-4

Annoying Drakkari Defender, huge Flamewreathed Faceless and snowballing Unbound Elemental (propably upgraded by Keleseth and ready to gain Windfury from Windspeaker or Bloodlust buff)

Finally:

With total of 12 overload in the deck possible, your Snowfury Giant gains lower cost, Tol'vir Stoneshaper and Servant of Kalimos can do some value (thanks to these low-cost Giants, Fire Flies and Unbound Elementals), face damaging cards are in your hand, this is your time to strike.

Alternative cards:

You can play this deck without any legendaries but more zoo and aggro cards, or maybe with more control version, with The Lich King, Kalimos, Primal Lord, weapons, portals and Hex or two. In wild version, the best card to choose is Tunnel Trogg and for non-Keleseth version, Lava Shock or Eternal Sentinel.

Have fun, leave +1 if you liked this concept!
