There are two combos in my custom Shaman deck:

• Leeroy Jenkins + 2x Rockbiter Weapon + Windfury+ Flametongue Totem = 28 dmg, 10 mana
• Doomhammer + 2x Rockbiter Weapon = 16 dmg, 7 mana

Rockbiter Weapons and Windfury can be also used on Argent Commander and destroy two powerful enemy's minions, or just kill enemy.

If you haven't got much dust, you can replace Leeroy Jenkins and Doomhammer with 2x Defender of Argus.

You can also put Bloodlust instead something (great combo with totems).

Lightning Storm is a great answer for any rush decks (like Hunter, Zoolock itd.)

Feral Spirit is a very nice spell! You can put Flametongue Totem in the middle of the Feral Spirits. Good to use with healing totem from Thrall's hero power.

Earth Shock is good answer for minions like Leper Gnome, Argent Squire or just silence super buffed enemies.

Instead of Acidic Swamp Ooze you can put other 2 or 3 mana minions, for example Harvest Golem or Faerie Dragon.

Fire Elemental is a nice minion to kill problematic enemy, or just to deal 3 dmg to player. Can be also used in Leeroy Combo, instead of Leeroy, but you must wait 1 turn.

It's my first deck created on HearthPwn, hope you like it ;)
And sorry for my bad english, I'm from Poland and i still learning this language ;P

Edit #1: Replaced 2x Leper Gnomes with 2x Argent Squires.
