 Here's the combo:

You'll need a Counterfeit Coin, Southsea Squidface, Spiritsinger Umbra, Carnivorous Cube and something to reduce the cost of any of these minions by 2 like Cheat Death, Shadowstep or Sonya Shadowdancer.

So basicly you play any of these minions then Shadowstep it or let it die to Cheat Death or Sonya Shadowdancer and you'll have 2 less mana on the combo, then next turn you play spellsinger umbra then southsea squid face, thats 6 mana and it gives 2 dmg on your weapon, then you use your Counterfeit Coin and Carnivorous Cube the Southsea squid and thats more 6 dmg, so you get atleast 8 dmg in your turn then after those 2 Southsea Squidface die you get more 4 and thats a 13 dmg weapon with only 1 combo.
