Kill your opponent with a 4-Mana 20/20 plus some Fatigue

Step 1:
Create two copies of Coldlight Oracle, that cost one mana each by using regular Coldlight Oracles in combination with Shadowstep, Cheat Death or Shadowcaster.

Step 2:
Draw cards until you hold Hemet, Jungle Hunter and the aforementioned copies of Coldlight Oracle and you are at least on Turn 9.

Step 3:
Drop Hemet, Jungle Hunter. This should reduce your deck size considerably, preferrably down to 5 or less. Pass turn and pray that you survive the next turn. Evasion might help with that.

Step 4:
Play both 1-mana-copies of Coldlight Oracle. Together with your regular draw, it should be enough to deplete your deck entirely.
Now check your opponent's hand size. If they do not have a full hand by now and you can not fill it up by using Preparation and Sap, you are free to concede.
If their hand is full, drop King Togwaggle.

Step 5:
On your next turn, drop The Darkness. As the opponent's deck is empty, this will immediately come to life on their next draw phase.
