Crystal Core Combo Rogue

This Deck aims to accomplish the Rogue Quest and then kill your opponent as fast as possible with different possible combos. The idea is to play Fire Fly and Igneous Elemental  as early as possible to get the 1/2 Elementals. Then you can play 3 of them and get one back with shadowstep. In case your opponent has a big board, you can use Preparation and Vanish to clear the board and get one of your minions back in hand again. To finish the game once the quest is completed, you have several options. The best if you have Finja on the board is to attack with him as a 5/5 to get the 2 murlocs and charge minions for a ton of damage. Or you can play Southsea Deckhand to get Patches the Pirate  for 10 damage or more if you also have a Bluegill Warrior . Finally, you can make a combo with cheap charge minions and Shadowstep and/or Vanish to bring them back and attack again.
