This is the deck I used to reach 1 rank in legend.
This deck is a modified version of handlock, which uses all the possible tools to finish off your opponent during the mid game. Double combo with arcane golem leeroy jenkins and 2 power overwhlemings and 2 faceless manipulators, 2 soulfire will guarantee you most of the matches a chance to finish off your opponent. They can also be used as removals early in the game or copy big minions with faceless If this deck gets a lot of upvotes I will explain the detail of every single card choice and why some cards aren't included.
