When I get to legend (recently with aggro druid) I like to stop competing and have fun. I love nothing more than locking my opponent out of the game and after Mindrender got nerfed, I needed something new.
So I worked out this deck, designed to survive, discount cards and bring out the sword to smash into my opponent's face.
It is suprisingly successful, with something like a 30-40% win rate as of late. Any aggressive deck will tear it apart, but if you can survive to about turn 8, there's a good change of bringing out the sword and smashing face.
The best part is right after you swing with the sword, your opponent will usually play the next turn with 1 mana, and you can tell they think the following turn they will have 2 mana... then you swing a second time and they are either dead or they lose their mana again... then they concede.
In terms of how to play the deck... u gotta figure it out, but I can say that getting full discount from the weapons is critical, as is use of Teron Gorefiend. Finally, hand management is also key as you will often get overloaded and need to drop pieces. Enjoy!
