Hearthpwn

There are a number of targets for your attention here, but the main cards in the combo are;
Lab Recruiter x2
Myra's Unstable Element
Shadowstep or Cheat Death.
You play Element, then Recruiter something (if it's on the board) and Shadowstep the Recruiter or hope Cheat Death lands on it.
Then you can continually cycle your deck with it.
Good cards to have on the board and shuffle at least once into your deck every now and then;
Augmented Elekk
Elven Minstrel
Vilespine Slayer
For value, the cards you want to be shuffling a lot of are;
Fal'dorei Strider (to land the battlecries more often)
Seaforium Bomber (to kill your opponent more quickly)
For memes, you can shuffle Face Collector into your deck for endless legendaries. Then if you get a good value legendary you can use that as a target. Your win condition evolves depending on what your hand is when you play Element.
