Hy guys, first time poster here. I HAD to share this deck with you, since it's doing really well for me at the moment. Only one loss from rank 5 (1 star) to rank 3.
Although the way to play this deck is almost identical to the KFT Tempo Rogue, if this deck gains some upvotes I'm gonna write a more detailed guide.
The corridor creeper is AMAZING: in a board-focused deck such this one, it's not rare to drop him on turn 4 at cost 1/2 or at turn five at cost 0, perhaps comboing him with a Vilespine Slayer. The tempo playing a 5/5, a 3/4, and destroying an enemy minion gives is HUGE.
I'd consider keeping him in the starting hand, if you have a good 1-2-3 curve.
EDIT: Some of you correctly pointed out about How Sonya Shadowdancer is missing. If you have her, feel free to try her instead of one of the Elven Minstrels, and see how it goes. I'd try it myself, but (I'm sure) as many of you I'm gonna save my dust for when it's certain she's going to be meta. So, if you have her, play with her. If you don't, just sub the Elven guy in (at least for now).
