 This is a different view on this archetype. I decided to include some tech cards to my old Highlander deck and right now it is working better. The first one is Mind Control Tech because there are so many other decks that fill the board pretty easy. The second one is Wild Bloodstinger. It is an awesome card that disrupts your opponent plan. Just a quick advise on it - play it on turn 6 only if you have a board to support it because there are situations when you leave big minion on board and you cannot remove it only with the Bloodstinger. Also keep in hand a Springpaw or two for the same very reason when you play the Bloodstinger off curve. I did not included Secretkeeper because it is often easily answered in this meta and for me it does not deserve a card slot in this deck. So far I played quite a lot games with this deck and I shoud say it feels pretty strong. The flexibility that all the discover mechanics give you is awesome. The deck itself has some pretty nice power turns, but because it's a singleton deck sometimes you need some extra value. 

Good luck! :)

Edit: Thanks to @wolpak the deck is  even better now. I removed the Shimmerfly and added a single copy of Secret Plan. 

Edit2: I wanted to try yet another thing with this deck because often I have a big board and no protection at all besides the secrets and Zilliax, so I removed the Unsean Saboteur and adder Conjured Mirage. It turned out that this card works pretty fine in that deck.
