Dear lord people are freaking out about this. IT DOES NOT PULL SECRETS FROM YOUR DECK.
Mad scientist did, which is why it was so great for hunter -- the secret got played for free, and it thinned your deck so you didn't topdeck an explosive trap latter on.
With this, the secret has to be in your hand. You can expect one secret, maybe two on a very good day, and quite frequently none at all. Thankfully it's a solid minion on it's own. You know what happens if a hunter plays three cards on turn 3? They end up topdecking by turn five. Especially when full face hunter runs a very early game focused curve.
Mad scientist was the perfect secret-utilizing minion for face hunter. It was played early in the game, put your secrets into play for free from the deck without draining the number of cards in your hand, and curved perfectly into eaglehorn bow.
I can't be seeing this... there must be a mistake because this is the most broken card EVER. This is so insane I don't even know where to start. If anyone thought Secret Paladin was bad they better get mentally prepared for a for a FAR more unforgiving Secret Hunter Yogg deck. My mind is blown right now, what is Blizzard thinking!?
