I agree that it's an overpowered card in the current meta. Blizzard's thinking is probably they'd rather create cards that combat it directly (better taunts or more secret counters) then just nerf the card. The current problem (and I'm guilty of it too when I play my hunter rush deck) is that by turn 5-6 the game is practically over anyway because if smart your opponent is down to under 10 heath. At that point, the hero power becomes an incredible advantage. My usual finisher at turn six is kill command + hero power = dead or close to it. The fact that owl is a beast and has silence doesn't help matters either. I played a priest last night and he threw the taunt kitchen sink at me at every turn. Actually thought he was going to win because I ran out of cards in hand and he had 4 minions (2 with taunt) on the board (me winning 10-6 at that point). He attacks me with Azure Drake, misdirection goes off, hits him in the face directly. Hero power, gg.
