Of the 30+ games I played today, around 60% were against Hunters. And guess what? They played DK Rexxar on turn 6 every single time.
Wtf? Hunters are about a 50-50 matchup for Odd Warrior, but playing against a turn 6 DK Rexxar just turns the difficulty level up a notch. It's a miracle I won around 50% of those matchups...
That's the one card that turns the tide in favor of the hunter (for at least spell and minion based hunters). So you go ahead with the assumption that they will hard muligan for rexxar in the matchup against warrior..
