Mulligans
This is first and foremost a tempo deck. Using spells and minions to remove your opponents board while keeping pressure on yours. Use your Brann Bronzebeard, Unearthed Raptor, Sonya Shadowdancer and Carnivorous Cube wisely as these are the cards that will accelerate your jades significantly.
Look for times where you can double trade/ value trade to stay ahead. The weakness of this deck is its low amount of healing. Mistress of Mixtures and Antique Healbot cover that a bit, but you should still be aware of your life total.
