Blood Magic has some cheesy side effects, and with Paladin Immunity (Time Out!) you'll be getting combos non stop. Try to draw as much as possible, and don't mind your health. Going first it's usually a must, since you can be destroyed by those demon hunters on turn one.
Once you got your Stonetusk Boar on game, it's all about buffing it before the rope gets to the end. An alternative is a Southsea Deckhand triggered with Muster for Battle. And if the game goes up to turn 3 for some reason (usually mirror matches). You can try and repeat your combo thanks to Violet Illusionist.
