Dragon Paladin is so good. Dragon cards have such good value. The only thing is I'm always hesitant to play Hungry Dragon (gives your opponent a 1 mana minion) and he becomes a win-more card. But on the other hand, it gives me a card to keep in hand to act as an activator for Blackwing Technician, Blackwing Corruptor, and Rend. Drakonid Corruptor acts as a pretty good dragon activator too since I'm not normally taking opponents to less than 15 hp until late game / I ultimately win tempo.
Also, Sylvanas => Ysera Awakens is such a great combo. No one ever expects it.
