Odd Rogue with Valeera the Hollow

Why did I decide to use Valeera the Hollow in odd rogue deck. Using death knight card will replace your hero power with a new one, so you will loose your upgraded hero power. This 2/2 dagger is very good in early game, and I think that in late Valeera the Hollow's hero power will be more effective. Double Lerroy Jenkins or double Cold Blood can do serious damage. Even though you will rarely use this card as it is an aggressive deck, it will increase your win rate against decks like Control Warrior.
