These are the cards you want to be looking for. If you don't have a 2 drop against the other aggro decks, odds are you will lose. Blood to ichor can be a game winning card in your opening hand, but it is most effective while you have another weapon to utulize the extra damage.
This is a pirate dragon warrior list I got from LifeCoach, where I then changed malkorok to ragnaros, and managed to hit legend with it.
