Poison can kill pretty quick, you don't need a deck that big. You need more creature control, perhaps congeals, reverse times.... otyugh with heavy armor could work well, it is perhaps the most effective creature killer. I'm skeptical about the usefullness of the morning stars, because a bonewall will easily hold back 1 morning star. Use a weapon that has a useful ability (eagle's eye maybe), or titan is 8 unstoppable dmg per round. You may also want protect artifact for that.
