Weapon was instrumental: druid 10 mana weapon won me 3 games easily; paladin DR weapon as well. As draw is a big issue for machine-gun priest I went for steal/copy, which was symbiotic with Fingers. Lyra can be replaced, I just play the card cause I love it. And, of course, the Locusts were incredible as well, especially vs Diablos (usually was playable at their weakest, on or around the part III of lock quest).
