Ah. I see you added some considerations of mine to your new deck. Let me advise it further. Take out the short sword. You already have fahrenheit. Take out the fire shields as well, you don't really need them for extra control since you have bolts and rage pot and they are quite expensive. That should cut your deck down to a slim and fast 30 card rush deck. Something vs level 4 is harder since half bloods have twice as much health. You'd want to consider a immobow then.
