Modern is a fast format. By the time your casting cards like
butcher of malakir, most decks will probably have you
dead. I recommend cutting some of the five cmc cards and the seven cmc card.
I would also recommend some more one drops, and look at your curve to make sure you can efficiently use your mana every turn. One last thing is if you can get them lands like
godless shrine and
marsh flats are vary good. Hope this helps.
