Deck List

After building up the base pieces of the deck over that last 3 months I am finally able to get the rest of the deck. I know that the deck has changed a lot recently and I would like some ideas on how to make mine better before I go and spend the rest for the deck.

To start out, my version of the deck is tweaked specifically for a very burn heavy meta (about 70% of the decks at my local are some form of burn.) The other big tweak that you will see with my deck is that the splash color is black and not the newer blue splash that Jeff Hoogland has put in his version of Chord. I personally like the way that the black splash works more then the blue, but someone could probably convince me otherwise. Another change in the deck is that I only run 2 Nahiri. I would run the whole 4 but I don't really want to add another $40 to the price of the deck. The up side to not running to full 4 Nahiri is that I can make my silver bullet package a little better with two more slots. Many of the cards that I have seen in the deck are in the maybeboard of the decklist and I would like your guys thoughts on how to finish off the deck. The Sideboard and lands also need to be updated because they are based off of an old list.

TLDR: What changes should I make before I buy the last parts of Kiki Chord?
