My take on a standard burn deck.
The deck has all the standard burn card.

Searing Blood is a interesting new card. I think that when it is good its great, however, against say mono-b and control it does nothing. I am thinking about running 4 in the side board and removing it from the main board.
I felt the deck lacked power against big creatures with trample or flying and Master of Waves. Due to some of these threats I felt Chained to the Rocks, in the main board, would be a welcome addition.
The deck also needed some way to handle aggro decks like White weenies and rdw. Young Pyromancer is that answer. You can focus on burning your opponent and not have to worry so much about controlling the board. Having a near endless supply of tokens is rather useful. Another consideration for this slot is Satyr Firedancer, however, in a lot of MUs i feel he can be a dead draw.
The sideboard of this deck is focused on becoming a more control type deck. I am unsure about including Chandra, Pyromaster in the main board and, am considering swapping her for Mizzium Mortars.
Revoke Existence seems to be very strong, removing cards that used to be a pain to deal with ie. Thassa, while still doing all the stuff that Wear / Tear could do.
The decks main weakness seems to be a Stormbreath Dragon The two copies of Mizzium Mortars are basically there for that.
Anyway that's about it, all suggestions are welcome.
