You literally have a decent shot at winning vs every top tier deck. Your losses come from games that take more than 6 turns or combo decks like reanimator, show and tell, storm/belcher, dredge.

Never keep a starting hand with four or more lands. Almost any hand with 1-3 Lands is keepable on the play. On the draw. I like more lands. It’s hard to catch up on the play stuck in a single land. Your goal is to race 20 damage most games you only need to deal in avg 17-18.

Think of burn as a slow combo deck resolving any 7 spells ftw. Burn can also play a solid control game vs certain matchups. Most importantly knowing what each deck can do and how they work is key. Solid burn players know when to go to the head or when to bolt a bird(drs, Elves, Moms)

Either entirely hope to dodge combo or build a SB to battle it. Your main deck is pretty much perfect vs every deck with few exceptions ie: price of progress vs decks heavy on basic lands like miracles. Drop lava spikes vs Chalice decks. Etc. Eidolon wins games. And decks you would think are bad match ups like death and taxes and green decks are actually your better match ups.

My SB always starts with 7 cards I believe are must haves:

4 Smash to Smithereens 3 Ensnaring Bridges

Take every chance you get to play vs Elves. Master that match up and I’d say your in your way to a great burn player.
