I would remove goblin guide, vinelasher and 2 lands to add street wraith, mishra's bauble and 2 shard volley. Sideboard: rain of gore, rakdos charm, thoughseize and death's shadow
I think you should play 4 ragavan, 4 soul scar mage, 4 swiftspear, 1 grim lavamancer, 4 mishras bauble, also Lurrus as a commander. and play more of a b/r prowess list. I would cut goblin guide and iridescent vinelasher. I think prowess creatures on board you will do more damage per turn overall. All the one mana burn spells really make prowess better i think. I would keep all the one mana burn spells and just swap in prowess creatures and ragavan for value. I think turn 1 ragavan is better then turn 1 goblin guide as you get mana off it the next turn. And you can mess up the Op draw possibly. Like if you hit a land and they needed the land you hit. Just my thoughts. I also think 3 ragavan, 4 nethergoyf, 4 swiftspear, 4 soulscar mage, baubles, and all burn spells could be good . As nethergoyf can be a 3/4 most games and only costs 1 mana and will be a a mid/late game threat. I think nethergoyf could be good in burn. Similar to wild nacatyl was.
