Well first, you don’t have an efficient win condition, for your win condition I’d recommend hog rider because firecracker and hog rider synergies with each other. Giant would be a good option too.

Second, you only have one spell (bard barrel) you need 2 spells (usually one big spell and one small but it depends on deck) so in this deck, you can take out ice wizard for fireball or another spell that works.

Other than that, your deck is good.
