Ok, so initial thoughts...
Banefire isn't great here. As a deck, you're not likely to 6 mana in order to trigger what makes it a great damage spell towards players. In that regard, I'd replace it with
Auger Spree if you're using it for creature kill, or
Suffer the Past if going purely for player damage, as the increased utility and instant speed makes it better for that task IMO. Only keep it if you want the choice of player or creature kill, but bear in mind there's better options in those colours IMO individually, but I understand this is a marginal issue.
I'm not a fan of the Bombers unless you can get additional value from them, which you do here, but I still think 4 is too many even then.
Blasting Station is good, but are 3 needed? You'll almost never need more than 1 out. I understand wanting to ensure you draw a sac outlet, but in that case you want more than 3 in the deck. I'd go for 2 Stations and 2-3 of another outlet.
Devouring Swarm is my favourite for aggro, but the Vampire is better for a more midrange approach.
I don't know why you wouldn't use
Rockslide Elementals. To me, they're a cornerstone of any deck like this as they get huge very quickly, and a lot of decks just can't answer them. With sac outlets you can even grow them on demand. I think 3 of are a must.
Quests are good, but not essential. I'd maybe cut down to 2. They're good early, but often dead late. When you have the mana, I'd rather just cast a large creature than hope I can generate one by having to sacrifice my own resources when I may not want to in order to benefit. Warstorm is good too, and obviously works well with the Quests, but I always feel you need to commit to a card or not use it. I would never have a 1 of something like this as it makes its impact too random. Go big or go home!
Thinking outside the box, you could splash a third colour if you wanted to. Jund is the obvious candidate.
Kresh the Bloodbraided and
Sprouting Thrinaxes would be a great addition if going Green, and something I'd strongly consider, as it also allows you to create tokens on demand via
Jade Mage.
Young Wolfs allow a double sacrifice too. Rather than Devouring Swarm as an additional sac outlet,
Thorn-Thrash Viashino would be good.
Doubling Season also has uses, but it less optimal as it only works with half the deck.
