I would also say try Madolche, but right now they can't compete with other decks.
But as Danica says, Fire King, Fire Fist or Inzektors.
I would say that right now, your best bet is probably Inzektors or Fire King.
Reason being, Inzektors are a pretty good archetype that can still abuse Hornet by using cards such as Foolish Burial and Armageddon Knight to get him in grave, and then simply use Centipede, Dragonfly, and Hopper effects to have their devastating effects.
Fire Kings are also a good option because they thrive off of being destroyed, and since Inzektors are still a deck that tops, they can rival the Inzektors in destructive power, or, from what I've seen they can. Not sure what others think.
Fire Fist is still good, but they seem to still be lacking something in the deck that I can't quite put my finger on. Once a few more Fire Fist cards come out (if they do) the deck will probably be capable of being tier 1.
But that's just my two cents.
