I think THIS is the right section to post decks to be submitted if you want any advise
Or... we could kindly ask a moderator to move this thread to the right section. No need to discourage the OP.
Anyway... about the deck.
Firstly, I'm not a good deckbuilder. But, I remember having a lot of fun with something similar like this deck years ago. With the help of some decks here in the forum, I've built adrena-staff, fireflies/hope, mito-dragons etc. However, when talking about arena decks, I realize it's a bit difficult to create a good deck around rustler since the AI is going to play it. Also the fact that you have to include 5 copies of rustlers doesn't help either.
Looking at your deck, I think it would be better to just ditch the fireflies with the queens too and change the mark to light. I suggest replacing them with luci-frogs and few pends instead. Apart from that, I would take out few adrens, heals and just 1 graboid. Again, I'm no expert in this; so take my advice with a grain of salt if you will. Below is my suggested deck.

But if you want to stick with the adren'd fireflies concept (I assumed this what you initially want), you definitely need more air quanta. You can try using dragonflies, but that means more weak creatures and I don't think it's a good idea.
I think I may have written too much here, so let me just stop now.
