Not a duo. Animate Weapon is a air card; therefore this belongs in the trio section.
Apart from that, I don't find the concept of the deck different or original. It's a good deck, it works, but I find it rather... bland. Blank? "Meh." Don't know the word. But still, good deck; it works, so no complaints though. I don't see anything to change or add :/ . Slightly prone to RT (4 quints 6 gavels) but I don't think you'll be flying all 6.
Also, I'm pretty sure I've seen a similar deck somewhere, with overdrive instead of unstoppable... hmm.
