Won't say anything about the size 2 lineup since that's pretty heavily up to personal preference. Size 1's on the other hand, I'd recommend replacing slashknife (you won't be using his effect much in the first place, especially when all your size 2's use gauge already), and Latale Shield Dragon (the 2k power leaves much to be desired) with cards such as Thousand Rapier (which, as Maddog said, is practically staple), Blade Wing Dragon (the move is invaluable when the jackknifes prefer to be on the side), and Double Sword (more high power size 1's always help in clearing the opponent's monsters without having to use Thunderstorm's ability).

Moving onto the spell lineup, it feels like you're worrying a little too much about gauge. I'd recommend replacing Buddy Charge with Dragonic Grimoire if possible. Unlike in other Dragon World decks, Jackknife is able to meet the 5 or less life condition a lot more easily thanks to Thunderstorm.

And this is just my personal opinion, but I feel it'd be better to run only 3 impacts instead of 4. With all the size 2's costing gauge and Braveheart costing 2, you likely won't actually have the gauge to use them that often (I say probably 1 out of every 3-4 games or so), so they'll end up having a tendency to clog up your hand when you want to be drawing other things.

Other than the stuff I mentioned, it's really up to you to test out the deck and see what works best for you.
