Okay, so first things to drop. Hammer Mace should go, your Monster line-up doesn't need it at all. Dragonic Grimoires clash with Green Dragon Knights, since it'll make it so you rarely get that low in life. Dragonic Charge should also go. These types of cards seem really nice at first, but they are just not worth the -1, and you have other methods of generate gauge. Finally, drop Dragonic Punisher. Dragonic Punisher itself is just bad, and a Jackknife deck does not have the gauge to use Impacts.

As for what to add in, I'd first bump up Braveheart to 4. Regardless of its hefty cost, you're dead in the water without Jackknife, so you need maximum consistency on getting him out. I'd also pump up your Dragon Shield count to 8 (add 2 more Green Dragon Shields), and either add 2 Dragon Breaths or max out on Dragonic Thunder. I'd also add 4 Dragoknuckles to help keep your gauge up and 2 Dragon Crush to deal with any pesky Items or Spells.

Overall, here's what I suggest:

-4 Hammer Mace Dragon

-2 Dragonic Grimoire

-4 Dragonic Charge

-2 Dragonic Punisher

+2 Jackknife Braveheart

+2 Green Dragon Sield

+2 Dragon Breath/Dragonic Thunder

+2 Dragon Crush

+4 Steel Fist, Dragoknuckle

One last tip would be to consider teching in Dragon Knight, El Quixote to help keep your gauge up. If you were to do so, I'd take the Double Sword Dragons out for it.
