So uh... Two things.

You really should read Jackknife Gift. I don't know what print run you're reading, but both the wiki and the cards I have say "Choose a monster", so that doesn't let you use Jackknife Braveheart. The wiki doesn't have an errata for it, so it should be ruled as such as well.

Also, about using Jackknife Dragon to call Jackknife "Beistand", thanks! I actually didn't realize it was a free call, I assumed that you had to pay the card's call cost, since it says "call it" and normally cards that call for free say things like "without paying it's call cost". That definitely gives me a better understanding of the deck, I've been using the effect solely to call Jackknife "Burn Energy" just because I don't have any gauge and thought I needed to pay call costs. Beistand may be worth putting back in the deck with this new information, actually, as it's expensive cost was the reason I removed it from the original build.

All in all, I think the gauge building just comes down to personal preference, but the Dragogenius is definitely something I will try out at some point, the deck doesn't have much draw power post-"Gold Ritter", I'll need to do testing though to figure out if I really need it.
