Kind of cookie cutter as far as Unchained decks without Yubel (or non-engine) go. The deck is still pretty strong all things considered HOWEVER since this is a budget variant and I prefer to deck build without non-engine it won't be all that competitive due to instalosing against any established boards that offer up to 2 negates depending on the quality of your starting hand.
The deck (if uninterrupted) can pull off some nutty plays for a few interruptions though and if you have the money (or the card in your collection), then S:P Little Knight will feel right at home in some more optimised variants of the list.
As for non-engine, the Dark Hole Dragon (and the Dark Holes) can easily be replaced and a few Unchained monsters can also be cut to 1 for a more competitive future approach where you actually get to interact with your opponent turn 1. Wailing is another easy to cut spot and the D/D engine can also be cut down a peg if you wish to add a few cards from the Yubel package for an even higher ceiling (but also a higher price...) though if Sharvara ever comes back to more copies we of course will max out on him.
For the main strategy you will usually attempt to combo off to at least end on High King Caesar and/or Unchained Soul of Rage along with at least 1 Unchained Trap set. Rage can then Link off into Knightmare Unicorn (or Little Knight if you have it) for a fun double interruption. And from your second turn on you are off to the races for something bigger.
