Unchained! This deck is fun, though I'm very new to playing it and therefore I can't give a more in depth guide on how the deck works. If you want more lists, this site updated to have OCG decklists and there are a few topping unchained lists here which may give a little more insight on how the deck works! I personally took inspiration from this list here!
In this deck, the main interesting choice here is Tour Guide, this card enables D/D/D Stone King Darius which lets you go into D/D/D Deviser King Deus Machinex with 3 materials, meaning you get 2 activations! Same theory applies for D/D/D Wave High King Caeser using the new level 6 Unchained cards but Caeser is also generically good on its own, negating any activation of an effect which would summon a monster!
Overall, this deck is super fun, popping your own cards for insane advantage! This deck could become meta when DUNE comes out too, its been topping quite a bit in the OCG and they only have 1 Prosperity! Just try not to draw the blue doggy, Coder knows all too well :3
