The new support for this deck that got revealed for DUNE is crazy.
The new link makes tour guide a viable option, as well as opening up the deck to be easily splashed in any deck that already runs a bunch of fiends.
The new red soul does everything; it procs the floating effects for all your cards during either turn, and linking it off fetches you a backrow from deck.
The blue soul is also just good extension from grave.
