With the Buff to Extra Arms, we have a new handy tool for Dragon Soul and cycling with Gadgetzan Auctioneer or a combination of Acolyte of Pain and Wild Pyromancer.  Not to mention that with a Radiant Elemental on board it becomes a 2 mana Blessing of Kings.

Since Nomi Priest already wants to have a lot of spells to cycle, Dragon Soul fits right in.  To help trigger it more reliably, the deck makes use of Banana Buffoon, Shadow Essence, and the aforementioned Extra Arms which are all essentially two spells in one meaning we only need 1 other spell in hand to activate Dragon Soul for a free 5/5 Dragon Spirit.

Arcane Giant and Grave Horror also fit right into the deck and synergize well with Seance.  Even though its mainly there for extra Chef Nomis, don't be afraid to use it as a 2 mana giant or another Radiant Elemental or Gadgetzan Auctioneer if it can really let you pop off.
