This deck is built around cards like Prophet Velen, Obsidian Statue, radiant elemental, and spirit of the dead multiple times.
This deck is meant to play spirit of the dead and augmented elekk in order to produce multiple 1-cost copies of Prophet Velen and what comes from Free from Amber.
Free from Amber is meant to produce power cards like The Lich King or Malygos for 100 dust.
Here is the combo:
Throughout the game, play Prophet Velen with Spirit of the Dead and Augmented Elekk. Allow it to die and produce more copies.
Use Séance, Holy Water, and Eternal Servitude whenever you feel like it. These add more cards, usually prophet Velen, to use later.
There are three options: Bwonsamdi, the Dead, Princess Talanji, and Zerek’s cloning gallery
Bwonsamdi will pull all of the 1-cost Velens for the next turn. Play them all and use mind blast and holy smite.
Talanji works with Bwonsamdi by pulling all of the combo cards out in one move.
Zerek’s cloning gallery will put 1/1 copies of all of the Velens. With Spirit of the Dead this adds more 1-drops to your deck.
