This article seems unfinished; there is no Rules or Notes section, and it doesn't explicitly mention which of the rules of orthodox Chess apply, what the depth of the promotion zone is on this extra-deep board, and whether the unorthodox pieces are also available as promotion choice.
As to the initial setup: this would seem more convenient if the Chancellors and Elephants were swapped. As it is, the Elephants compete with the Knights for the same squares during development.
