Everything I was expecting came to me in one peace.
Do beware of the last line of the description: "Classic Spirit Panel Boards - 5 Greyboard Panels, Replace *Existing Cards*". What it means by "existing cards" are the spirit panels which came with your copy of Horizons of Spirit Island, not the unique power cards of said Spirits. So this isn't a loophole to be able to play the Spirits without buying the CHF 40.- game.
