Wraith & The Giants Solo Play

About Wraith & The Giants, from BoardGameGeek:

Every 23 years since time unknown, giants have risen from the lands beyond, marching towards the village to feed. Your grandmother fought and defeated these monsters while she was alive; the duty had fallen to her upon the death of her grandmother, and so forth back as far as legend records. Your grandmother is gone, so you now must take up her sword and bow as a living shadow. Can you continue the story and protect the village from a catastrophic end? Wraith & The Giants is a solitaire game of epic battles against elemental giants. Progress through four unique boss fights at three different wraith ages. Chain your card combos to scar and defeat the giants. -description from the publisher
