The objective of this expanded solo variant is to provide a solo play experience that allows the exploration of true multi-sphere combinations and synergies with a single deck.
A short summary: You will create a single deck with 5 heroes (no more than 3 of a single sphere). For most game purposes this single deck will count as two players.
This is version 0.8. I am posting this in hopes of getting some additional playtesting and feedback before finalizing the rules.
