Ah man. Exclusivity. if you know me, excluding anyone is repulsive. But the reality of being an independent artist means everything I make has a limited availability.
The ONLY exclusive I am producing during this campaign is a Relic Card. The game mechanics for Relics means you will never gain an unfair advantage by owning or not owning one of these cards. Relics are shared between all players in a campaign, and everyone will have equal access to the powerful magic item.
