From the campaign:
A pair of rival magicians are teleported to the mystical realm of Fantastiqa, where you will summon fabled beasts and fantastical quests with your shared pack of magical cards. In Fantastiqa: Rival Realms players go head-to-head in an effort to summon regions, explore them, and complete quests.
The campaign is already over its funding goal. So it's on to stretch goals for the next 18 days.
