Asper is a member of the Dominion Strategy forum, and can be considered one of the most active fan card creators it had. One of his better known works is the Seasons expansion, which he created together with another user, C0okieL0rd.
In 2020, he removed most of his card images from the forum, leaving the text only versions. They can be read in his thread: Asper's Cards.
