Our Process
Our Process
We print our playtest cards through MakePlayingCards.com using S30 smooth-finish card stock with a blue core designed to reduce show-through. The smooth, varnished surface supports comfortable shuffling, sleeving, and tabletop play.
Tournament Play
Tournament Play
Our cards are often allowed at non-WotC-sanctioned tournaments and casual events, but acceptance varies by playgroup and event organizer. Confirm permission before purchasing for an event. These cards are not valid in official Wizards of the Coast-sanctioned play.
