This custom city colored thick durable rubber playmat is a nice upgrade over the standard included paper playmat.  It can be rolled or folded for transport and will lay flat when you arrive to your location.  It is compatible with Clutch 2020 and newer cards.  Do note that the stadium card orientation has changed in Clutch 2020 and thus while it can be used with older cards, the stadium cards will need to be oriented sideways from the design.
