Calvin's is a Magic the Gathering hall located in Bluffington Beach, next to Snoopy's. It is run by Melvin Calvin.
Games begin each afternoon at 5:30pm, and run however long the games take to finish. Multiple games occur simultaneously, with Melvin standing on a chair at the beginning of the afternoon to run through the basic rules for new players.
The amount of cards available for games is limited, with only a few sets that have been collected slowly over time.
