Custom decks
What is a Custom Magic format?
Custom is a catch-all designation for lists that aren't intended to follow the legality rules of another official Magic format. It can accommodate kitchen table formats, unusual deckbuilding restrictions, experimental rules, or just fun lists that don't fit into an established format.
On Archidekt, selecting Custom disables normal format legality checking rather than imposing a standardized ruleset of its own. The actual rules therefore depend entirely on whoever created the format or deck.
