Legacy

Legacy allows cards from all sets that are legal for constructed play (known as an "Eternal" format). It maintains a ban list based on power level reasons. The format evolved from Type 1.5, which allowed cards from all sets and maintained a banned list corresponding to Vintage: all cards banned or restricted in the old Type 1 were banned in Type 1.5.[14] The modern Legacy format began in 2004, as the DCI separated Legacy's banned list from Vintage and banned many new cards to reduce the power level of the format.[14]

Wizards has supported the format with Grand Prix events[15] and the release of preconstructed Legacy decks on Magic Online in November 2010.[16] The first Legacy Grand Prix was Grand Prix Philadelphia in 2005.[17]
