Another problem with MTG is the rotation format. Cards of every few sets are clustered as a a block. When the block switches, you cannot use any cards from old blocks unless they are being reprinted in the current block. This forces you to buy many new cards regardless of how complete your old deck was. Its something lyk vanguard's G regulation, except this is more of the main format in MTG events and local tournaments.
