Magic tables are inserted and deleted table that are temporary objects which is created by the server internally to hold recently inserted values (in the case of insert) and to hold recently deleted values (in the case of delete) to hold before updating values or after updating values in the case of update.
Just imagine if we write a trigger on the table on insert or delete or update. So on insertion of a record into that table, the inserted table will be created automatically by the database, on deletion of record from that table; the deleted table will be created automatically by the database.
These two tables, inserted and deleted, are called magic tables.
