<P> Sorceries and instants differ only in when they can be cast . Sorceries may only be cast during the player's own main phase, and only when the stack is empty . Instants, on the other hand, can be cast at any time, including during other players' turns and while another spell or ability is waiting to resolve (see timing and the stack). </P> <P> In sets released prior to 1999, a third type of one - shot spell card existed called Interrupts . Interrupts functioned similar to instants but altered how the stack was resolved . Interrupts received an errata which stated that, from that point forward, interrupts were treated exactly the same as instants . </P> <P> The beginning phase is composed of three parts, or "steps". The first thing a player does is untap all cards he or she controls in the "untap step". Then, any abilities that trigger on the "upkeep step" happen . Starting with the player of the current turn . These often include cards that require mana payments every turn . Then the player draws a card in the "draw step". In two - player games, the player who takes the first turn does not draw a card for that turn . </P> <P> No player receives priority during the untap step, meaning that no cards or abilities can be played at that time . During the upkeep and draw steps, however, players can cast instants and activate abilities as normal . </P>
