General changes

Old rule (Core Set - Ninth Edition) New rule (Ravnica: City of Guilds)

Priority

The player who has the option to play a spell or ability at any given time has priority. See rule 408, "Timing of Spells and Abilities." Each time a spell, an ability (other than a mana ability), or combat damage resolves, and at the beginning of most phases and steps, the active player receives priority. After a player plays a spell, ability, or land, or takes a special action, he or she again receives priority. When a player passes, his or her opponent receives priority. If all players pass in succession, the spell, ability, or combat damage on top of the stack resolves or, if the stack is empty, the phase or step ends. Each time a player would get priority, all applicable state-based effects resolve first as a single event (see rule 420). Then, if any new state-based effects have been generated, they resolve as a single event. This process repeats until no more applicable state-based effects are generated. Then triggered abilities are added to the stack (see rule 410). These steps repeat in order until no further state-based effects or triggered abilities are generated.

In the Two-Headed Giant multiplayer variant, teams rather than individual players have priority. See rule 606, "Two-Headed Giant Variant."
