General changes

Old rule (Masters Edition) New rule (Lorwyn)

408.1b.

Spells and activated abilities are played by players (if they choose) using a system of priority, while other types of abilities and effects are automatically generated by the game rules. Each time a player would get priority, all applicable state-based effects resolve first as a single event (see rule 420, "State-Based Effects"). 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, "Handling Triggered Abilities"). These steps repeat in order until no further state-based effects or triggered abilities are generated. Then the player who would have received priority does so and may play a spell or ability, take a special action (such as playing a land), or pass, as governed by the rules for that phase or step.
