/**

 * applicable state-based actions as a single event (see rule 704,
 * “State-Based Actions”), then repeats this process until no state-based
 * actions are performed. Then triggered abilities are put on the stack (see
 * rule 603, “Handling Triggered Abilities”). These steps repeat in order
 * until no further state-based actions are performed and no abilities
 * trigger. Then the player who would have received priority does so.
