## Official Rulings
- *(2022-02-18)* Isshin, Two Heavens as One's ability affects only triggered abilities with conditions that are directly related to attacking, such as “whenever [this creature] attacks” or “whenever you attack with one or more creatures.” It does not affect triggered abilities with other trigger conditions, such as “whenever [this creature] becomes tapped.”
- *(2022-02-18)* Isshin's effect doesn't copy the triggered ability; it just causes the ability to trigger twice. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution are also made individually.
