376.2.c.1. If a Game Object with a Triggered Ability that is active in a specific zone, it is evaluated and subsequently triggered if it enters that zone at the same time that its Trigger ’s condition is met. Example: Immortal Phoenix says “When you kill a unit with a spell, you may pay [1][C] to play me from your trash.” This ability triggers if Immortal Phoenix is in your trash immediately after you kill a unit with a spell, even if the unit you killed with a spell was that Immortal Phoenix.

376.2.c.2. A Game Object will not be able to successfully be able to evaluate its Trigger Condition , however, if it leaves the zone that its Trigger is active from at the same time that its Trigger is satisfied. Example: Viktor, Leader says “When another non-Recruit unit you control dies, play a 1 [M] Recruit unit token into your base.” This ability triggers if Viktor is on the board immediately after another non-Recruit unit you control dies. It does not trigger if Viktor and another non-Recruit unit you control die during the same game action (for instance, if they are both killed in the same Cleanup due to the damage dealt by Unchecked Power).
