Rule 359.3.f.3
Some information used by triggered abilities is referenced from the trigger condition of the ability. This information is checked when the trigger condition is fulfilled. Example: Lillia, Fae Fawn reads “when I move from a location, play a 3 [M] Sprite token with Temporary there.” If Lillia moves to a battlefield, her triggered ability will be placed on the chain and it will note the location she moved from when it does so. If she moves to a non-board zone in reaction to the triggered ability on the chain, it will not affect where the Sprite token will be played when the triggered ability resolves.
