Rule 438.1.a

The replacing token is treated as the same Game Object as the card or token it replaced for the purposes of Game Effects that target or reference that game object. Example: A player with Green Father as their legend conquers Navori Fighting Pit. They choose to place the Green Father conquer effect on the chain after the Navori Fighting Pit conquer effect. When the Green Father trigger resolves, Navori Fighting Pit is replaced with Brush. Although the Navori Fighting Pit has been replaced, the “here” in its triggered ability still can have its information referenced, because the Brush inherited all statuses and conditions. The unit Navori Fighting Pit’s triggered ability has targeted will still be a legal target on resolution.
