If Finder of Paths Unseen moves Heart of the Wildfire's Presence to many different lands, "in the land it goes to" is ambiguous and Wildfire's player chooses which land its "Blazing Presence" special rule applies to. If a since Ravage action adds Blight to two Coastal lands (by cascading), "Runoff and Bilgewater" (The Kingdom of Scotland Level 5) adds a single blight is to that board's Ocean; if the two lands were on different boards, "that board's Ocean" is ambiguous and the players choose which it applies to.
