Rule 201.4b

If an ability of an object refers to that object by name, and another effect causes a different object to gain that ability, all instances of the first object's name in the gained ability should be treated as the new object's name. Example: Quicksilver Elemental says, in part, "{U}: Quicksilver Elemental gains all activated abilities of target creature until end of turn." If it gains an ability that says "{B}: Regenerate Drudge Skeletons," activating that ability will regenerate Quicksilver Elemental, not the Drudge Skeletons it gained the ability from. Example: Glacial Ray is an instant with "splice onto Arcane" that says "Glacial Ray deals 2 damage to target creature or player." If it's spliced onto a Kodama's Reach, that Kodama's Reach deals 2 damage to the target creature or player.
