The repeatable activation is what separates this from the bluff-and-pray creature-type tricks of its era: it lets you change the host's type as many times as you have mana, at instant speed, in response to whatever the opponent is doing. That timing window is where the card actually lives. A targeted tribal removal spell or a "destroy all Goblins" effect cares about what the creature is at the moment of resolution, and this Aura lets you reset that label after the spell is on the stack; a lord that no longer recognizes its own subjects can likewise be sidestepped by renaming the type. The shapeshifters that ran alongside it could read as whatever type a deck needed; this grafts that same dial onto anything you can enchant. It is a defensive answer to type-based hate dressed as a synergy enabler, and it never settled into either role cleanly. The cost of the design is exactly its open-endedness: granting an arbitrary type does nothing in a deck that does not already care intensely about types, so the card asks for a board where naming "Wall" to dodge a sweep, or naming the right type to feed a lord, is a move worth a mana and an Aura slot. That is a narrow ask, and the tribal designs that could have rewarded it mostly chose cheaper, less fiddly tools.
