Garth One-Eye hint not working

Tested on most recent commit as I write this (266f5ee3b71f796493b359c6a10b3219dd3b0fc1).

To reproduce: Activate [[Garth One-Eye]]'s ability, choosing a name.

Expected result: The hint lists each card name already chosen.
Actual result: The hint always states that no names have been chosen.

Reproduce the issue at commit 266f5ee3b71f796493b359c6a10b3219dd3b0fc1 by activating Garth One-Eye's ability and choosing names. Start from the implementation of that ability and its hint; done means the hint lists every card name already chosen instead of reporting that none were chosen.
