GOTM is a set 17 card. I wouldn't hold any wording in sets 17, 18, or 19 as indicative of any intentional ruling or design, as those sets were designed and developed by a single dude in a basement as the whole enterprise collapsed around his ears. Loads of established verbiage were missed or ignored, but this should be taken as the cut corners it was rather than a well-thought-out intentional design. I would point out for instance the difference between the incredibly redundantly worded
Erkenbrand's Horn vs the
PC's errata'd version; the errata added only 1 word but removed a half dozen that didn't do anything. "Reshuffle your deck" is a holdover from SWCCG which always tells the player when to do that, for example; the dude was clearly getting crossed wires.
Durin's Bane is the example I would look to. In spite of the redundant "while you can spot the balrog" portion, it still has a continuous effect. You can also look to cards like
Guma, where there is a continuous effect that requires a particular condition (it just happens to be restricted to a card with a particular title instead of a class of cards).
