I have to ask what do you think will happen to the artifact when then this saga is over? Do you think it will become a cheevo like the locker keys did, or do you think it will become just a space in our inventories like the one6 key and old fortune city keys? I personally hope it becomes the third cheevo for this saga since every saga I have seen so far (excluding war ones) has at least 3 cheevos and this one would make the third.
When we got to shot the dragon with the turrents in outpost, some pieces of the dragon fell to Delta-V. There might be precious stuff in them which requires it as a key.
It would be nice if all the useless artifacts/mission items would be converted into an achievement. After the event is over, we won't have a need for them. Unless, they intend to add a special turret to Faction HQ that requires this card when they bring back all the turrets. However, it wouldn't make sense as the faction turrets are meant to be used against the opposing alignment.
