Do you really want all decks that don't use maneuver wounding to be unworkable? Or decks that use followers without
Wise Guide? In order to save one card, you're ruining numerous decktypes. Like you said, there are over 3,000 cards. Why sacrifice most of the game's variety for a single card?
I agree that the errata they did was stupid, but surely a sensible erratum (e.g. "Spot an
![Orc [Orc]](https://lotrtcgdb.com/forums/Smileys/classic/orc.png)
minion to make the minion archery total +1 (or +2 if you can spot a follower).") would be better than ruining most decktypes. Besides, what would you do with even worse cards, like
Mordor Fiend (who, IMO, should have just been errata'd to make his phase action a one-time "When you play this minion" action)?
