I used to use ever vigilant a lot. Then I realized it was more efficient to include more cards that did whatever ally I was readying did. It's still not bad, especially on Faramir for a monster quest boost or a utility ally, but I wouldn't put in many decks.
Action: Choose and ready 1 ally card.
Gandalf, The Return of the King
Core Set #20. Leadership.
This has to be one of the most underrated cards from the core set.
It is so versatile. If you are using the classic sneak attack & beorn/gandalf combo, I would highly recommend that you throw this in to your deck. Sneak either of them in during combat. With Gandalf, you can defend for 4 , ready using Ever Vigilant and attack back for 4 . With Beorn you can get 2 big attacks out of him before he runs off.
It is also phenomenal with Faramir as his ability isn't restricted to once per phase and so you can add 2 or more to each questing character!
Ever Vigilant is not a bad card and from time to time comes very handy, so when there is still space in my deck, when all must have cards are in, I'll add a pair. The artwork could be less dark, so the drawing could be more visible. Otherwise ok. Verdict: 3/5.
