I can see why everyone hates on this card, BUT I can see 1 scenario in which it might be OK. If there is a ton of locations in the staging area and you want to ignore them, then play several of these on a location(or some other threat reducing card) and a Thrór's Keyand TAADAH! That location has no effect on anything. That is the ONLY possible scenario in which this card would be decent.
Power in the Earth
Attach to a location.
Attached location gets -1 .
Gandalf, The Fellowship of the Ring
Core Set #56. Spirit.
Power in the earth is terrible. I know, one for one isn't bad, but odds are, that location isn't going to have one threat; which means you're going to want to travel to it to get it's remaining threat out of the staging area. Even if there was a location with 1 threat, there are just so many better options. At least you've now got a proxy for some card that's actually good.
I can see few special cases where this can be used. For example if you have this 1 locations in staging area which needs 3 progress tokens to be explored. Then yes, you can use power on them and ignore them forever. So from time to time, when I run location scenario and putting deck together I will add pair of those....and then, when I realize I have to much cards in the deck...this goes first off, simply because it's not so important and it can be handled other way. Artwork is fine. Verdict: 2/5.
