Can you explain the keywords for me? I'm intrigued by their name, they seem to be fun!
As I understand it....
Legendary represents an additional cost the opponent must pay to discard. So in this case, the Shadow player would have to remove
if they were to somehow discard
Axe of Erebor, Wielded In Rage.
Return is a cost that can be paid to pull a card back from the discard pile. So if
Gimli, Of the Grey Company were in the discard pile (and another copy was not in play, of course), a threat could be added to play him as if from hand.
Desperation text triggers automatically when your draw deck is exhausted. Anvar has many cards that
scour (aka discard cards from the top of your draw deck) to help you intentionally discard large chunks of your deck and trigger
desperation on cards, then he uses
return to pull cards you really need back from the discard pile.
I was skeptical at first--and still am a bit--about the whole thing working, but at least within the framework of this set, I think a player would actually have a decent shot at pulling it off, basically turning their discard pile into their draw deck and allowing them to pull the cards they want from it WHEN they want them. The ONLY problem I see so far is in removing threats, since his cards add a ton of them.
