This here is an awesome card. Doomed 4 might look unattractive, but the explosive starts you can get from it more than make up for the downside. It's one of the best possible turn 1 plays in most cases, allowing you to get multiple allies/attachments out before the encounter deck has had a chance to do anything. It's quite possible you'll counter some of that threat in the quest phase with your instant army. Legacy of Numenor is especially good against the really brutal fast quests, where you were going to die before 50 threat anyway.

Erestor benefits from this quite a bit, as it's the fastest way to get resources for his huge opening hand. Aragorn is another logical hero, since he can entirely negate the downside. More generally, any deck that wants to go fast can run it, and if you're worried about threating out, just win faster. If you're playing multiplayer and your allies complain, tell them to win faster too.

The best resource acceleration card in the game by a decent stretch if you ask me. Probably one of the top 5 cards in the game as well and certainly my pick for the strongest leadership card. There is no other card providing such a tempo-boost, which gets even stronger in higher player counts. Generally speaking, outside of infinite combo (which most often relies on this card anyways), I have a very hard time thinking about a card that improves your win percentage as much when played in the first round.

One thing I often hear is that players are worried about the initial threat raise. I understand that, however in my experience, the jumpstart Legacy of Númenor provides often saves you 1-2 rounds of encounter cards and passive threat raise, meaning the threat it initially raises is saved later on anyways. This card is insane, there is a reason the game mode in which you star with an extra resource on each hero is called easy mode.

Rating: 10/10
