Cons:

• Some cards that you would want 2, like permanents: Charisma, Another Day, Another Dollar.

Pros:

• Parallel Skids and his 20 card deck.
• Exceptional rogues as mentioned earlier.
• It doesn't limit bound cards (Hallowed Mirror, Occult Lexicon)

Other:

• Interesting that using In the Thick of It+Versatile+Underworld Support nets you 2 traumas and nothing else.
• Rogue - Survivors can start with 15 card in deck, but as all card is limited to 1 instance and 10 are discarded don't know if there is a good combo for this. (Underworld Support+Short Supply)

This card card can cancel Crypt Chill and Corrosion so if you're an asset heavy guardian or survivor, you know how easily these cards ruin your day. Also works for snake bite and grasping hands which are nasty little agility tests that can be pretty cruel.

Does this work with drawing thin? Is this still considered “initiating a skill test”? If so this’ll be even more amazing with Calvin, because then you can just boost the difficulty of the test to draw cards or gain resources, while still knowing that you will win. Additional plus of using this in conjunction with Counterpunch to just annihilate a monster in a single action.

The correct point of comparison comparison for this card is Scavenging (2). It's a card that saves you multiple play actions. Although it doesn't recur from your discard, you're a seeker — you too can do "recursion" it the au naturale way, by simply cycling through your entire deck.

The point of the upgrade isn't to play 2 assets although it's a nice option to have if you have two cheap assets, or you're an Amanda with RGM out. Unlike the 0xp version, this one saves an action because it's also an investigate action, one which you can also manipulate the DC of (Ancient Stone anyone?).

Seekers have no shortage of assets they want to play over and over again. Ancient Stone, The Necronomicon, Mr. "Rook", or the new Eon Chart...some of those are even Relic traited, further increasing efficiency. You can use a charge from your Eon Chart to investigate to play a new Eon Chart as a fast investigate!

Unearth the Ancients is not a simple economy card. You can't expect to throw this into a deck like a Crack the Case or Cryptic Research and have it work — it's acceleration for already powerful decks where you'd play it multiple times over the course of the game. Some of the power Seekers have lost to Taboos, they've regained with Unearth the Ancients, though arguably in a much fairer manner as Unearth the Ancients is susceptible to the dreaded .

I think best use is for a seeker/survivor with scavenging+resourceful (so you can pick back scavenging) and pair this with short supply, and a lot of survivor cards that can be used from discard or gets advantage of discard cards.

I think the biggest problems are the weaknesses. Basically in 15 rounds you go through the same size of your deck with this card as without it (not counting tutoring). You get +15 cards but mill 15 more so it nets 0. So it is nearly the same chance to see your weakness. But if you draw your weakness you have to discard your other card (as you have to discard 1 but you cannot discard weakness) so you lose your chance to choose one. So the main problem is if you draw your "best" card and a weakness at the same time.
