Here are some combo for this card what I think. Note that this card only works with symbol (, , , , , , , ). If you think combos with /, you may consider Sun/Moon of Favor. Additionally, you always trigger the condition of this card by Sun/Moon of Favor.

• General usage

  • return important skill card at failure test, which is exactly same as Try and Try Again
  • return over-commited skill card, especially at .
  • commit if a skill test would be failed by 1~3, which is similar as play Lucky!. Note that you cannot prepair the highest Numeric token such as -4 in normal difficulty, so that this card is less robust than Lucky.
  • commit a skill card at success test to gain bonus of the skill card.

• Card-specific usage (except signature/investigator)

  • commit Beloved for . (but, covanent or sun favor is more good in general)
  • commit Take Heart, Predestined for failure test
  • commit Seal of the Elder Sign to convert failure test into success test (I'm not sure but may work)
  • commit Defiance(2) to ignore symbol. (I'm not sure, but Defiance(2) works, but Defiance(0) doesn't)
  • return Unrelenting, Signum Crucis; both cards are already affected before return.
  • commit Unrelenting to draw 2 cards, avoiding token sealing effect.

• Investigator-specific usage
  • Stella: commit Neither Rain nor Snow at , to avoid terrible effect of failure. (encounter test, attack to the enemy engaged with another investigator ...)
  • Minh: commit any skill card at ; then, return just commited skill card by effect.
  • Amanda: return skill card beneath her; then, recycle that skill card for next round.
  • Silas: commit skill card; then, return just commited skill card by his ability. Definance(2) may be a good target for this.

I think there are more combo in world, and I'll add if I find more :)

The main problem is that you cannot be sure that an enemy is spawned at your location in mythos phase. If an enemy is not spawned, you have to plan that you don't move one more round, or discard 2 resources and Ambush; both are bad. On the Hunt & Let me handle this! may help this work, but both card don't guarantee that a enemy is always spawned.

However, it is another source of damage in mythos phase for Nathaniel. Because Nathaniel has very limited cards which can deal damage in mythos phase, this card always guarantees 3 damages without any loss. The fundamental problem can be solved by Gloria. Gloria can look encounter deck. If Gloria looked encounter deck, you can be sure that an enemy must be spawned. Then, it always works! Also, Gloria usually wants to look encounter deck, this has no additional cost like On the Hunt and Let me handle this.

I think Ambush is good card for Nathaniel & Gloria pair. Also, it's good even if only Gloria exists (of Gloria herself).

***this review is rife with spoilers

If you're looking to set up a secret society, you need a few things. First, an evil mastermind to head things up. Then, a millionaire convert to bankroll the enterprise. Also, plenty of slavish zealots willing to die for the cause. And last and most certainly least, the resident dufus, the Pinky to your Brain, the bumbling fool whose enthusiasm for the cause is a perpetual embarrassment to you, who coughs up your most carefully guarded secrets and farts during your most sinister rituals. You try to keep him out of the way by giving him a menial job in the catacombs, but you know he's always there, the weak link, ready to bring your whole organization down.

Behold, the Pinky of the Silver Twilight Lodge. I love him. If you manage this chucklehead right, he'll fetch you two, maybe even three of the keys you need. That's because every time he spawns, he has a new key on him! And fortunately for you, there are ways to keep him coming back again and again and again.

1) Once per game, you can be guaranteed to find Igor (he seems like an Igor) patrolling the Holding Cells. You know this is actually just where the Lodge keeps spare robes and incense, but to keep this dumbass out of the way, they told him the rooms are full of horrible monsters, and that it's up to him to make sure they don't get out! At any rate, my first order of business in any playthrough is to grab the Cellar key and head down to the Holding Cell in order to find out what super important Lodge artifact Igor has accidentally stumbled across.

2) The encounter deck has several cards that may let you recur Igor -- two copies of Mysterious Chanting and two copies of Call to Order. It's hit or miss, but if you have a choice, I recommend pulling him. Of the two, Call to Order is more reliable -- just make sure Igor is the only cultist you're knocking off. Then, enjoy the ensuing farce: Carl Sanford: "Gather, my brethren, as we usher in the new order, as we shed the limits of our primitive humanity and embrace godhood!" Igor, panting and sweaty: "Here I am boss." Carl: "Godammit..."

3) There are player cards that can keep Igor in circulation as well. Persuasion is a good one: it clears Igor's doom, snags his key, and shuffles him back in the deck all for one action -- but you do have to pass an 5 test. My favorite, though, is Dumb Luck. This card let's you filch one key off Igor, and then bring him back the very next turn with a new one. "Meddling wascals -- you took my key of bone! I was going to tell you about the onyx coin in my pocket but now I won't..."

In short, if you've been desperately racing the doom clock in most of your playthroughs, trekking up to the Vault and down to the Inner Sanctum in search of keys, consider an Igor run instead. And then go here to see his modern reincarnation: www.youtube.com

"Ashcan" Pete enjoys having this card immensely. It doesn't reduce his intellect at all, and his willpower stat is purely defensive so he doesn't much mind that getting nerfed, either. Meanwhile, the boost to combat allows him to save Duke actions purely for investigating while Ashcan wields either a weapon or makes use of cards like Brute Force and One-Two Punch to murder enemies with his bare (or bear) hands

Taking 1 damage is pretty harsh, but honestly I've seen other weaknesses that don't even have the upside of dealing 0 damage under certain conditions.

Seriously there are two approaches to this card A: play a big hand deck, well just throw in a body Armour, if you don't have enough cards in hand to have drawn body armor you have less need for it.

OR my personal choice

B: play Harvey as a hyper committing engine, you draw fast, play and commit fast and end up treating this card as occasionally blank which is hilarious, even if you float at five cards for higher education you only take 1 damage from this "instant death" card. I've played Harvey this way and only had a single magnifying glass in play and just picked up every clue in play without ever stopping to to refresh, not having to ever take a draw or resource action and only having about 3 play actions in your whole deck leads to some crazy speed. (once you lose the move actions you begin to laugh like a bond villain)
