The passive bonuses on Moon Stone are good. But how to play it?

There are two main ways:

  1. Specific card effects. The best are those printed on investigator cards that you start the game with: Wendy Adams, "Ashcan" Pete and Patrice Hathaway. The best non-investigator way to discard at will (there aren’t many) is Scroll of Prophecies.

  2. Discarding cards due to maximum hand size. Anyone can do this, but it could be difficult if your hand tends to run low. So other than the investigators listed above, Moon Stone would probably only be used by investigators that really want the willpower and agility bonus and have no better or more reliable accessory options.

It's a relic so you can grab it with Elli. The best non-investigator way to discard it at will is probably Cornered, which fortunately is in-faction. — Yenreb · 15
True! I should have said “best level 0 non-investigator” for scroll of Prophecies. — jmmeye3 · 541
Cornered is also pretty good. However i don't think the card is good outside specific combos (bow) and mystics cause the stats don't help win the game, just make the player harder to kill and just slows you down. — Django · 3610
I believe you could also play this off of the discard from Blood Rite. Take extra card draw so that you a) are more likely to draw Occult Lexicon or b) can discard it to hand size as a backup. Might be worth considering in TFA at least — Zinjanthropus · 165
And I think Backpack is, too, a ways to 'cheat' this into play. — Lateralis · 6
Backpack is very clever. I wonder if there'll be a ruling on that. You could also use The Council's Coffer to play it, though there are probably better ways to use that card most of the time. — Zinjanthropus · 165
You could also get it into play with Amnesia. I think you could play it with "You Owe Me One!" because it wouldn't be from "your hand." Would take some group coordination though that might be better expended on a different card. — Zinjanthropus · 165
Dr. Elli Horowitz can get the Moonstone into play without much ado. — dlikos · 20
I don't think backüack works cause Moonstone says it must be discarded from your hand but backpack only says the cards are considered in your hand for the purpose of playing them. So the moment backpack is discarded, moonstone is not in your hand (and not considered to be there either). — Django · 3610

I haven't seen this mentioned much, but Occult Lexicon/Blood-Rite can also discard the Moonstone from your hand, meaning Seekers with Moonstone access, Ursula, Minh, and Rex, have an additional option to get Moonstone out, the main way for Seeker still being Elli. I'd say Ursula benefits the most from this combo. Also, don't underestimate a Seeker's ability to play Moonstone by exceeding max hand size. Card draw is all over the place in the Seeker faction.

Finh and Marie can also play both — Django · 3610

In addition to the ways described above to circumvent Moonstone play restriction, Unearth the Ancients should work. It indeed allows Moonstone to be "put into play", which is different from "play(ed". It may mostly be relevant in a Ursula Downs deck (maybe Minh Thi Phan as well), but still deserved to be mentioned.

Unfortunately, Unearth the Ancients only works on Seeker assets — which is a shame since Moonstone would be quite good in a level zero Ursula if there were an easy way to get it into play. — Spritz · 62
As Spritz mentioned, Unearth and Ancients only works on Seeker assets; however, Archaic Glyphs: Markings of Isis, if you have it, will work. I think it's debatable whether Moonstone is better in Ursula decks than the Tooth of Eztli though, which gives similar boosts (albeit only for treacheries), doesn't have a play restriction, and provides card draw. — iceysnowman · 150
Moon Stone is more useful but harder to play. I use both Moon Stone and Tooth of Eztli and use Dr. Elli Horowitz to search for Moon Stone, if not found I get Tooth of Eztli instead. — AquaDrehz · 165
