One key difference between this card and the base card that hasn't been touched on...

When the level 0 version leaves play, it takes soothing melodies with it and you can't get them back for the rest of the scenario (removed from game). As such the level 0 version has slot pressure on it for other good Guardian cards.

This text however is absent on this card, meaning once it leaves play your melodies stay, albeit they're the downgraded version of the spell. This removes slot pressure without having to take relic hunter, which further increases the versatility of this card.

Absolutely fantastic card for Carolyn Fern. Carolyn can good value out of even subpar healing cards and loves Hallowed Mirror (0). Hallowed Mirror (3), however, seems custom-designed to annihilate Carolyn's weakness. Rational Thought is a nasty weakness that makes Carolyn useless at her primary purpose. Now, with Hallowed Mirror (3), if we have her signature Hypnotic Therapy in play, we can clear her weakness in 1 single turn by healing a mind-blowing four horror in a single turn. That is just spectacular. It is also fantastic if you are playing with her book strength/weakness. Foolishness is a great asset, but starts with 3 horror that must be healed before he's much use to you. That's one Soothing Melody - one action to get Carolyn her personal Crystalline Elder Sign. It's also great protection for her Black Wind weakness as well, as it makes you a much more reliable horror-healer.

Finally, let's consider that Soothing Melody's effect can be split between investigators/allies. Carolyn can (with hypnotic therapy), split the effect between herself and allies, to heal the team of 4 horror and earn the team 4 resources, all in 1 single round! Better yet, if there is currently only 3 horror out there to be healed, Carolyn can heal 3, earn 3 resources, and then reshuffle the card for later use.

And for one more bonus: this new Hallowed Mirror (3) does not cause Soothing Melodies to leave your deck when it does, so if something destroys the mirror, rest easy knowing your melodies are no longer vulnerable.

The versatility of this new hallowed mirror for Carolyn cannot be overstated and I see it becoming a staple upgrade for Carolyn decks.

Justice for Vincent! The mirror should absolutely be takeable by him. This card is very good but the fact that, of the two dedicated healers in the investigator list, Carolyn and Vincent, only Carolyn can take this card, seems like a pretty significant design oversight. If on Gray's Anatomy, "The card itself does not heal damage/horror..." but is takeable by Carolyn and Vincent, this card should be too. The card itself does not heal damage/horror, but it directly leads to a way to do so.

This is great in a draw heavy Mark Harrington deck. You're able to constantly use your self dmg for +2 ability and continually reap the heal from this. It's built in draw + your ability to to draw in several rounds makes this a priority upgrade for Mark when I play. It might even be the only heal he needs when paired with some soak from allies. I used to spend 5 xp on Spirtual Guidance as an early priority but that xp might be better used on earlier guns now.

Hallowed Mirror (0) is perhaps the best healing option in the game right now, especially for guardians. I take this in most decks that can support it, including as a Dunwich splash. It takes up the accessory slot so there isn’t a lot of competition for it in a primary guardian. The level 0 is a guaranteed two healing for one action with the possibility of four more. But now, HM(3) reshuffles Soothing Melody it into the deck, increasing its consistency. At 3 XP, I think it’s a steal; it could easily have justified 4.

If the Hallowed Mirror is in my play area all the game, after I used soothing melody, do these melodies go into my discard pile? can I use some cards to get soothing melody to my hand and re-usa again? Or after I used soothing melody and they are just out of game
