Interesting use of this card with parallel Agnes (she can take with parallel card back).
Using her new ability it costs 1 damage but it is shuffled back to her deck. As damage is important resource for her it can worth it.
Netting the use of this card with her ability:
- Costs 1 action.
- Uses 1 card but it is then shuffled back to her deck and a new card is drawn so it nets to no card use.
- No resource cost.
- 1 damage is spent then you can heal 2 damage/horror, netting to healing 1, preferable healing 1 damage
For 1 action getting a damage healed while costing nothing else is a good possibility for her to sustain her ability. (Ofc playing mirror will take 1 action and 2 resources but after that you can play this card indefinitely)
While taking the "normal" back have other possiblities (Like Jessica Hyde or Leather Coat+Scavenging/Scavenging) if someone goes full parallel this can be worthwhile.
As Heirloom of Hyperborea takes the same accessory slot Relic Hunter is desirable, especially that she can draw 2 cards with each use of this card netting for 1 action cost to heal 1 damage and draw 1 card
