This review is solely for Jacqueline Fine, as the card is obviously much better than its predecessor for other mystics who cannot afford to lose their spell/relic asset (unless they're running Premonition effects but that's another story).
It gives you the safety of not actually losing your Grotesque Statue or Seal of the Seventh Sign like its cheaper version. But still, when you're playing Jacqueline, you are much more safe in playing Recharge 2 than any other mystic thanks to your own ability, so the only reason you would upgrade this is to get one more measly charge...
Here's where the actual value of the card lies: it is a spell, and with Arcane Research you can upgrade your level 2 into level 4 for free over the course of 2 scenarios. Unless you've built your deck around 7 upgradable spells at the start and have no research to spare.
