A much, much cheaper alternative to Sign Magick. Not only does it cost one less resource, you also don't have to spend the resources and action playing the spell you just made room for. And because of its reaction ability and the fact that it doesn't provoke AoO, it's effectively fast if you only play it when you need its effect. This is a card that has so much convenience going on that, if this were a competitive game, it would be considered broken. We'll see how it plays out in practice, but it's very appealing for decks that can take it.
Who benefits most? Mystics like Akachi and Agnes, at 5 will, can use it to replace events that allowed them to fight or evade when their spell slots were full. Mystics whose will is closer to their other stats see less of a benefit, but still might like that third-slot versatility. For non-Mystics, who has the will to make it work? Parallel front Daisy with original back can pump her will to awesome proportions, but that fills her hand slots. Carolyn might actually be the non-Mystic who gets the most from it, as she has decent will and generally free hand slots. It allows her to evade cultists and pick off rats which she normally can't do herself, so it's pretty useful for her too.
Very compact card, performing a lot of functions. Interested to see this in action.
