I think this card is fine particularly with Akachi Onyele in 2-handed solo*.
I dont think your going to use all the charges on this card (1 or 2) will probably do the trick (as that's 3 actions). Its not always helpful but losing a turn (2 or 3 actions) to not lose a gator seems worthwhile in a scenario that is spamming horror.
You dont have to wait until youre on the brink to use the card if you are in a scenario that is pressing a series of horror attacks threatening one of your gators you can be proactive (as you may need to replace the arcane slot later).
Again I particularly like this with Akachi Onyele as you can get one or two uses out of the card and than moves the charges to Angered Spirits or swap the card back out with Spirit-Speaker
I dont think the Arcane slots are that big of an issue as you have 2. Simply replace this with the card you need or replace the Arcane slot thats least helpful/empty with this card late game if you are desperate for healing.
Some cards that work well with this card: Prophetic, Uncage the Soul, Torrent of Power...comboing some of these cards trivializes the downside of the card (2-cost and slotting). If some of those cards are already in your deck this add isnt half bad.
Since this is a level 0 card its an easy replacement later on in the campaign: Earthly Serenity.
note: I am still fairly new to the game and providing the review from the perspective of a primarily 2-handed solo player - so take the review with that in mind.
