I think this is a reasonable card. With the current SoD at 20hp, I feel like it outclasses Heal, except for the purpose of EM, so now you will get a better heal effect from an in-element card, or using this in light, than you will using this in some other element. And 15/18 hp is still good enough that it can be used in decks like monofire or monoaether like I've seen in the past.
