Ravensburger treated us to a new card reveal via their social media accounts.
Healing Glow is an Action card that removes 2 damage from a chosen character. This seems to confirm that damage remains on a character after it is dealt. This idea was speculated by many when the box of the gift set seemingly noted that “Damage Counters” were included.
If this is true, it appears that Lorcana is taking the route of Pokemon for its combat system. We will know more for sure when gameplay details are released later this year.
