Our team is currently reviewing current in game skills for updates.
Currently we are aware of a heal-all display bug which can cause cards to appear as if they haven't healed (even though they have) - this should be resolved in an upcoming update. There is also some confusion about the BGE because of the order in which it applies. We also believe the Bomb animation to be a bit confusing in the way that it triggers.
Keeping the above in mind, we are reviewing the current skills, how they perform in battle, their descriptions, and their animations. Keep an eye out on upcoming updates as we may roll out some changes to skills in the next few weeks.
Thank you for all the feedback and continued support!
