I just feel like cards centred around healing are kinda rampant lately and give a lot of health to themselves or other units (Sharon, Maxi, Robin Tweek, Mr. Slave, Knight Ike to name a few) that make them extremely hard to deal with. So why not have more cards that prevent enemy units from healing? Something along the lines of Power Bind, but they can still use their ability but are inflicted with a status that prevents them from gaining any health back. Just a thought here.
