Reason: Ok so I found out this too:
 * Plants:
 * Solar: The only class with healing cards
 * Kabloom: Petal-Morphosis, Seedling
 * Smarty: Mayflower
 * Zombies:
 * Beastly: Nibble, Nurse Gargantuar
 * Hearty: Medic, Heroic Health
 * Brainy: Mad Chemist, Portal Technician
 * Sneaky: Tomb Raiser Zombie (spawns a Mad Chemist)

This leaves Grass Knuckles the only hero that cannot heal himself.
