...that Impfinity and Grass Knuckles are the only heroes that cannot heal themselves, excluding special gimmicks like random card drawing in "Peel That Orange!"?

Reason:
 * Plants:
 * Solar: The only class with healing cards
 * Kabloom: Petal-Morphosis
 * Smarty: Mayflower
 * Zombies:
 * Beastly: Nibble, Nurse Gargantuar
 * Hearty: Medic, Heroic Health
 * Brainy: Mad Chemist, Portal Technician (there's also Eureka)
