MANAHIVE

Equivalent cards to “Master Healer” (white, creature, prevents damage):

• “Aegis of the Gods” (offers hexproof, less direct but protective)
• “Combat Medic” (white, Cleric, can prevent 1 damage to a target)
• “Samite Healer” (white, Cleric, T: Prevent 1 damage)
• “Veteran Bodyguard” (redirects damage to itself to protect others)
• “Master Healer” (the card you requested)

Reason: All these are white Clerics and protect from or prevent damage, like “Master Healer,” but none prevent as much as 4 directly. “Combat Medic” and “Samite Healer” are the closest functional equivalents.
