Paladin

Paladins are decent Tier 4 which get to gain stats for each kills. Paladins themselves have good HPs. Their damage against Light units are good, but they are poor against Armored units, making them vulnerable. "Divine Will" is really the thing making them dangerous.

Divine Will
Bright light wings will pop out when a Paladin triggers his "Divine Will"

"On each kill, increase 1% damage, decrease 1% damage received, recover 1% HP"

A Paladin can kill many low Tier units to trigger the effect multiple times, effectively boosting himself.
