Soul-Scar Mage

If a spell or ability an opponent controls causes a source you control to deal noncombat damage to a creature an opponent controls, that damage will be replaced with -1/-1 counters.

If an effect causes a creature you control to fight a creature an opponent controls, the damage is dealt simultaneously. For instance, if your 2/2 creature fights an opponent’s 4/4 creature, your creature will be dealt 4 damage and your opponent’s creature will have two -1/-1 counters put on it.

Soul-Scar Mage’s effect isn’t a prevention effect. Damage that can’t be prevented will be replaced with -1/-1 counters.
