Simple, Akaik, killing an enemy unit is a +1, inflicting damage is +.5 for each damage, having an attack negated is +1 for each unit involved in the attack, and reducing/recovering damage is the same as inflicting it.

So in order for Cheering Good Luck to turn into a -1 it means you needed to have inflicted no damage with it or its skill, and failed to destroy any monsters using it either.
