It doesn't have to be a consistent counter since that would just be picking on the cleric because the DM doesn't like one of their abilities, it just has to be an option from time to time. Let the twilight cleric shine in some combats but in others, there will be counters. Every ability has some sort of counter which should be brought out from time to time.
They only real counter is target the cleric deliberately (indicates there's a problem) or use lots of counter spells and dispel magic.
