Please make a blue 5* dispeller. Sonja is squishy against red tigers Counter attack

I always go with Wu and 4 of the same colour against Titans.
I have enough 5* heroes. But the game forces me to go with a 4* sonja against a 11* or 12* red tiger, to dispell his counterattack. But sonja is to weak and squishy. Please give us a 5* blue dispeller. Maybe like Sonja, maybe a healer like melendor. But blue and 5* Please.
