Bulldozer will be your best friend. Anything that cripples as she get low on HP is almost necessary. CC reduction is also gonna be a big difference. Take out her foxes first enemies second, her healing is very solid so focus on her not the tank.
USE YOUR WALL! It blocks fatal attacks, (Terminus ult, skye ult, ruckus ult, willow seed, BK grumpy, etc...) Most healers need line of sight to heal. block vision from a single target with your wall and burst them down before their healer can react
