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.
Jenos' Void Grip can detect stealth. Even if the enemy Skye/Strix/Sha Lin Disappears S/he can still be void gripped since its basically auto aim. Use this when they try to disappear and Run away
During Ash's Ultimate ability she is not CC Immune, Makoa can Dredge Anchor her out of her area and Bomb King can stun her with Grumpy Bomb. If she has the Battering Ram legendary she will use this to escape the stun and therefore be out of the area!
If you see Terminus with Seris run for your life because that's a fight you cannot win the best strategy is to either lure seris away from terminus or kill her without terminus even knowing cause he'll try to block all your shots letting her escape
