Tipps against Holliday

So it seems it's her turn at being "OP" and making me cry and she's especially anoying because I don't find her very interesting to play against.

Until she gets nerved, what can I do? Does defuff reducer work on barrel knockup?

Anything at all I can do against ger ult? (Does etherial shift/debuff remover work against it?)

Any notable items that stop her 3 from blasting through my health in 2 seconds in the early and midgame?

Any tech that works against being barrel-juggled to death?

How am I supposed to play around her bounce pad tactically (besides avoiding the stun)? Mx problem here is that aim is a weakpoint of mine and she might as well have metal skin while she's hopping around.
