Oblivion Orb
Obviously she doesn't need to attack you, and she's AP, so bramble won't work, but she has a lot of sustain. Aside from that, orb feels nice on TK, as a little bit of AP with a lot of health works very well with his passive. I think this is honestly a really good first back choice in this matchup.
Swiftness Boots
Swifties helps to stick on her, and it honestly might be the only chance to do so against her Q W and E.
Hollow Radiance
A little bit of magic resist feels nice against her poke, and aside from that pushing her in feels great. Heartsteel feels great against her too if you can get onto her and she doesn't have a billion health from grasp autos. Building both is probably a good idea.
