Never have I seen a Servant so anti to somebody that their kit is solely focused to dealing more damage to them and only them. Even Penthesilea doesn't go to "I only kill Achilles" extent.

All of her skills involve either hit or being hit to be granted more effects. I noticed that you mean it that the 1st skill's attack up on buff lasts permanently after activation, but once cool down refreshes, can the buff stack? She would work great with a teammate that grants her taunt. I mean, 60% defense up for 3 turns? That puts Imperial Privilege to shame.

I think she works best for longer fights. She comes equipped with sufficient self defense and control that fits her in stall teams. The only problem I think is that she brings only 1 Arts card into the deck, and stall teams generally turn to Arts teams to do so.

Personally, I don't think she fits my playstyle, so I don't think I would use her as much. She seems like she needs the right team to function well, otherwise her skill triggers would be all dependent on RNG. A team with Grendel, Summer BB, and Kiritsugu would work pretty well. High star focus and all good pairs with Grendel. Though that Quick, Arts, Buster NP chain would probably not do too good.
