Once by Gil, who shouldn't even be there, and once by Zouken, who (presumably) used the shadow, which also shouldn't exist. The only time she didn't die to bullshit was the time she almost won.
Even in that case, I still think that I was right. IIRC, in Fate, you die to her twice (or three times) - once attacking her too early, and again when she steals Saber. We both agree that I'm right about UBW, and she dies quickly in HF.
She only dies once in HF, wins twice and loses once in Fate, wins a bunch of times in UBW (and loses once), and loses once in HF, so that means she wins more often than not.
