The thing about the Nasuverse and Touhou characters... aside from Saber's big gun being limited by something called 'collateral damage' and 'not vanishing', the other two are an assassin and a mindreader. 'Saber has Excalibur' is not a sufficient argument--nor are the setting details of BlazBlue, since I don't think we're meant to be brute-forcing that setting.
