Mata Hari is the epitomy of early-game Servant. She is your main debuffer until you get a better one. Unless she is bff or waifu to you, or you are a big fan of bronze-only gameplay, you won't get much use out of her.

The optimal way/time to use her in my opinion is against a male Servant: slap a debuff success rate up CE on her, and pair her with Stheno and Shuten. Very good results (I may try that on the next male boss that isn't a Caster)
