C'mon breh, that's WAY beyond Zatanna's limits.
Her power isn't "anything she says backwards happens". She casts magic spells and saying them backwards just helps her concentrate, she doesn't actually HAVE to do that. There's a limit to what she can do and she's stated that using spells drains her more than people realize.
On topic, most OP characters are easily Flash and Superman. Their writers just get ridiculous sometimes. There was one comic book where a bridge (full of cars and people) collapsed, and when Flash saw it happen he literally went to the library to read up on construction technology so he could learn how to fix it, went to go get some construction materials, then literally went back and reconstructed the bridge as it was collapsing all before anybody actually got hurt. I mean come on.
