Z gets no respect, but, IMO, her most powerful spells can take down Thor. He's not unbeatable.,
Mjolnir was designed by a Skyfather, and is one of the most powerful weapons that exist in marvel. It's been shown to affect heralds, other gods, skyfathers, demons, and celestial beings. Show me Zatanna resisting attacks from something on it's level and you might have a point. Loki is an immortal god with magic that's even more powerful than Classic Dr. Strange, and even he couldn't stop Thor from flat out absorbing his life force with the hammer. Zatanna is screwed.
Her "most powerful spells" can get absorbed and manipulated by mjolnir and shot back at her 100x. There's really no way around that. And you still haven't addressed the problem of Thor simply blocking magical forces from the battlefield.
I never said Thor was unbeatable, it just takes more than a strong offense to take him out. I haven't seen any kind of defensive showings from Zatanna that show she can take the kind of punishment that Thor can dish out for any length of time.
She has no superhuman durability and no superhuman speed. That's practically a death sentence against someone like Thor.
