[DC] What are the limits to Zatanna's powers? Seems like she can do ANYTHING so long as she says it backwards.

She has the same limits to her powers as any other sorcerer or wizard. Speaking backwards is how she focuses her magic, and she is a very powerful sorceress. She's not omnipotent, but because she knows her limits rarely cast spells that aren't likely to work. 

She can't go "Live lla yortsed!" Or "Htaed lla dne!" She doesn't have that sort of raw power. Anything more powerful than fighting a supervillain for her tends to require more formal rituals that involve other wizards or spell casters.
