[DC] Zatanna Zatara uses magic by speaking English in reverse; what happens if she says something palindromic?
gpt
She has done magic with palindromes as a way to combat someone who was reversing time to thus un-reverse her backwards speech. "Egad! No bondage!" to break free of a trap, "Nurses run!" to conjure a horde of nurses to trample him, and then crushing the villain with "Stack cats!" to create a massive pile of cats on top of him. "Ogre, flog a golfer. GO!" and "Puff up!" finished the job. (She admitted that the Ogre one was really bad.)  


Basically, it's an option she can do, but rarely does because let's be honest, there's not many palindromes that make sense as spells.
