Marjanah is a bad card - unplayably bad - and that's fine within the context of Gateway where the ice is relatively tame and your breaker options are twofold.
There is however one use for Marjanah outside of System Gateway and that's if you're running an AI-only build and expect to see Wraparound but also don't already have an answer in your deck.
So if you're in this one specific situation and you're one influence short for Boomerang, and you really can't afford Gauss or Corroder, then please get in touch; I'd like to hear from you.
In Arabian Nights, I think Marjanah is the daughter-in-law of Ali Baba. Previous cards like Scheherazade and BOOM! are also named from Arabian Nights.
