Zoe is a 1/1 Elusive that "draws" a card if she hits Nexus. She demands an answer or she starts to out value the opponent. In a somewhat aggressive deck, the extra Celestials she can get are quite aggressive for their mana cost as well.
Her level up condition doesn't matter and you don't really make a deck around it. If they used a more than 1 mana card to remove Zoe then she already did her job.
