Ah, but suppose you pull this on a potential meal that knows their Faerie lore...? What if they pretend to fall for it<Aw, cute green horsey!> but just as your about to spring the trap, they flip the script and slip a briddle over your head...? THAT'S what really makes humans dangerous. Not their affinity for cold iron or their frankly terrifying rate of reproduction, but once, just once in a very great while... you run into a smart one!
