I heard a theory all the traps guarding the Philosopher's Stone (Sorcerer's Stone if you're a freedom loving patriot. 🇺🇲🦅🇺🇲) were all designed specifically for each member of the trio as a way to improve their knowledge and skills.

But the devil's snare, was that meant for Neville? Dumbledore probably Neville was gonna help out considering the devil's snare is a plant and Neville in his first year, was probably top of his class in herbology.

This was just a theory I seen on a YouTube short.
