Thank you, Zephyros! Now I'll expose the extent of my amateurism. I didn't have a reason for the Devil card, except when I was imagining this in my head that was the card that came to mind. I didn't know about its Catalyst effect. Maybe the image of the chains where the Devil is perched on felt to me like it would strengthen the binding spell.
That's alright, I wasn't talking out of any authority. Like others said, your intent was important, and different things work for different people. Some people may use different cards to get the same results.
