The elastic IT from NUMS is very strong, and very elastic. You can split it safely into about 3 strands, any more and it's too weak.
It's clear in colour, so I paint mine with a black marker.
It's good for hummer card in some ways, but if you hold it spinning in your hands you can't get it to rise because of the elasticity. You can throw it about 6 foot away from you though, and I've never had it snap on me.
Edit: I just noticed that you want it to add to your card routine. While the elastic thread is good, It's not good for things such as a haunted deck effect. The thread usually just stretches instead of moving the required items, so maybe a less elastic thread is what you are looking for.
