I have a bit of good news for you: your spirit doesn't have a 12 dice pool to resist your binding. The spirit's binding resist should only be twice its force, so in your case a 10 dice pool. So you can re-roll those 10 dice or drop the last 2 (whichever the GM is more comfortable with). Also, with Edge you should be able to spend a point to re-roll your misses (in your case it would be 7).
This was a typo. Accidentally linked Omeed's rolls twice instead of the spirit's opposed roll. I actually did make the spirit's opposed roll with 10 dice, and yes, it actually did get 5 hits. The post is updated with the correct link to Invisible Castle. I really want to spend a point of Edge to re-roll the failures, will do that momentarily.
RE: Magnetbox, I'm playing with him on another forum. He said he'd be on spring break this week with limited computer access. But still, the fact that he did not make mention of that in this thread is probably a bad sign.
EDIT: Edge spent for one extra measly success, but it's cool. It's the principle of the thing! Man, the dice seem to really hate this guy...
DOUBLE EDIT: For the record, the spirit of man's optional power is Fear.
