Sine the other thread had too many lolz...

What happens if you try to Interrupt Herod's Dungeon with Faith as a Mustard Seed on the character getting captured?

I'd recommend using the cosine of the other thread. You'll probably end up with the correct answer that way.

I think that while you still have the opportunity to interrupt/negate Herod's Dungeon, it's not technically occupied.  So you can't use Faith as a Mustard Seed on it.

I say it doesn't work, as the hero is not technically being held at the site until you pass your initiative to interrupt.

If you had a second hero in battle, then yes you could interrupt it and get your hero back I believe.

Not if I use Burial/SoG on your Thaddeus LOLOLOL then play Murmuring LOLOLOL there goes your offense.

That's quite a point, good sir.

I also agree with Lambo.

I agree with this. Just like playing DoN on Holy Grail during the phase it was used undoes the conversion, interrupting and removing Herod's Dungeon would undo the capture. But I would agree that the captured Hero cannot interrupt Herod's Dungeon to save himself.
