CA is correct. King David's ability is no longer active in the discard pile.
HHI isn't in battle, but it stops characters from entering battle.I disagree with Chronic. If the ability was not negated, its still functioning. Only King David gains the benefits of Ignore specific to ignoring characters, but the protection of the battlefield is still active even if David is Discarded.
But isn't KD the only character doing the ignoring? I think if he's out of battle, he's no longer able to Ignore, even though his ability isn't technically negated. I do see your point, jmhartz, about HHI. Pol, how confident are you in your opinion?
