1) Is a limited use artifact that spends its final use is immediately discarded?
2) If that final use is negated, would the art would be returned with one use left?
3) (The weird one, which I'd say would never come up except this is Redemption and someone would try it just because) If I use Holy Grail for one conversion, then later it is negated and discarded, and I activate a second HG, which makes a conversion, thus spending the last possible use is it discarded even though it was used only once?

I believe the answers are yes, yes, and "Steve, just shut up already!"
(I want the answer to #1 to be no, but I'm pretty sure it's not)
