Karn

If I use {karn liberated} +4 and exile a creature, then Karn is destroyed, but I am able to reshuffle Karn into my library, pull him out and use his -14. Do I get the original creature card that was exiled?

Nope. Anytime something changes zones (ie from the Battlefield to the Gy) the game considers it a new object. If Karn leaves play, anything he exiled is gone forever.
