Actually, it will be 102 damage damage from Kaervek - the cost of an X spell on the stack includes the value selected for X. So it will be 100 + 2 for the in Exsanguinate.

And Kaervek's trigger resolves first, likely removing you from the game and stopping Exsanguinate from resolving at all. Unless you have too much life, hexproof, or an opponent who's bad at choosing the best target.

That Elvish Mystic has been looking at me wrong for a while now, it takes 102 damage.
