If Cup of Ace makes me draw the fifth Exodia piece but I cannot draw the second card, do I win or lose?!
You resolve Cup of Ace, draw the final Exodia piece, then cannot draw the second card because your Deck is empty.
You lose. The Exodia win condition is checked after the chain finishes resolving, and you lose by deck out during resolution.
