It's a common occurrence to lose to Ghostal when you're low on PC. 3 Quakes do little against 20 quanta and Discord is doing little damage while Ghostal drops in HP as it would anyway because you don't start the Dim chain early unless you get Hourglasses up early (which is admittedly likely with 4). Once they're up, if you have to choose between destroying Eternity or Dims, you've likely lost.
Would've needed good early damage, Discord, BH and Deflag to win smoothly. That's a lot of pieces. Do note I've seen decks with 4-5 Deflags lose to it as well though. It's not all you need against this classic.
