Putting your impressive logic aside for a moment, I'm guessing you didn't mulligan hard for the proper starting cards. This match up is really gimmicky, so it's very important to start off with cards that allow you to exploit the portals.
The ideal first turn is probably playing Voidwalker or Shieldbearer next to the blue portal. He'll have to attack them because of taunt, but he can't kill either on his turn.
Then load up the left side with cheap peon minions in order to prevent Netherspite from getting windfury. After that, wreck his face as quickly as possible. If you take too long, he will play Twisting Nether and wipe your board. Even if that happens, you should have plenty of options to rebuild your board because Warlock has built-in card draw with his hero power. Good luck!!

Crystallizer, flame imp, and kobold librarian are a bit too good. Dead cards without activators, like the eggs, are pretty good.
