I dont think quest warlock can work.
Even with all of the tools they added to support discard, without like an actual graveyard or regenerate mechanic it's just not gonna work. Deck size is too small, card advantage too important, the support cards are not powerful enough. It needs like a 7/7 for 7 that summons when you discard it or something, or cards that are immune to discard, or just an actual regenerate mechanic.... otherwise it's just way too random.
