I had never thought about using conceal to hide the Gadgetzan Auctioneer, that's genius.

The Questing Adventurer is really the scary minion in this deck. Where Edwin VanCleef is only buffed by cards played that turn, the Questing Adventurer can continue to grow each turn he is out, quickly become out of control. Also, the mechanic allows you to heal the Questing Adventurer each turn that he is not destroyed.

Would you consider adding Sprint instead of Sinister Strike? My thought process being that you need to end the game quickly due to the fatigue setting and a high number of cards used per turn. If / when you make it to 7 (or 5 with Preparation), it could be a huge advantage to build up your hand for a final combo.

One thought is to replace blessing of wisdom with hammer of wrath. To make blessing of wisdom worthwhile, the minion needs to attack twice (or you just traded a spell for draw one card). With all the low-health minions and no taunt, your opponent will most likely destroy the blessed minion each turn to stop your draws.

I love your synergy of sea giant with murlocs and the paladin power. That is a big bomb that can be dropped early in a match.
