Hearthpwn

So I've been aggressively trying to win this on my paladin to start with, as I'm most familiar with that class. But I keep consistently losing, sometimes as early as round 3. Only once did i actually get to the last boss, which promptly destroyed me. I've been using the Icy Veins paladin guide (https://www.icy-veins.com/hearthstone/paladin-dungeon-run-class-guide). My biggest issue is that most of the time the treasures available are all sub-par, and if I do get something decent, the card bundles available afterwards aren't really a match for the treasure... trying to build synergy into the deck just keeps failing due to the total RNG involved.

I do think the practice has been good and I feel like I'm learning good lessons about how to build a cohesive deck, when to hold off on playing something until the right moment, and when to just go all in. Im just a bit frustrated that i just keep failing over and over (and getting no permanent cards or gold from that play mode doesn't help me maintain my enthusiam).
