This is the Tyler Gadgetzan Miracle Questing Rogue Deck he was playing at high legend on ladder.
If you’ve not played a miracle questing list before the deck plays out like normal Miracle Rogue with the addition of having a Questing Adventurer on the board to buff as you cycle through your spells. End with a Conceal and you should have 2 or more big minions on board to attack with next turn.
