There are tons of Quest Rogue lists that rotate within the HS community, but this list from Chris "Fenomeno" Tsakopoulos, a pro player from Greece, allowed him to stay in the top 100 legend for weeks after the release of Un’Goro.
The deck has many different outs, the best of which is Glacial Shard. It can be effectively used against aggro decks -- the Achilles’ heel of all Quest Rogues. It can also freeze any early minions on board several times before the Quest is accomplished and give you enough time to turn your 1-health minions into 5/5s.
Bilefin Tidehunter is another interesting inclusion, as it may provide the much-needed Taunt during harder times.
