Lost in the Park Quest Druid is an archetype that caught a lot of players' attention during the reveal season but that quickly faded away from the competitive Standard environment. Duels, on the other hand, may be a place for it to thrive, given that Nature's Gifts is a Dire Shapeshift that trades the Armor gain for extra flexibility. 

Moreover, Continex was able to pick Elixir of Vigor, a Passive Treasure so strong in the right hands that is set to have just 1% chance to appear during the run! Not only it allows you to never run out of cards, but if you're able to include mostly relevant minions in your deck then the discount effect will really make the difference in the long run.
