Valley Hooru (Masters, top 15)

This is a fairly obvious Hooru midrange deck in Expedition, but I think it is well situated. It has most of the best units, it has some Aegis against control, and Lunar Claw can not only kill most 3 and 4 drops, you can also use it to lock out sweepers against control. Most of the cards in this deck need no introduction, but I'd note that Argenport Noble has been particularly good in this meta, especially to kill Nests.

Edit: Somehow, this deck went on an eight game winstreak to make it to Masters at rank 15. I admit, most of the games were very close - but this deck has a lot of air units, and most of the time I am able to fly over the ground units for the win, and my air units often get buffed by the Priestess or Scalesworn Patrol. I think that for some reason, the meta in Expedition has shifted away from the primal Aegis cards, but Plunk and the Serpent are still pretty good.
