I don ' t know about this one . Obviously it goes into Millstyle decks , but Goblin Sapper and Clockwork Giant were both big piles of stats for those types of decks that never saw play . Mill decks really aren ' t trying to win the board , and this card falls into that category . That being said , the card isn ' t bad . It ' s basically a 4 mana 44 for arena purposes and gains 11 over time , and can counterplay some draw cards . If this card sees play anywhere , I anticipate it would be in some kind of MillFatigue Druid build , probably in Wild . With Jade Idol acting as its own Fatigue win condition , the deck could probably afford to play more for the board , and this card is better than the Giant or Sapper . That ' s probably it though .
