Extremely good trading potential/board control. Be careful not to overextend. Neo-Gangnam is tech for AA/Sapo which will mostly prevent your opponent to turn the game around. Five Spirit Gate is a flex play, usually you want to burn but if you think the game is going to take some time it can be a great value play. Perfect Grade is not required, add another Blackened Jotun or Terragon for it if you want to.
Also try not to play all your minions every time since this deck is weak to board clears.
