I am getting stuck against sleep deck 3rd battle
Show your list of monsters 
Easiest way is to use poison or lots of purify. If you have something with Poison gas, you can poison your own guys and they’ll be immune from sleep. Ideally the 5 star water cobra, but if you’re not that far, try finding a puffoxin 1 star water or Rhynobrute 2 star earth which should have it too.
Good luck! Be sure to hop back on here if you’re still stuck
