Okay so there’s only 8 stealth units in this deck, but at least you don’t need to pay any power to trigger them. Frontline Healer and Raniya ultimates conveniently give you health and card advantage. You can trade the lockpicks for your market cards, OR hold on to them for big unblockable attacks with Dreamsnatcher (your most frequent win condition).
There is an abundance of card draw here, so don’t play more than 2 Merriest Mandrakes and/or Beckoning Lumen at a time.
Feel free to add more stealth ultimate cards. I might experiment with Last Carnosaur and Azindel Mastermind, but this deck is generally on the low mana side of the curve.
