It started as a traditional Donate deck, then was a Lifegain deck, an Enduring Ideal combo deck, Coin Flip, even briefly Goat Tribal, but I always came back to that original design of just giving away bad stuff to my opponents while stealing their good stuff
Then exile all other Nightmare tokens you control
Plus, the design itself is wonderfully executed with tons of unexpected ways to interact, from flickering the Spellbinder, to Drannith Magistrate, to Stonebinders Familiar
The randomness does have some dups but thats just the bet for bulk purchasing at this price level
If you dont have any lifegain resources on the battlefield, use Resplendent Angels mana ability to give all your creatures a buff with lifelink to create that Angel token
Going to six loyalty is somewhat of a protection ability in itself so you have several options when she lands as to keeping her in play and getting value from her
