DESCRIPTION
Bruna Rites.
Fill graveyard with enchantments, then hardcast or Unburial Bruna. Drop every single enchantment you can (even on Arbor Elf or Lotleth Troll) as they can all be put back on Bruna wherever they are. an Arbor Elf with a stacked Ethereal Armor and Gift of Orzhov is nasty even.
Use Alchemists Refuge or a flash-backed Unburial Rites to launch a surprise Bruna blocker, enabling you to add all your enchantments to her right then and there.
Once you drop Bruna, the game usually ends, as she will likely be a 15 15, lifelink, hexproof, unblockable monstrosity. Her vigilance is just icing on the cake.
Still unsure of the sideboard, and all suggestions are welcome.
