Stall, stall, stall, stall, draw combo pieces, let them think you can't do anything (or are stupid), play Near-Death Experience and Angel's Grace when you would have died, win the game. Vedalken Orrery is good both for making your sorcery-speed removal better and for casting NDE at the end of their turn.A very cheeky win indeed.
Board in in those
Rebuff the Wicked
-s and
Faith's Shield
-s for game 2 when they inevitably board in enchantment/artifact hate, and then you begin the mindgames - the only reasonable plan your foe might have for stopping your plan, assuming they aren't playing blue, is to use one of the many destroy target enchantment effects to remove your Near-Death Experience. Of course, while they are smugly preparing for this move you can be safe in your knowledge that you can just
Rebuff the Wicked
or
Faith's Shield
their enchantment hate and win anyways.
Use
Immolating Souleater
to lower your own life if your opponent won't kill you.
We pretty much just scoop to infect.
If you can afford it run Ghostly Prison because it's great. If you have some Path to Exiles lying around play them too, they're literally perfect for this deck but I'm poor.
Other sideboard stuff:
Hallow
for burn, Timely Reinforcements for burn or really fast decks, Rest in Peace for anything that uses its graveyard, Austere Command for anything that relies on an artifact or enchantment. Your sideboard mileage may vary - just make sure to have Enchantment-Hate-Hate.
