I've been trying to find a decent
new Oath build for a long time; and after building many variations of Oath I've come to a combo version that I've found works very well a lot of the time.
The idea is to dump your whole library into your graveyard and then Recoup Yawgmoth's Will and go insane. There's only one problem with this - flashbacked Recoup + Yawgmoth's Will =

So, naturally the deck is very mana consuming; but as I am using red and black I have access to many nice rituals.
Yawgmoth's Oath:Mana Base:1 Black Lotus
1 Sol Ring
1 Mana Crypt
1 Mana Vault
1 Lotus Petal
1 Lion's Eye Diamond
5 Moxen
1 Tolarian Academy
4 Forbidden Orchard
2 Tropical Island
1 Volcanic Island
2 Underground Sea
2 Polluted Delta
1 Flooded Strand
Essentials:4 Oath of Druids
1 Obstinate Familiar
1 Yawgmoth's Will
1 Recoup
Acceleration:4 Dark Ritual
4 Rite of Flame
1 Fastbond
Disruption:4 Duress
2 Extirpate
Draw/Tutor:1 Ancestral Recall
1 Necropotence
4 Brainstorm
1 Demonic Tutor
1 Vampiric Tutor
1 Imperial Seal
1 Crop Rotation
Storm Enablers:1 Chain of Vapor
1 Hurkyl's Recall
1 Rebuild
The Kill:1 Tendrils of Agony
Well that's the list. The deck's aim is to drop an Oath as quickly as possible, just ignoring the opponent. You have Duress and Extirpate to ensure your key cards aren't countered, you have the 8 Ritual effects to make sure you can cast Recoup --> Yawg's Will, and you have Obstinate Familiar to stop you decking out once your library is in the 'yard.
So, explanations!
Oath of Druids - I guess this is obvious but I'll explain anyway. You simply use this to tutor up Obstinate Familiar and dump your library into your graveyard.
Obstinate Familiar - Once you have no library you need a way to prevent your draws; while the "Words" enchantments would work as well, they can't be brought into play using Oath, so I chose Obstinate Familiar to ensure I don't deck out.
Recoup - Allows you to play Yawg's Will from the graveyard.
Dark Ritual/Rite of Flame - In combination with each other or the many artifact accelerants it is easy enough to get the mana for Recoup --> Yawgmoth's Will by turn 2 or 3.
Duress - Black's best disruption.
Extirpate - I only use it to get rid of counters or Extirpates as they are the only cards that really hurt my game plan once I've "gone off".
Necropotence - Turn 1 it's insane; but any later and it kinda sucks. It rarely shows up, though, so drawing it later in the game isn't much of a problem.
Crop Rotation - Grabs Forbidden Orchard or Tolarian Academy. A nice little storm increaser too.
Chain of Vapor/Hurkyl's Recall/Rebuild - These three serve the obvious purpose of allowing me to bounce my artifacts repeatedly, but they also allow me to deal with artifact threats. I've chosen these three because between them it would take three Chalices (all at different settings) to counter all of them.
Well, I think I've explained the cards thoroughly enough. My sideboard at the moment is:
3 Pithing Needle (For dealing with Tormod's Crypt and Withered Wretch)
2 Pull From Eternity (For general 'yard hate)
1 Balance (Fish, Oath, Goblins)
1 Burning Wish
Obviously it needs more though!
Well that's it; so, any thoughts, comments or suggestions? I really want to get this deck working better; at the moment it's brilliant when it goes off but there are still occasions where it just falls to pieces.
Any help would be very much appreciated!
Thanks guys!
