All the supposed Oath players out there, Bastian, and you, an
aggro player are the first to come up with a build that isn't just a suboptimal version of someone elses. Kudos to you.

Duress is freaking god in the current meta. As much as I always preferred a minimum of 12 counters in Oath (which help it to play more like Mono Blue on steroids and less like narrow-minded Keeper), 2 Duress 4 Drain 4 FoW sounds just peachy, here.
Visara/Avatar are nothing to Hulk. There are just too many ways to get around it. Tog players just shouldn't lose to this unless they totally screw up, and if they are that bad, you should be able to beat them, anyhow. Spike Weaver is really the best thing you can do against a Tog on the board.
That being the case, Spike Feeder beats out Baloth no contest, because fueling Weaver is a game winner. Baloth can go in the sideboard for the secondary life gain spot.
Deeds are the reason I find this build of Oath tolerable. Without them, you're better off playing white than black.
Crater Hellion is a nice board nuker but not amazing. VS. TnT it might as well be a fog unless they overextended. If you feel it's nuts in your environment, go for it. Otherwise, I'd relegate it to the sideboard for Suicide and whatnot.
Especially with these improvements, Brainstorm is less and less necessary. Impulse finds your key cards (Oath, Deed, draw) quickly and efficiently. If we have room, 2 Brainstorm on top of 4 Impulse is a beautiful thing.
Moxen are lovely for casting things like Oath and Impulse asap, but now that Deed is in the mix there is greater need to keep these to a minimum. Without those, you don't want to load up on things like Wishes, which want a lot of acceleration. I'm thinking 2 is alright, since there's plenty of neat utility you'll want to be using...but I may end up with 3 anyways because there are so many reasons to want to have one in hand.
You still need a good kill and even if Morphling no longer easily beats out everything on the field, he's still your best bet. This will clear a sideboard slot, as well.
Without Balance, there's nothing to Mystical for that you couldn't have just Merchant Scrolled for. No need for this blatant card disadvantage, now.
Sylvan is definitely a beaut. Regrowth is nifty and I prefer to run it on top of the Blessings, but we'll see if we have room.
When you don't run a lot of basics and you don't have white/red for Moon/b2b removal, you have to have some sort of solution. A BEB to be able to Wish for against Blood Moon is dandy (you have enough Islands to reliably do that). You'll just have to play conservatively against Back to Basics and try to keep one green mana free so that you can Wish for Naturalize.
There is no reason to be running land that does not produce blue OR have a utility effect. Fetchlands can get blue duals. Either run a basic land or a City of Brass/Undiscovered Paradise (which also helps vs. b2b).
Library of Alexandria can be questioned. Please note that Oath is not like Keeper. 7 cards for Keeper is what Keeper wants. Oath's standard 6 cards. Where's the 7th? ON THE BOARD. It IS Oath. You have a lot more permanents, so while Library can still crack control games, don't consider it an immovable staple.

Do whatever suits you with your sideboard, but add 1 BEB to your list of Wishable goodness.
I don't know that you want Gush AND Scrying--and I'd choose Scrying first.
You probably want somewhat of a high Naturalize count. They're good.
In addition to the 2nd Morphling, a 2nd Weaver vs. TnT and Tog and whatnot is good, and a Baloth (in place of 2nd Feeder) vs. things with lots of fast damage.\n\n
