For those who didn’t see my original Obscurity deck idea:
The concept was to utilize Celerity with Obscuring Blows (OB), creating immense burst damage. The issues people had in trying it was that it was too slow and hard to keep. The later suggestion I made was in utilizing Elkowl, as Elkowl is a 3 mana minion that can also gain celerity. After finally getting OB, I tested these ideas myself.
In agreement, I aimed to make the deck faster. Dagger and Beastmaster, gone. Spelljammer, too slow. Tried Alcuin, too slow and doesn’t fit right. Aethermaster was too slow, gone. Killing Edge is almost too slow! So it got faster…and faster…and faster…By the end, this was an aggro deck and my first ever one. Because it’s my first one, I don’t know how aggro players would say this compares to others, but for my 1st time experience, holy hankies Batman, this is blazing.
Here is the current deck I have right now:

This deck is hard to pilot properly. I’m not good enough to properly pilot it myself, yet. This is a hard deck to pilot and it will require time for anyone to learn.
I don’t know of a picture more perfect to represent everything about this deck than the position I present below (see Aggro Obs. in Practice).
-Importance of positioning
-Level of difficulty in decision making
-Amount of punishment for failed decision making
-Burst and damage potential

(Two tidbits about this: I should’ve placed Elkowl in front of Lilithe and I replaced Pheonix Fire into an Inner Focus)

Quick Bits and Suggestions on how to play the deck
-It’s a load of fun
-Play as Reva. I haven’t made this switch yet, but (1) people expect backstab from kaleos, (2) this deck can use literally 0 backstab minions to be useful and would help in leaving the opponent unsuspecting, (3) Kaleos’ backstab is usually not necessary for how this deck carries out and its speed.
-If playing as Reva, Juxtapositions may be unnecessary, leading to 3 more slots to be able to fill! Haven’t tested this theory out yet.
-Initial game replaces:
Top replaces - Sojourner, Abjudicator,
Next tier replaces - Killing Edge, Primus Fist, Pheonix Fire (1 is fine, always replace a 2nd)
-Always place Elkowls as close to the generals back as possible, you never know what you’ll get. (If P2T1 though, you can Elkowl in anyway you see fit, as Flying is still possible)
-Always spend your time on both players’ turns counting possible damage, with the amount of varying options available to the player, trying to maximize can be pretty calculating intensive[/details]
[details=Deck Upgrades]I don’t have all the cards available to me. If I could make changes:
-Adding-
Tusk Boars
Lantern Fox (PF card draw)
Xho (maybe)
Manaforgers in place of Abjudicators (preference)
-Removing-
Sojourners
Kataras
Juxtapositions (maybe)
Why Elkowl is so great for us
Any keyword Elkowl will get will usually be of relevance for us. Provoke Elkowl behind general leaves backstab dmg relevant, Celerity for 2x hits, Flying is a free MDS, Rush (
). The worst two for us are blast and ranged, leaving us with more keywords in favor for what we seek to do than not.
For anyone who ends up trying it, I hope you have a blast with this deck. I admit it’s no longer too OB+Celerity present, but it’s still there and the damage burst potential from it is very much still existent. I hope you have fun and let me know how it goes! 
Edit: Considering Manaforgers as an addition/alternative to Juxtapositions, Abjudicators and/or Kataras.
