Working on a historic Sheoldred/Vito/Aetherflux Reservoir deck - input appreciated

Hello :)

Ive had some fun the last few days with the following deck. It revolves around gaining life, and when I do it drains the opponent at the same time.

I feel like Im missing some speed, faster mana, faster card draw. Any input on how I could tighten it up would be appreciated.

​

Creature spells: 17

4x Orcish Bowmasters

4x Ornithopter of Paradise

3x Vito, Thorn of the Dusk Rose

3x Sheoldred, the Apocalypse

3x Marauding Blight-Priest

​

Non creature spells: 22

4 x Rite of oblivion

3x Go for the throat

4x Sign in blood

3x Aetherflux Reservoir

3x The one Ring

3x Bolas´s Citadel

2x Underworld Dreams

​

Lands: 21

4x Coldsteel Heart

17x Swamp

​

So the combo here is to get Vito or Blight-Priest on the board with an Aetherflux Reservoir. Whenever I cast a spell I will gain life, and whenever I gain life the opponent looses life.

To really go off I would have in addition to the above, Bolass Citadel and Sheoldred on the board. I will typically win the turn I have those 4 pieces assembled, but it is not required.
