For your information, we're hoping to create a stickied thread at the top of the forum so that any visitor understands exactly what cEDH means in comparison to the normal Multi-player forums, so we're hoping to dispel that confusion relatively quickly. That being said, the general consensus for cEDH decks is that card choices and deck strategies are created to maximize win percentage at the cost of theme, pet cards, etc. Card choices are generally dictated by what is the best for a particular strategy and not what you can/can't afford. We'll figure out a more concrete list shortly, but these are the building blocks of what defines a cEDH philosophy.
That said, I like your decklist a lot. I especially like the Shaman's Trance tech. That's a pretty cool interaction! Have you considered Mnemonic Betrayal instead? They're very similar to each other in function and the art is WAY cooler on the Betrayal. However, the Betrayal does exile the cards you cast as a replacement effect, which shuts down the loops you've mentioned.
Either way, this is a cool take on Jeleva that's very reminiscent of Moxnix's Jeleva Storm thread.
Quote from Myojiin »Turns effects are a holdover from casual Jeleva and don't cut it in cEDH metas. Doomsday is also quite a bit less relevant than it used to be, though reversemermaid is starting to cycle back to that kind of effect. You can find his mediumly relevant and less mediumly updated list here.
A more current and up to date build would likely be here though, but note that Kess v Jeleva is a different discussion and mostly meta relevant. If I were to be playing a Grixis Storm list nowadays I'd be erring more towards the build that Wedge has in the second link.
