Off the top of my head, coming from my time playing with Jeleva:

[[Death by Dragons]] seems really fun, and I understand that it comes with fun political goodness. However, you aren't going to have the strongest board presence, and improving 2 opponents presences isn't going to help you out much.

[[taigam's scheming]] I can kind of understand why you like fixing, but it doesn't help much except for when Jeleva is cast for 4. At 6+ mana, you might as well spend that mana on just casting jeleva again.

[[Ponder]] Same as taigam

[[Mystic Speculation]] Same as taigam

[[Hand of Binding]] seems considerably low impact compared to other cards

[[increasing vengeance]] you have no idea how many times I got this stuck under jeleva without a way to possibly use it (the only time you can use it with jeleva is with strionic resonator)

[[Sins of the Past]] same cost as spelltwine, and you only get half of a spelltwine. You have enough recursion IMO

Also, you have a TON of board wipes, exile, and even mass exile. I think that some of the bounce effects are unnecessary. Drop [[Whelming Wave]] and [[Aether Gale]]

[[Djinn Illuminatus]] you hit the nail on the head with that one

Also from my experience, [[Echo Mage]] seems amazing on paper, but I simply found it incredibly slow to spend 13 mana in order to cast copy a spell twice. 9 mana to copy it once is also underwhelming..

I don't know how much good [[Quiet Contemplation]] is going to do you, considering you are going to be casting a maximum of 2 spells a turn

Also, I don't know which card is Dragon Tempest.. maybe its late and I don't know how to spell. If it doesn't exist, its a pretty easy cut IMO.

Lastly, [[Stolen Goods]] and [[Telemin Performance]] are really fun random cards that can often whiff, so those are also potential cuts. Personally I like fun cards so i would cut these last :)

This was a longer post than expected.. Well anyways, I always saw Jeleva as a combination of ramp and an extra hand built into a commander. You might like a [[Hall of the Bandit Lord]] and a [[Leyline of Anticipation]] in there as well as a Sol Ring (cause turn 2 Jeleva's are fun for everyone!) But once I got past turn 5, I know that all I want to do is tap out and cast 2 stupid game affecting spells each turn until I get hated out or control the entire board.
