Jeleva EDH - big spells are better (EDH / Commander)

My initial build of this deck revolved around topdeck manipulation geared towards an early win by casting some powerful spells with Jeleva as quickly as possible. This worked for a time, but my meta has become more tuned of late with more efficient removal and interaction. As a result, this glass cannon style of play became less and less effective. While still looking to win through one of a selection of potent sorceries, my current build for Jeleva is more of a control list that looks to abuse copy effects and recursion for value, eventually winning through storm. Jeleva can act as a win-con still, but her main role in the list is card advantage and disruption.

There's a pretty strong removal package built into the deck, including multiple boardwipes/mass bounce effects. This is fairly crucial to the plot as unless you're able to go off early with Jeleva you'll need to control the board to secure a position in the mid-lategame where you can fire off multiple high-impact spells per turn. There's only a couple of counterspells included (Red Elemental Blast, Mystic Confluence), and these aren't exactly premium countermagics. However, I believe them to be best-in-slot in Jeleva: their primary role is to protect our commander and big spells from interaction whilst on the stack, and none of them are total whiffs when exiled under Jeleva. In fact, REB is a pretty gnarly inclusion as it provides with some reach into blue enchantments and planeswalkers (for instance, Rhystic Study, Estrid the Masked).

Some notable value pieces that I absolutely love in this list:
Oblivion Sower - allows often cost-free big ramp to accelerate you into the lategame.
Fervor - bit of a pet card to be honest, but often flies under the radar and unlikely to attract someone's removal when there are so many better targets out there. However, it allows you to swing with Jeleva as soon as you resolve her, and provides all those Construct, Drake, and Rite of Replication tokens with haste too!
Mnemonic Betrayal - super on-theme, and also just really good. Cast this lategame after people have used their removal and recur everyone else's biggest threats.
Kess, Dissident Mage - If you can cast her late she basically takes over as the deck's Lieutenant, especially once you have enough mana to recur all your nastiest spells.

Notes to self - out:
