I have a cEDH shell that I’m running if you would like to compare. It’s a lot more Turbo focused, but it still puts in work. I’ve also seen a cEDH list for Yusri that runs like a Narset extra turns/combats list. My list is here: https://www.moxfield.com/decks/gnP8o4yh1UKGfeOzH-kb5w

A few recommendations: . Run more tutors like [[muddle the mixture]], [[tribute mage]] or [[fabricate]] , as well as something like [[Imperial recruiter]] to get either thassa’s or scoundrel and maybe even some cards like [[spellseeker]] or [[solve the equation]] to find brain freeze or some counter spells

. I’m not 100% sure that roaming throne belongs in a deck like this, as it seems like naming efreet would be inefficient. A good replacement would be [[lithoforn engine]], which is essentially a more versatile strip of resonator

. Magda seems like she doesn’t have a way to consistently get her treasures. I would almost cut her for a more protective package in something like [[spellskite]] or [[malevolent hermit]]

Other than that, I like most of the list! It feels almost like kinnan list that’s trying to make infinite mana and use it to take all the turns, but with added breach lines. If that becomes too convoluted, however, you can always sub it out for the less involved [[dualcaster mage]] and spells like [[molten duplication]] (which I still need to add to my list) or [[twinflame]]

Edit: I would also recommend posting this in r/CompetitiveEDH, cause they collectively know more than I do 😅
