I decided to go with Chrome Mox maindeck. Chrome Mox enables way more consistent turn 1 Mentor or Narset into LED/Echo hands, there are plenty of blue cards that are unecessary in multiples that I am fine with pitching, and this deck generates so much card advantage that I am fine with the card disadvantage.

Being able to cast Teferi on turn 1 can deal with the Ouphe/Null Rod problem, too. In game 2, I should also have Force of Will + whatever else.

I like Dispatch for cleanly dealing with Ouphe and Plague Engineer postboard, and EE can deal with Mother or Giver of Runes in the Maverick matchup before Ouphe comes down.

Against Null Rod specifically, I might just rely on Force of Wll + Erayo/Chalice/Teferi, since it's likely only ever a 1-of. I'm not sure that Null Rod alone is worth me switching from EE to Disenchant, given how strong EE is with Emry.

I decided to cut Cavern of Souls and Mox Amber for them.

I would cut Riddlesmith before cutting the first Mentor. Riddlesmith can help with the engine, discarding Echo and increasing the card quality of the hand, plus putting stuff in the yard for Emry is nice, but Mentor is how I actually win the game. The sooner I can resolve a Mentor and start chaining cards together the better, and I certainly want to be able to stick one through removal/countermagic/etc, and they are great in multiples. I only need a single Riddlesmith to acquire the effect, and they aren't necessary for the deck to function.

I'm fine with 2 Riddlesmith. With Erayo, I do appreciate having the additional 4 2cc creatures for the curve in addition to Chalice, but I shouldn't really need more than that, considering how much Chrome Mox helps for casting a 3cc spell on turn 1.

EDIT: Riddlesmith is really strong, but Erayo is even stronger, and I'm almost wondering if I shouldn't just be on 4 Erayo instead. Chrome Mox helps make turn 1 Erayo pretty consistent, and turn 1 Erayo is absolutely busted. I'm going to go with 4 Erayo for now. I'll update my list in the OP.
