No need for the
opt's other than for scrying/draw altough it's a cheap way to mill the opponent with
Drowned Secrets.
The general sequence with Naru Meha is that you first cast
Release to the Wind (targeting any nonland permanent on the board). As Naru Meha has
flash, you cast Naru Meha targeting the
Release to the Wind on the stack. This copies the spell and you choose Naru Meha as the target, which exiles Naru Meha. You may now cast Naru Meha for free and at instant speed due to
flash, copying
Release to the Wind and repeating the cycle as many times as you'd wish.
I've thought about the combo a bit more and since it's important to have an early
Drowned Secrets the deck needs to run many copies of it, which are unnecessary for winning. I think a self-mill option (not infinite) could make sense for the deck and add another win condition. You could then add Crucible of the Worlds and that 3G
World Shaper creature that let's ypu put all lands into play when it dies (thus sadly does not work with
Release to the Wind). Theres also the new
Enhanced Surveillance (1U) that let's you shuffle your graveyard back.
