In Episode 53 of Faithless Brewing we looked at Lutri, the Spellchaser, back when Companions were still trendy and Friends was still on Netflix. Most of our Otter decks were in Blue Moon shells, but I was interested in a Pioneer deck that used Lutri as a main deck card to facilitate a Neoform combo. Five months later, they keep printing cards that work in this deck, getting closer to something magical.

Sea Gate Stormcaller is the big new addition. It is both a value card when combined with Opt, and a copy effect that can start the combo on four mana if there is a three mana creature already in play.
The combo works like this: play Stormcaller, play Neoform, and sacrifice the extra 3 CMC creature. Stormcaller’s copy ability now triggers and resolves first; use it to fetch Naru Meha, Master Wizard which copies the original Neoform still on the stack. When that copy resolves, fetch Spark Double, clone Naru Meha, make another copy of Neoform, fetch another Spark Double, and repeat.
This is actually a way to combo that wins through Teferi, Time Raveler. Additionally, Stormcaller is ANOTHER 2 mana body to be fodder for Eldritch Evolution (cast Eldritch Evolution sacrificing a 2 drop, copy with Expansion or Lutri, the Spellchaser, then fetch Naru Meha to copy Eldritch Evolution for the same combo sequence described above).
A concern is that we don’t have a lot of spells for Stormcaller to copy. I was curious about adding the 4 Opt anyways, so I don’t mind Stormcaller pushing me in that direction, but the overall spell count is on the low side.
Silundi Vision is another great card in the deck. We have very few turn 1 plays, so a tapped Silundi Isle on turn 1 is totally fine, and in the midgame it faux-tutors for our key Neoform, Eldritch Evolution, or copy effects.
It is an open question whether you need or want to add red. Fire Prophecy was underwhelming for me in previous builds; I think just being all in on the combo in Game 1 is totally fine. Another open question is do you need want another Chasm guide or maybe even a Master of Waves? These allow you to finish the Naru Meha sequence strong, but they might be overkill.
