Notes & Combos
The main idea of this deck is to supplement Snake-Eye combos with Mikanko cards acting as a combination of extenders, disruption and otk tools. Both engines are fairly compressed, with Snake-Eyes being able to set up full combo or close to it off of just Ash and Mikanko having a number of lines to reach Isolde. The deck's biggest advantage is its ability to chew through handtraps, as both engines have lines that let you circumvent the normal summon and make use of misc material that's already been Ashed/Veilered/Impermed. Ohime specifically also feels really well positioned in the current format, partly as a value engine for the longer midrange games that Snake-Eye can produce, and partly because Kagura is really great at breaking boards when opponents aren't trying to set up 4+ negates.
Re: possible changes you could make, adding Called By/Crossout is the most obvious one- I haven't included them because the only handtrap that's really scary 100% of the time is Maxx C, which Droll & Ash can trade with; and this is a format where I prefer having more offensive disruption for my opponents' plays than defensive disruption for my own if I can help it. Ha-Re is the other really significant omission, since she helps make the Mikanko plays less awkward if you're forced to just activate Arabesque and pass for whatever reason. Without running Axe of Fools/Metalsilver I'm not keen on Mikanko Rivalry, though, and the deck is fairly tight on slots. When we do eventually get Spiritwalk I'll want to try her out more. Finally, you could experiment more with expanding the Isolde/Infernoble side of the deck, especially if you wanted to make going into Spright Elf more consistent, but I'm really wary of anything that would reduce the consistency when the Isolde plays are already good enough at going into Princess.
