Very interesting. 5/4 for four mana is a solid statline, although a bit awkward if you want to go for commander damage. On the other hand, janky keyword voltron! I don't believe there are any ways to get double strike in those colors, but all the other keywords are pretty doable, and quite scary in multiples.
Also functions as a Sultai commander that *doesn't* work well with graveyard-based strategies, which is sort of different. Exiling things that die is a pain for many decks - shuts off recursion and death triggers. Rayami may draw a lot of hate as a result... but if it has hexproof and indestructible, then there isn't much your opponents can do.
....I've jokingly considered Brago
processor tribal before (running a bunch of
Oblivion Ring effects too) to deal with a
Mairsil, the Pretender deck in my meta. Now I'm even more tempted....
