Fade into obscurity: Rayami, Kadena,
Tahngarth, Grismold
Stick around: Atla Palani, K'rrik, Elsha
Somewhere in between: Anje, Chainer, Greven, Pramikon, Marisi,
Volrath, Sevinne, Ghired,
GerrardNow for my reasoning:
Rayami, Kadena,
Tahngarth and Grismold are incredibly niche. Keyword soup, morph, and both types of stranger group hug for each
Tahngarth and Grismold are relatively rare archetypes to be seen and I highly doubt that those commanders will change that. Apart from Rayami they are also pretty lacking in power.
Atla Palani explodes into semi-random fatties, which is essentially Timmy's dream incarnate. I can see that sticking around easily. K'rrik tries to break the color black, which has been, in my experience, one of the most loved monocolors, therefore I can see him stick. Elsha is noncreature, nonland, instant speed
Future Sight in colors that can abuse that. I'm not perfectly sure if Elsha will stick, but I'm fairly certain.
The others fill known strategies, sometimes with a twist.
Black-red got a nice boost in variety this year, but I have my doubts that people will start to change, for example, their Meren to Chainer (similar strategy) or their other Rakdos commanders to one of the three. Chainer enables grindy strategies though, but those aren't well liked at casual tables.
Anje is interesting without the madness part, but the madness archetype itself lacks good cards to be any kind of viable. Most builds I've seen are
Doomsday,
Animate Dead and
Worldgorger Dragon, so nothing new. Greven is super strong, but lacks identity beyond being
Hatred on a stick with bringing really good card draw to Rakdos. He's massively goodstuff and aggro in those colors.
Pramikon and Marisi fill the same niche Queen Marchsa (long may she reign) does - politics! They can shape the game with little effort and build around some board disruption, all being WRX. I expect those two to have a decent following, but nothing major - goad and a
Mystic Barrier in the Command Zone go a long way.
Volrath is a special case: interacting with counters as a massive
Clone on a stick that distributes -1/-1 counters seems pretty goodstuff-y, but I think there may be more to have. I expect him to have some success, but fall off, because he also screams Voltron, which is a weak strategy most of the time in the modern EDH meta.
Sevinne and Ghired, both face commanders, are what I would call a bit lacking in identity. Sevinne supercharges flashback but doesn't enable it, and Ghired just does fatties (albeit kind of aggressively). I haven't really seen aggressive token strategies yet, but rather build-a-board workshops ending with
Craterhoof Behemoth for a massive alphastrike - I expect Ghired to end up the same, especially because he's 5cmc. At least he enables himself.
Gerrard is either eggs or Boros boardwipe protection, which is nice and complements the colors while enabling new brews. But because he's Boros, he will sit upon the throne in the broken
castle that is the currently worst color combination in EDH - although it is getting better.
tl;dr: Some stuff is easy to break (Atla Palani, K'rrik, Elsha), others are perfectly balanced (for example, Greven and Marisi) and will therefore see medium amounts of play and others are so underpowered (Grismold,
Tahngarth) I can't believe they printed it. Some niches were filled (Anje, Kadena) and future design space has been opened (or maybe closed, because Anje could be broken someday). Glad to see more goad and weird design (Pramikon) in the Command Zone.
