Storyline wise I think they wanted someone who didn't know the wider danger of seeing Vorinclex. We the audience knows who Vorinclex/Phyrexia is and why its bad and this makes a strange tension since we know the wider dangers but to Kaya (and the reason of Kaldheim) so far she thinks its a strange monster and seems to have given up on the hunt since she got sucked into Kaldheims conflict. Vorinclex also barley factors in the story and the set as a whole and I'd bet they wanna use Koth when phyrexia takes more of a featuring role.
Sure, that makes sense. But if they wanted someone who was unaware of the Phyrexian threat, it's a shame they didn't just use local characters and let them fight their own battles. I realise that's more a problem of Magic's planeswalker-centric "storytelling" in general than
Kaldheim in particular, but I think this set is one of the most glaring examples of planeswalkers being a detriment to the story. I'd argue all of the planeswalkers felt out of place in this story to various degrees. Maybe not Tyvar, and I liked Tyvar a lot more than I thought I would after reading the preview article about him. But then again, I'd argue Tyvar really didn't need to be a planeswalker, and I'm really sick of every plane we visit having at least one native 'walker because of marketing concerns. It's artificial as hell. Doesn't help that Tyvar's planeswalker card does nothing to reflect his abilities in the story. Still, they could have used Tyvar to check the boxes of both native planeswalker and someone unaware of Phyrexia and have
him hunt down Vorinclex.
Another issue with using Kaya is that - for whatever reason - she's in the Gatewatch now, and I think this creates a bit of an 'Avengers problem' in this story, i.e. it raises the question why she didn't get help from those other Gatewatchers that she was travelling with after
War of the Spark (what the heck became of that in the first place?). Not even against Vorinclex, mind you, but against Tibalt. So imagine you're a Gatewatcher who comes across a known planeswalker villain's nefarious scheme to cause, to quote Tibalt, "UNIMAGINABLE CHAOS" among the realms, and you decide to... just wait for the local clan leaders to gather or something? And not that I'm unhappy to see as little of the Gatewatch as possible, but wouldn't Liliana have been really helpful against all those Draugr? Why were the gods so useless anyway? I swear, that set's story had so many problems. It was the first new Magic story I read after
Dominaria and
Children of the Nameless, and it reminded me again of why that is...
As far as Koth is concerned, I don't look at it as "Koth would have been in
Kaldheim but was pushed out by Kaya", I'm not even upset because they didn't include Koth specifially, and I absolutely agree that he's virtually guaranteed to show up again in the foreseeable future. It's just that he's one of the 'walkers I would have loved to see on Kaldheim for thematic/aesthetic reasons AND he just so happens to have ties to New Phyrexia AND check a diversity box for being black (so no-one can argue you'd lose anything on that front by replacing Kaya). I mean, when most if not all of your 'walkers in a set feel out of place, people will start thinking about fitting replacements that would have made more sense.
In an ideal version of this story, there would have been zero planeswalkers involved (again, maybe Tyvar if he really has to be one) and the native characters would have been allowed to tell their own story. That origin story for Arni Brokenbrow was my favourite, and I would have loved to see more of Inga Rune-Eyes as well as the gods. Inga in particular would have allowed them to include some diversity that's actually meaningful and well-executed. I hated the Commander tie-in story about
Lathril, Blade of the Elves, because it came across like being a freaking GOD does absolutely nothing for you except ruin your eyesight, and the whole thing felt like an excuse to write about a visually impaired character from their own point of view. Wizards even hired a deaf-blind author to write it, but I think she was the wrong pick for that story. I just don't understand how you can create a prominent and interesting legendary character who is
actually supposed to be blind (Inga), but then you largely ignore her and take another random character from a Commander deck (Lathril) who isn't even supposed to be around anymore (I think?) and hire a blind author to make the story all about that character having trouble seeing, while also completely missing the point of what was supposed to be interesting or relevant about Lathril. Like, I'm in no way arguing they should aim to have less diversity and representation, but maybe they should think about how to best implement it for two minutes? They can't just separate this stuff from creative integrity and then point fingers at people who refuse to applaud them (not that Wizards is doing the pointing, mind you, they have their pets on Twitter for that).
Other planeswalkers I really would have loved to see mostly for thematic/aesthetic reasons (if we needed to have any at all) include
- Garruk. Especially since it looks like he dropped the Lannister twins off at Strixhaven and is rid of them. Plus, hunting the biggest game in the multiverse is exactly his thing, and between Vorinclex and the Cosmos Monsters, there would have been prey aplenty. He could even have teamed up with Alrund.
- Ob Nixilis. Going around causing misery and conquering planes is what he does, and I could easily see him take control of Immersturm and rally the demons against other realms. Heck, he would have worked as a better stand-in for Tibalt.
- Ramaz. Mostly because the only things we used to know about Kaldheim for years were that 1.) it's cold there, and 2.) it's where Ramaz likes to hang out. I'm almost always in favour of exploring old places and characters we haven't seen on the cards over creating new stuff.
- Angrath. Metal as hell and even has experience as a pirate. I can't really come up with any reason for him to be there beyond that, admittedly.
