Full disclosure, friends: Kaya the Inexorable was the Planeswalker that I was least excited about when Kaldheim was fully spoiled. Please don't consider that a poor reflection on Kaya herself! I really like the character, and honestly, I enjoy her in the Black/White space more than Sorin. 

It's just that WotC has more or less "solved" Kaya in terms of her character and abilities. She exiles things, and can sometimes turn herself into a ghost, or prevent other things from being ghosts. Right? Something like that. Anyway, that design space doesn't seem too vast, so it's hard to build a lot of variations on that theme. 

Luckily, there's some text on Kaya's Plus and Ultimate abilities that seem a little more interesting. Her Plus ability rewards our creatures for dying or going into exile, and her Ultimate ability incentivizes us to play Legendary permanents so that we can recast them if they meet an untimely end. 

I think we can work with that:

The Game Plan

Our creatures aren't generally large, but we have lots of sneaky spells, onboard tricks, and Planeswalker abilities to exploit that will give our opponent fits. First, take note of all the different creatures we have that we won't mind sacrificing: Doomed Traveler, Imperious Oligarch, Beskir Shieldmate, and Debtor's Transport all offer us some extra bodies on the way out. Crow of Dark Tidings serves as more fodder to hit with Unburial Rites or Kaya's Ultimate ability, and Black Cat can hopefully nuke our opponent's luckiest options. 

We're also flush with as many Legendary creatures as we can fit; thanks to WotC's design protocols over the past few years, we've got more Legends at Uncommon than we've had in a long time. Whisper, Blood Liturgist shines here as a way to capitalize on those death triggers and keep cards flowing between zones. Kongming can buff a flooded board of otherwise shrimpy bodies and tokens. Firja brings a body that's difficult to kill in combat and some lifelink that will prove to be annoying, as well as valuable card selection that might also fuel Kaya's Ultimate ability. If we happen to have several Legends going, Arvad the Cursed will provide a massive boost. 

The removal here is pretty good! We shouldn't suspect any different of course—Black/White is a color combination that should be flush with options. One thing to note here is that Big Game Hunter and Reprisal are a bit restrictive in what they can hit, but they're a nod to the massive beasty Vorinclex that Kaya is hunting in the Kaldheim story. Afterlife is a more generic flavor for Kaya, and Mortify is just an incredible spell. Kaya's Onslaught and Dogged Pursuit are other flavor nods, but both spells are totally fine. The Onslaughts are paired with the Doomskar Oracle to provide a guessing game to the opponent if we choose to go the Foretell route; keep that in mind on games when we draw the Oracle. 

Lastly, we've got several card selection options that heavy White decks are generally unaccustomed to. Village Rites can give us some cards at instant speed—cheaply—while also taking advantage of death triggers from our smaller creatures. Purge the Profane is a good old fashioned 2-for-1, and Skull Raid is a new card I'm excited about. If both us and our opponents are low on resources, it can end up being a Divination, Mind Rot, or splitting the difference and I appreciate that flexibility. Keep in mind that unless copious mulligans have happened, Skull Raid seems like an unlikely Turn 4 play.

The Rares

This guy's mostly in here to shore up the Legend count, but in a field where Planeswalkers are usually the opponent's best possible card, we're likely to at least snag a few drains with the good Consul here. Kambal isn't the strongest card, but his ability is low-key very disruptive and the body we get for him is totally acceptable. 

A nod to Kaya's profession (Bounty Hunter might be a bit more of an accurate nod, not 100% sure, but Kaya sure has assassinated like...all of Magic's more notorious ghosts in her day) while also taking advantage of our death triggers. Let's not develop too much sentimentality for our creatures, because there's no telling when one of them might get chucked to kill something dangerous. 

What a weird card! It's super slow, but they can end up giving us a ton of cards with the Black ability, and if it happens to be a creature that's been targeted by Kaya's Plus, then I'm not even sure I can add up how much we'll be ahead. This is one of those "I got this in a draft and it was awesome, so I have to play it again!" cards. Except that I never opened it in a draft, just in various prize packs. But I've never played it. so the mystery still remains. Let's figure it out together. 

I wanted more Legends, and Selenia is a really cool card. She's nigh-unkillable (assuming our life total is reasonable) and if we let her go like poor Crovax did in the Weatherlight saga, we can bring her back for more action later when we Ultimate Kaya. Her stats aren't super dreamy, but just imagine her in play at the same time as her former beloved's callback Arvad, and all of a sudden she hits like a truck. 

Unsung Hero

Unfortunately, Whisper doesn't generate card advantage by herself; you have to get rid of two creatures to get only one back. That doesn't seem like a great deal on its face. But consider this: most of our cheap/early creatures generate some kind of effect when they die, a few others generate an effect when they enter the battlefield, we can use this ability at Instant speed, and we get all of this on an Uncommon creature that's otherwise fairly cumbersome and might dodge enemy removal. Now things start to look substantially more appealing! Bonus points for having a cool card name.
