I disagree about situational card draw for the same reasons I don't think Wicked Wolf or Beast Within is good for green— it's too much of a cheat trying to get around the color's weakness altogether by just using in-color conditions and effect stylings, where the result is much the same. White not getting card draw means white not getting card draw. There's some small room for flexibility there, but it can't just be very typical easily built around things.
WotC has been trying 'each player draws a card' in white, the latest example being Shatter the Sky. I think it's promising territory to increase cardflow in white without giving it real card advantage.
One thing white could do with more of, I think, is more, better, perpetual late game value. Cards like The Circle of Loyalty, and more of them that don't encourage relatively aggressive small creature decks. Repeated effects that create tokens, buff creatures, return cards from the grave, remove permanents— cards that threaten to just take over the game with value. Green gets lots of cards like this, Nyxbloom Ancient with the newest set, while White's big lategame cards can often be more one-shot like Planar Cleansing, or rather contained, like Zetalpa, Primal Dawn.
I think white could also afford to push more with land filtering cards like the upcoming The Birth of Meletis. At least more basic plains tutoring, but perhaps white could also get some Lay of the Land type cards, cards that return lands from your graveyard to the battlefield, creatures that tap for white mana but only to cast creatures, or to cast artifacts or enchantments.

Of course, much of this could instead be phrased as a Completion keyword that does the opposite of making the creature an Artifact when fully Completed (which is to say cast at highest cost) so CMC inflation doesn't set in, possibly a variant of Level Up that gives parts of the final statline gradually or a subset of Transform that shifts the creature from Mirran to Phyrexian.
Also, it's spelled "Incomplete".

Spark of Madness 2BR
Creature - Elemental
Haste, Seeker (While searching your library, you may exile up to one card with Seeker from your library. While it's exiled, you may discard a card to cast it as though it were in your hand.)
When Spark of Madness enters the battlefield, take control of target creature an opponent controls until end of turn. Untap it and it gains Haste.
Unearth 3BR
2/1
---
The wording on Seeker makes it so that you can discard a card to get this back after Unearth exiles it.
THE LIST HAS RETURNED!
Chainbreaking X {cost} (This creature comes into play with X -1/-1 counters on it. You may pay {cost} to remove a -1/–1 counter from it)
Formation X (whenever this creature attacks or blocks, it gets +X/+X until end of turn if another allied creature with Formation is attacking or blocking)
Spellblock X (whenever a sorcery, instant or ability would target this creature, counter it if its CMC is X or less)
Intercept {cost} (You may cast this creature for it's Intercept cost during an opponent's combat step, before blockers are declared. If you do, put it into play blocking target creature and return it to its owner's hand at the end of the combat step)
Incarnate {cost} (When you cast this spell, you may cast it for it's Incarnate cost. If you do, it comes into play as an X/X Spirit creature, where X is this spell's CMC)
-Lifelink, Wither, Infect etc. all apply to the creature and have use on spells.

After everything that's happened, she just wanted to have some fun doing things she wanted as a child.

Next: A colorshifted 'Walker that appeared in Lorwyn, but the Colorshift has to make some sense. No random White Liliana, you can only do that if you have a reason for Liliana to go 'Imma be a White ***** now.'

Building Flames 3RRR
Enchantment
Cumulative Upkeep: Deal 2 damage to target creature you control, then put a 1/1 red Elemental creature token onto the battlefield.
---
It's an odd way to use Cumulative Upkeep. Seems crazy expensive for it's price, but it's 'downside' is utterly irrelevant once you have something that gives all those Elementals +2 toughness. Plus, some decks or board scenarios make it crazy strong. It's meant for a WBR weeny swarm. That's apparently something that isn't worthless.
