Prismatic Vista. Fixing is extremely valuable, particularly a 5-colour land. The other two standouts to me are Mana Leak, which is very close, and, at a larger distance, Nature's Lore.
1) Prismatic Vista 2) Mana Leak >>>> 3) Nature's Lore
If this were a higher-powered cube, which you can tell it isn't by the creatures of the pack, I would pick Mana Leak. Prismatic Vista is replaceable, but you will run any and all cheap, versatile interaction you could find. While Mana Leak is still fantastic, chances are there are far less targets for permission in your cube. In fact, looking at your list now, there are few cards that ask to be countered. Your curve is low and good play takes precedence over putting key cards in play.
Last pick: Wax-Wane Witness.
It's just bad. It's way below the base rate and if I'm gaining enough life for its ability to matter then I'm winning anyways. Your cube isn't high on raw power, but it has great synergies to exploit. A 4 mana bird isn't it.
Demonic Tutor, no question. Scalding Tarn is nice, but completely replaceable. Tutor is not only far more powerful than fixing, it lets you move into all sorts of decks by providing redudancy. In fact, I would get the tutor and try to draft around potentially wheeling Bring to Light because it's fun.
1) Demonic Tutor 2) Scalding Tarn 3) Prismatic Ending
Last pick: Archangel of Wrath. It's 5 mana and two colours before it does something and has no interesting synergies or value beyond raw power, which it doesn't excel at.
My picks are: 1) Fire Covenant 2) Binding of the Old Gods 3) Planar Genesis
Fire Covenant is a beating. Instant, one-sided wraths are amazing. The colour fixing won't be a problem and it's a unique effect. Binding of the Old Gods is just good value. Since multicolour focused cubes are slower, the high cost is less of an issue, while the kill spell and ramping become better.
Last Pick: Croaking Counterpart. It seems nice, but I'm sure that you can find 30 other cards to fit in your deck instead. It seems cool but, in practice, it's little more than 3-mana
Momentary Blink at sorcery speed. I had no luck with it in limited, I doubt it will be different here.
For the next one, I went again with my main cube. But this pack is different.

No fixing and nothing that really obviously stands out to me. Curious what you would take here.

This is a weaker pack, so there are several things you can try. At first, I thought Charming Prince would be the pick since it's a versatile creature and blink is usually powerful. But Portable Hole is so cheap and early interaction is so valuable that I might pick it instead. Notably, I don't think Archaeomancer will come back.
1) Portable Hole 2) Charming Prince 3) Mishra's Factory
The third pick is the most difficult. Ojutai Exemplars has lifelink, which is brutal, but its double-white and only shines in spell-heavy decks, which are hard to draft and not that common. Mishra's Factory does also require good fixing, but it's a 3/3 blocker, a land and leans into a bunch of interesting, powerful synergies.
I could see speculating into Basking Rootwalla, though.
Last Pick: Kruin Striker. I can't see this ever being better than a vanilla, two mana 3/1. You need to play at least another creature for it to be on par, and the ocassional play where you get to turn it into a 4/1 is so irrelevant than I would never run this.
The obvious pick here is Watery Grave, the question is whether you are missing out on Hogaak or Unearth by taking something replaceable.
In my experience, Hogaak often wheels and it works well with Watery Grave. If you take the Hogaak, someone will take the land, so you actually harm your chances by pushing a potential player into graveyard decks. Either way you miss out on Unearth, so I'll take the land.
1) Watery Grave 2) Hoogak, Arisen Necropolis 3) Unearth
Last pick: Thunderbreaker regent. It shoots a creature when it gets killed so it isn't bad, but I would only run it if I couldn't fit something more powerful, interesting or synergetic.
This time, taking the dual looks like a complete trap. Someone will get those mana dorks, which will make your GR deck (already a weak choice), look very sad. You'll also be competing on red because Faithless Looting and Dragon's Rage Channeler are fantastic.
Let's be honest, Hermit Druid is so stupidly broken, easy to splash and unlikely to compete with the rest of the pack that it's my choice.
1) Hermit Druid 2) Unearth 3) Elvish Mystic
Last pick: Dusk Rose Reliquary. I've always though this card was bad. Ideally, you'll sacrifice a creature, but white doesn't always lean into it. Discarding in white is even less likely and discard-heavy decks have little to gain from running the colour.
(in other words, something like Dromoka's Command is effectively mono-white - one of the exciting parts of putting together the cube was that I could throw in a ton of Gx gold cards without having to worry about them taking up limited gold slots). There are also enough copies of Land Grant that everyone in the four-person draft is going to end up with 6-8 copies.
