MTG Salvation

I'm looking to build a flexible Commander deck that I can readily sub out 40 cards for and run as an Oathbreaker deck- this is fully experimental and not expected to necessarily be competitive (in either format) though being able to run "one" deck in both formats is highly appealing to my love for general deck flexibility.

So, there are a couple of questions:

Which legal Planeswalker is "best" (or at least most interesting) and why?

What signature spell is good in the 99 or in the Oathbreaker command zone?

For convenience, the following are the commander-legal Oathbreakers:

Aminatou, the Fateshifter
Daretti, Scrap Savant
Estrid, the Masked
Freyalise, Llanowar's Fury
Lord Windgrace
Nahiri, the Lithomancer
Ob Nixilis of the Black Oath
Rowan Kenrith x Will Kenrith
Saheeli, the Gifted
Teferi, Temporal Archmage

Smart money would be on either Aminatou or Teferi. Aminatou because she comes down early giving you access to your spell, and has good colors. Teferi because he's already known powerful commander. Although he might lose a lot of luster without some of the fast mana that really sends him over the top.

Daretti with Scrap Mastery has his signature spell is neat.

My bet is on Saheeli. Izzet artifacts is really easy to break in half, even with the expanded banlist.

For trying out Oathbreaker i went with a different approach. I chose to convert one of my EDH decks (Ezuri, Renegade Leader) into an Oathbreaker deck (Vivien, Champion of the Wilds + Genesis Wave) with one of the PWs in the 99 as the new commander and only cards in the 58 that are part of the 99. That way all i had to do is cut down the list and swap cards in and out the command zone.
So far the deck has been working great and i got an easy glimpse into the format. I've linked both decks above, if you want to get an idea.

I'll convert Edric, Spymaster of Trest into Nissa, Steward of Elements + Noxious Revival, Harvest Season or Notorious Throng propably.

Actually, Saheeli, the Gifted is banned: https://weirdcards.org/oathbreaker-ban-list.

She is the most broken XD. Only walker to be banned in the format funny enough

I was unaware of the Saheeli banning! OP has been suitably adjusted, I'll have to eyeball the banlist again- I knew fast mana was out at least.

Lots of solid feedback all around so far.

I can definitely see the value in these options, though the value engine offered by Daretti also seems fun. What signature's do you like for Teferi or Aminatou?

Aminatou...probably demonic tutor for blink cat? Boring but effective.

Teferi could run some version of fabricate in the same vein, to fetch his infinite combo. Not sure if that's the best use, though, it is a bit slow. Maybe transmute artifact would get there, with enough big mana rocks I think you can infinite on 6 with that bad boy. You need 6 mana (minus the cost of the sacrificed artifact) to get it into play, and then 4 left over to actually activate it (and then enough big mana rocks left that you can generate enough mana to recast teferi after he dies, which means he's untapping either 6 mana, or 5 mana with a couple extra at the start).

So for example, T2 fellwar, T3 thran dynamo into worn powerstone, T4 play teferi with 4 mana leftover, untap into 11 mana, cast transmute sacrificing the fellwar stone going to 7 mana, activate chain veil going to 3 mana, go infinite. Actually with that nutty start you could get there off fabricate, but I think transmute will get you there in situations that are a little closer, mana-wise.

Not that either of these would be my cup of tea personally, but you asked what the most powerful options are, and those are my guesses.

Doesn't have to be the best option, if you're more into something more "fun" than I'm open to thoughts. (Gods know I'm no spike, which is part of why I'm only buying half-in on the format as it is, since it looks to be about as spiky as Commander spin-off can get.) I find it hard to believe there is much better than Demonic Tutor or The Elderspell for anyone with a black identity, unfortunately. Maybe a ramped out Torment of Hailfire or some cheaty Exhumes?

At least for my commanderoathbreaker, W&6, I've found summer bloom to be pretty bonkers. Consistently untapping with 6 mana turn 3 without the commander-only fast mana is pretty nuts. Even if they were black-green instead of red-green, I think I'd run the same spell. But they do get extra benefit from it, since they can hit the board faster than any other oathbreaker (and help ensure extra land drops), which makes the tempo swing more insane.

Not exactly what you mentioned but I’m thinking of making a sephara, sky’s blade flying/angel deck that can be run ass a serra, the benevolent oathbreaker deck.
Going to be running flying tokens flying “hatebears” some angels and utility equipments that damage on combat.
