What If? - How A Change To Hybrid Mana Would Impact cEDH

Deathrite Shaman by Steve Argyle
Hark, dear reader! I'm not advocating for a change to the hybrid mana rules in Commander! This isn't part of my Revising The Rules series where I try to put forth an argument for tweaking the basic rules of the format. This is no more than a hypothetical and an attempt at excising a question that's been rattling around in my head for a few years. I'm interested in the implications, not the justifications.
So rather than try to nail down sufficient wording that would cover all edge cases and satisfy nitpickers, I'm asking you take a leap of faith and imagine a world where for some reason it's now possible to run Sundering Growth
Ashiok, Dream Render
Ashiok, Dream Render
Having said all that, Ashiok is an effective stax tool for shutting down graveyards and tutors of any kind for as long as they stick around. Ashiok (along with Shadow of Doubt
Deathrite Shaman
Coincidentally the card most likely to have an effect on the meta if hybrid rules changed is already the most played hybrid card according to the cEDH staples list. However, Deathrite
In the case of a far less restrictive approach to color identity (again, not something I'm advocating for) Deathrite would go from its current status as an all time staple to utterly ubiquitous. It's hard to think of a deck with green or a deck with black that wouldn't want it. Nevermind the two activated abilities and the chance to eat through graveyards, the ability to produce mana alone is worth the price of admission.
Green decks aren't exactly crying out for more mana dorks given the plethora they already, but I can't see them saying no to another one. As for black decks, the closest thing black has to a dork is Blood Pet
Dovescape
Could Dovescape see play in mono white stax lists? At six mana, I'm inclined to think no, but it does make for an awfully difficult lock. Short of Boseiju or an Outland Liberator-esque effect, there aren't many answers to a resolved Dovescape. Pair it with Elesh Norn, Grand Cenobite
Dryad Militant
Non-human creatures with stax effects that can turn themselves sideways are precisely what the good doctor Winota, Joiner of Forces
Fiend Artisan

Providing enough fodder, the Artisan could find its way into Rakdos or Dimir, where it could bring a Dockside Extortionist

Judge's Familiar
A running theme with cards on this list is borderline playability on account of existing cards filling similar roles. Judge's Familiar
Meanwhile, Edric, Spymaster of Trest
Lurrus of the Dream-Den
Lurrus, scourge of constructed Magic on an inter-format scale and the only card banned in Vintage for being too powerful, is not much of a force in cEDH. It's a vital tool in certain Razaketh combo lines, but it's far from the terror that it made itself everywhere else. A change to the hybrid identity wouldn't change that, though it could open up interesting possibilities both as a companion and in the 99.
As a companion, the only real options are Oswald Fiddlebender
Within the 99, it's easier to see. Oswald is again the first deck that springs to mind given his penchant for sacrificing and filling the bin, but decks like Teshar and Koll, white decks that want to manipulate artifacts and the graveyard are all possible homes for Lurrus.
Lutri, the Spellchaser
Ha, just kidding. A total abolition of color identity still wouldn't see the little Otter go free, because it isn't hybrid mana that's holding him back, it's the fact we no longer have a "banned as commander" list. We should. Anyway, even if we could run Lutri in the 99 or as a commander, we wouldn't. Contrary to what some believe, Lutri will not go infinite with either of Heat Shimmer
Manamorphose
Krark, the Thumbless

Saheeli, Sublime Artificer
The ability to make a slew of artifacts as you execute your main gameplan is perfect for Urza, Lord High Artificer
The -2 is less inspiring, but possibly relevant for Magda, Brazen Outlaw
Vexing Shusher
This is one I'm really confident we'd see shoot up in popularity. Giving a deck like Godo or Yisan to not only reliably protect what they put on the stack but participate in the table's attempts to stop another player from winning seems like a winning combo. Vexing Shusher
Wild Cantor
An unassuming card, but possibly viable in this hypothetical for the same reasons Blood Pet
Zirda, the Dawnwaker
Like Lurrus, the challenge of making Zirda into a companion is probably much too difficult to be viable. But giving sans red or sans white decks another way to go infinite with Basalt Monolith
Guess Work
Really, this is just a stab in the dark. It's hard to know what sort of combos and interactions would suddenly become possible with a hybrid rule change because nobody has put much real time or effort into brewing new decks under such conditions. This isn't like no banlist cEDH where people have actually played and studied the format.
I think it's safe to say the impact on cEDH would be negligible. Low color decks starved for staples and looking to branch into unique effects outside their current reach would receive a small boost, but the majority of the meta would barely notice. At the point you're in three colors, you already have access to more than half the cards ever printed in the history of the game, so the introduction of just a few more is unlikely to make a difference. It's rare that one of those three colors can't sure up the weaknesses of the other two.
Or am I overlooking some incredible interaction? Do you have a brew that can't take off without a certain hybrid card? If you think I've missed something, click here and you can see every Commander legal hybrid card. Let me know in the comments!
