A Tier List of One-Mana Creatures in cEDH

Hiya, folks! Welcome to my first of many cEDH Tier List articles covering the lesser-talked about parts in a cEDH deck: the individual cards themselves! This month I'm covering a topic that is near and dear to my heart, one-drops, so I've scoured the top-performing decks on EDHTop16 and put together this tier list of some one-drop creatures you can expect to see in any given cEDH game.
S-Tier
Esper Sentinel
Starting things off with the premiere one-drop for white, it's Esper Sentinel
Birds of Paradise
The only other creature in our S-Tier, we have the greatest mana dork in the game, in my opinion, Birds of Paradise
A-Tier
Tinder Wall
Tinder Wall
I have heard this is an all-star Najeela, the Blade-Blossom
Deathrite Shaman
The first of my potentially many hot takes on this list, I think Deathrite Shaman
This card will appear in most BG+ lists, and can commonly be thought of as a Birds of Paradise
Sure, the odds of you and your opponents using fetch lands in this format is very high. Similarly, Underworld Breach
Even as a DRS-hater, I have been swayed into using it in my personal Reyhan, Last of the Abzan + Kraum, Ludevic's Opus list. I'm not happy about it, but it has been fine. Solid A-Tier objectively, even if I want to put it lower.
Delighted Halfling
A newcomer to the mana dork family, Delighted Halfling
Legendary creatures are often considered to be "uncounterable" in this format anyway, but Delighted Halfling just gives you that extra assurance that you can get there without worry (especially on game-winning legends like Emiel the Blessed
To add even more for this card, Delighted Halfling specifically says legendary spells. This can lead to some game-ending artifacts being unanswerable, like Bolas's Citadel
If your list happens to run a handful of legendary permanents and you're in green, you should often be including Delighted Halfling in there.
B-Tier
Dragon's Rage Channeler
Surveil is an incredibly powerful mechanic, as we are currently seeing with the new surveil land cycle from Murders at Karlov Manor, and Dragon's Rage Channeler
The downside of DRC is that it requires the casting of noncreature spells without a clear payoff by itself, which can often be extremely punished by cards like Mystic Remora, Rhystic Study
Serra Ascendant
Similar to DRC, Serra Ascendant was once a mainstay in many cEDH lists. Arguably one of the strongest turn-one plays you can make that don't draw you cards, Serra Ascendant abuses Commander's starting 40 life total to get you a one-mana 6/6 flier with lifelink. The unfortunate part about Serra Ascendant is that sometimes it just doesn't feel like enough.
The recent months have shown an increase in creature-focused board states, which in turn has also increased the amount of answers people have for problematic creatures. Even though it is a brilliant attacker in Tymna the Weaver decks, there are many times where your Serra Ascendant won't go unanswered for long.
Lastly, since most cEDH decks utilize their life totals as a powerful resource, there are many times where drawing this card when below 30 life effectively means a dead/useless draw. Lifegain strategies are more or less non-existent in this format, and unless you are running cards like Solitude
The Hierarchs
This wouldn't be a one-drop tier list if I didn't at least mention the Hierarchs, those being Noble Hierarch
Along with providing access to three colors, they also have the exalted keyword. Most of the time, exalted doesn't really matter. However, if you're playing a deck that synergizes with combat damage in some way then you should be running one of these if you're able. It might not seem like it, but turning your 2/2 attacker into a 3/3 might mean the world of difference for if it will connect or not. It's a small thing, but something I definitely think people don't talk about enough.
Here's hoping that Modern Horizons 3 gives us more options for these (fingers crossed for a Sultai or Temur Hierarch, please, Wizards, I'm begging you).
C-Tier
Single Mana Dorks
Not much more to add here personally, we've talked about the different types of mana dorks at all other tiers. This section is specifically for mana dorks that only make a single type of mana, things like Elves of Deep Shadow
These are commonly run in one- to two-color piles, or the occasional three-color pile that needs just a ton of mana (like Tayam, Luminous Enigma
Once you start getting into more streamlined three- to five-color lists, it starts getting harder and harder to justify having a mana dork that only makes a single type of mana. Unfortunately mono-green, Golgari, and Selesnya are not really at the top of the food chain at all (and are often only successful at all in the hands of some of the most dedicated pilots out there).
Ragavan, Nimble Pilferer
My biggest hot take, and something that I think not many people in the cEDH community are ready to hear, is that Ragavan is bad. Big ol' stinker.
An all-star in 60-card formats, it's undeniable that Ragavan is an extremely powerful card. However, with how cEDH games are structured, Ragavan often comes up short, especially given how creature / "board invested" many decks have become currently. A 2/1 for 1, or 2 if you dash it, that also can potentially net you a Treasure and a card from our opponents deck sounds good. In practice, though, at almost every point in the game besides the first one to three turns, Ragavan is just not very good. Opening on a turn one Ragavan feels amazing, but drawing the silly monkey when you're at the 'time to win' stage of the game feels worse.
For all those reasons, Ragavan is pretty much... fine. If it were to suddenly go away, then folks might start using their turn one Imperial Seal
It isn't Dockside Extortionist
Anything Else
There are a lot of one-CMC creatures that I didn't mention in this article, either because they aren't super common among the 'top' decks or because they are parts of fairly niche archetypes or combos that you might find only in a handful of spots in the entirety of the format. Things like the one-drop Dwarves that Magda, Brazen Outlaw
There are many, many more one-drop creatures that can find niche homes in various cEDH lists, and not being on this tier list doesn't mean they aren't any good there.
That's all! Expect to see a similar article from me next month, where I'm going to be covering the commonly seen 'Free' spells in cEDH (and even some that might not be so common, but you might want to consider running).
