Most new Magic sets have a few standout cards that look like a shoe-in for existing cEDH decks. The Lost Caverns of Ixalan, though, not only has some really interesting cards that not only can easily be slotted into existing decks, but may alter the commander landscape just a bit thanks to one card in particular.
Bird is the Word

The current cEDH meta is one of intense interaction. If you have four players all keeping either a five or six card hand, you are looking at something like four to eight pieces of interaction among the table. That means, on average, it’s extremely unlikely that anyone is going to “just win” in the next few turns.
What is much more likely is that everyone is going to play a creature or two that are allowed to resolve and not die on the spot. Many popular commanders fall into this category, and it’s part of the reason that cards like
Tymna The Weaver

At the beginning of each of your postcombat main phases, you may pay X life, where X is the number of opponents that were dealt combat damage this turn. If you do, draw X cards.
Partner (You can have two commanders if both have partner.)
and
Thrasios, Triton Hero

Partner (You can have two commanders if both have partner.)
are so popular. Sure, they give you access to colors, but they also cost very little mana and are generally allowed to exist because they don’t threaten to immediately end a game.
In flies
Francisco, Fowl Marauder

Francisco can't block.
Whenever one or more Pirates you control deal damage to a player, Francisco explores.
Partner (You can have two commanders if both have partner.)
. Look, it can’t block! It has a damage trigger that only works on Pirates, and since it has zero power, it can’t even trigger itself! Surely this creature is allowed to live, and that is why it’s going to see play.
The current “best deck” which has won many different events lately is
Tymna The Weaver

At the beginning of each of your postcombat main phases, you may pay X life, where X is the number of opponents that were dealt combat damage this turn. If you do, draw X cards.
Partner (You can have two commanders if both have partner.)
paired with
Kraum, Ludevic’s Opus

Whenever an opponent casts their second spell each turn, draw a card.
Partner (You can have two commanders if both have partner.)
. So, you can partner Francisco with Kraum for a Grixis deck as just one open option.
Another popular suggestion is Francisco with
Akiri, Line Slinger

Akiri gets +1/+0 for each artifact you control.
Partner (You can have two commanders if both have partner.)
. Because this deck typically runs auras and equipment, it’s quite easy to present both Francisco and Akiri as exceedingly low mana threats that will generate value while pressuring the board. The lack of blue is always a concern, but non-blue decks do show up and can win, especially in a meta where small creatures are allowed to exist.
However, the most likely pairing is Francisco with
Malcolm, Keen Eyed Navigator

Whenever one or more Pirates you control deal damage to your opponents, you create a Treasure token for each opponent dealt damage. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")
Partner (You can have two commanders if both have partner.)
. This team gives you a flying value engine that can easily happen on turn three in 100% of your games. It might not seem like it, but generating a
Treasure



It’s not terribly rare for decks to sneak in cards like
Combat Research

Enchanted creature has "Whenever this creature deals combat damage to a player, draw a card."
As long as enchanted creature is legendary, it gets +1/+1 and has ward {1}. (Whenever enchanted creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays {1}.)
or
Curious Obsession

Enchanted creature gets +1/+1 and has "Whenever this creature deals combat damage to a player, you may draw a card."
At the beginning of your end step, if you didn't attack with a creature this turn, sacrifice this Aura.
when you have a cheap, evasive body that virtually guarantees free card draw. Francisco works extremely well with these cards, and I would be surprised if the bird does not show up in lists that include these cards.
The Magic Word

In a long line of
Silence



Many commonly played cards like
Deflecting Swat

You may choose new targets for target spell or ability.
don’t exactly stop Permission Denied, as the secondary effect still stops all your opponents from casting more non-creature spells anyways. For this reason, you are sure to see this card integrated into many competitive white/blue decks right away.
No More Words

Certainly
Grand Abolisher


This thing is also a Warrior, so it’s an easy include in the very popular
Najeela, the Blade-Blossom

{W}{U}{B}{R}{G}: Untap all attacking creatures. They gain trample, lifelink, and haste until end of turn. After this phase, there is an additional combat phase. Activate only during combat.
. Will it see play outside of Najeela though? Certainly in any deck that already runs Abolisher or
Ranger-Captain of Eos

Sacrifice this creature: Your opponents can't cast noncreature spells this turn.
. Kutzil is a potential add if the secondary effect is relevant at all.

It seems like
Dauntless Dismantler

{X}{X}{W}, Sacrifice this creature: Destroy each artifact with mana value X.
is getting a lot of hype and
Charismatic Conqueror

Whenever an artifact or creature an opponent controls enters untapped, they may tap that permanent. If they don't, you create a 1/1 white Vampire creature token with lifelink.
is getting none. Let me try to sell you on the Vampire just a bit.
Giving your opponent a choice means they can make the wrong one. This works on both artifacts and creatures, so it’s a much wider application. Generating a 1/1 lets you gain value from
Skullclamp

Whenever equipped creature dies, draw two cards.
Equip {1}
,
Ashnod’s Altar

Finally, Dismantler is a virtual three mana, not two, because the main point of the card is blowing up those tapped
Treasure

An Obvious Include

This card is popping up on everyone’s radar and for good reason, it’s solid as heck! What strikes me is that another card existed long before,
Nimble Obstructionist

Flying
Cycling {2}{U} ({2}{U}, Discard this card: Draw a card.)
When you cycle this card, counter target activated or triggered ability you don't control.
, which is comparable. They each have their strengths and weaknesses, but a
Stifle

Well, for starters you get a 3/2 beater on top of the deal, not instead of, as is the case with Obstructionist. Furthermore, one of the best strategies in Commander at large is to keep something in play but useless rather than remove it. Thus,
Tishana’s Tidebinder

When this creature enters, counter up to one target activated or triggered ability. If an ability of an artifact, creature, or planeswalker is countered this way, that permanent loses all abilities for as long as this creature remains on the battlefield. (Mana abilities can't be targeted.)
offers a juicy payoff when it works.
So, that is what it comes down to, a safer piece of interaction or a riskier one with a bigger potential reward. It’s not a stretch to convince a table that letting your Merfolk resolve to stop a
Tymna the Weaver

At the beginning of each of your postcombat main phases, you may pay X life, where X is the number of opponents that were dealt combat damage this turn. If you do, draw X cards.
Partner (You can have two commanders if both have partner.)
from ever going off is the right play.

Kellan, Daring Traveler

The Adventure side is going to be one green mana make three to four
Map


Then, you get a 2/3 for two that can draw you a card when you attack. Of course, you can quite easily stack your deck thanks to your Maps. For sheer value, I think it’s hard to ask for more from a card. Keep in mind that both white and green love token doubling!
A Good Mix
The Lost Caverns of Ixalan has a variety of cards that could see play at all levels and in multiple formats. cEDH has incredibly strict requirements for cards to be even considered “playable,” but event after event proves that the format is more open than it would first appear.
From as recent as Wilds of Eldraine, we are seeing cards like
Talion, the Kindly Lord

As Talion enters, choose a number between 1 and 10.
Whenever an opponent casts a spell with mana value, power, or toughness equal to the chosen number, that player loses 2 life and you draw a card.
make multiple strong appearances and even win an event. The cEDH meta is shifting faster than ever, and new cards are absolutely making an impact.
Don’t only follow the trends, though, try new cards out! Local metas vary widely, and what may make sense at one shop does not work at all elsewhere. As always, if players are reacting to what you are doing, you are doing it right!
