Sultai is back on the menu in Standard. After Uro, Titan of Nature's Wrath was banned from the format, Sultai went from the top deck to barely existing. That has all changed though, with the addition of Kaldheim. There are even two different competitive variants!

Today I'm going to talk about what makes the deck tick, and why it has been able to ascend to the top of the format. 

Sultai Ultimatum

I'm going to start by talking about the version with Emergent Ultimatum.

Whichever Sultai list you do end up playing, it should incorporate Yorion, Sky Nomad. This companion is too good and too powerful to not play. There are additional copies in the maindeck as well, since flickering permanents is going to be a priority.

The Game Plan

The deck plays a variety of removal spells to help shore up its defenses against early aggression. Without those early removal spells you would be very vulnerable to an early creature assault. Whenever your opponent leaves you an opening, put a permanent into play like Llanowar Visionary or Path to the World Tree. Cards with enters-the-battlefield effects will help you get ahead on resources as the game progresses, and they have utility at most stages of the game. Anything that sits on the battlefield and can be blinked later with a Yorion, Sky Nomad is valuable.

As we progress into the midgame and later stages of the game, our cards look a lot more threatening. This deck plays three copies of The World Tree, which means that we can gain access to whatever colors we would like. This means having the ability to cast Tibalt, Cosmic Impostor, or activating Path to the World Tree. Seven mana is kind of the sweet spot for this deck, as we can also cast Emergent Ultimatum.

The deck is built to have lots of strong options to grab with Ultimatum. Unfortunately, the more multicolored cards you add, the fewer targets you have for Ultimatum. The key to building a successful Emergent Ultimatum deck is managing which monocolored cards to play. Alrund's Epiphany is usually a must-grab, as your opponent is rarely going to want to give you another turn.

This deck wins the game by having more resources than the opponent, as most control decks do. The Ultimatum itself isn't game winning, but getting to cast two cards out of your deck is normally worth the seven-mana investment.

I would, however, make a few changes to this list in order to really prioritize making Emergent Ultimatum as good as it can be.

My Version

If you like the idea of making Emergent Ultimatum a focal point in your deck, I think the deck wants a couple more monocolored cards it can grab. Vorinclex, Monstrous Raider is great, and Alrund's Epiphany is an automatic inclusion, but what other options are there? Even a card like Sea Gate Restoration, that replaces a land, is quite relevant with Emergent Ultimatum. This is the type of low-cost addition that definitely makes a difference. The same can be said of Bala Ged Recovery.

This is my take:

It's possible I'll end up making more changes to the sideboard and manabase, but I wanted to highlight some additional ways to improve the Emergent Ultimatum package, and I believe this list accomplishes that. Adding singleton monocolored cards to the list can be relatively low cost, while having a really nice upside. Once you make the changes to make Emergent Ultimatum better, adding the fourth copy makes sense. I will say the one downside to these changes though is you have even more seven-mana plays than before.

Sultai Control (No Ultimatum)

While the Ultimatum package is the most fun way to play Sultai, the old-school version without Ultimatum is the most popular, and perhaps the better direction to go in. The deck is similar to the Dimir Control decks we saw last season, but adding Binding the Old Gods is by itself enough of a reason to have the green. Binding the Old Gods is such an amazing saga to have access to.

This undefeated list from a recent Standard league on MTGO is one that I like a lot. This is much more of a land-go style deck, where you wait for the opponent to play something, and then react to that.

The Game Plan

The idea is the late game belongs to our deck, so the longer the game goes, the more time we have to set up. There is no rush, so the key is managing your mana.

Finding the right time to deploy cards like Mazemind Tome and Binding the Old Gods is definitely important, though there will be times it makes sense to hold up countermagic or threaten to cycle Shark Typhoon. There are big threats that can win the game on their own, like Koma, Cosmos Serpent, and Ugin, the Spirit Dragon.

This deck still makes terrific use of Yorion, Sky Nomad shenanigans. Even if there aren't as many cards you want to flicker compared to the Ultimatum build, there's still Omen of the Sea and Binding the Old Gods. The thing about Yorion is even if you are only flickering one thing with it, that's good enough—the card is still unbelievably strong.

For true control players this is definitely the direction to go in. A nice mix of removal and countermagic, coupled with high-powered threats and card advantage is exactly what you want. Don't worry about having enough tools to win the game, there is plenty here to get the job done.

Building Sultai's Sideboard

Having access to escape cards is going to really help against Rogues. Remember that they need to get through 20 more cards to mill you out. This definitely comes up, and even if there are only a couple escape cards in the deck, you will have time to mill them and escape them. I'm not sure if I like Glimpse of Freedom more than Cling to Dust. Cling to Dust has extra utility against opposing escape cards, so I lean toward that.

It seems like every Standard deck these days has a few obligatory slots for escape cards. After that, because we are a blue control deck, Mystical Dispute is another clear inclusion. In decks like this there will always be matchups where we want less removal, like the mirror for instance, and more controlling cards, like counters. Duress also comes in for similar matchups as a form of cheap interaction.

On the flip side, Extinction Event and Shadows' Verdict are very important against creature decks. I'm a bit surprised Thommimp didn't include Extinction Event in the maindeck, but the format isn't super aggressive at the moment, so this could make sense as a metagame call.

The Ultimatum list has a similar sideboard plan to the more controlling list. Since it has sweepers in the maindeck though, the Ultimatum deck can afford Elder Gargaroth in the sideboard, which can be a great card against decks like Gruul. Countermagic doesn't work as well with Ultimatum, since that deck is more of a tap-out strategy.

Wrapping Up

It's clear that Binding the Old Gods is the single card that has allowed Sultai to take off as a deck once more.

Binding the Old Gods plays so well with Yorion, Sky Nomad that this seems like the perfect home for the card, and the versatility it adds in terms of removal means it will be good no matter what the matchup is. While Binding the Old Gods is the most significant addition from Kaldheim, the Pathways, Vorinclex, Monstrous Raider, Esika, God of the Tree, Valki, God of Lies, Path to the World Tree, Koma, Cosmos Serpent, Alrund's Epiphany, and Saw It Coming are also important options that Sultai now has access to.

Sultai has risen through the ranks to become a top-tier control deck again, so watch out!
