With Mythic Championship VI around the corner, rather than go through a draft like I usually do, I want to outline the key features of Throne of Eldraine Draft. My opinions of the format aren't necessarily correct, but it's a good starting point for watching and understanding some of the best players in the world navigate a Draft!
The Format is Balanced
I've heard so many opinions from white is unplayable, to green is bad, to black is the best color, to blue is so overpowered that the format is atrocious, to mill is the best deck, to mill is the worst deck… I can go on.
Basically, Magic players love hyperbole.
This format is just balanced, and this isn't something we are used to. Every single color and color combination is viable. I've had the least success with Orzhov and Simic, and the most success in mono-color decks, but I don't believe anything is much better than the rest. This doesn't mean that every color and archetype are equally balanced, but that the power-delta between archetypes is small.
Draft The Hard Way
This is going to sound obvious, but I think it's important to emphasize. I'm of the school of thought where there are plenty of reasons to bias towards and/or force a subset of archetypes rather than staying open. That's a whole article topic in itself, but I want to mention that, in Throne of Eldraine, I would not advise this without a substantial read on the table or environment. Given the density of good archetypes given the format-balance, staying open pays dividends. I put much higher stock in sending and receiving signals in this format and try my best to discover the open lane. Even if it's an archetype I'm less familiar with or think isn't as good, it's better to be in the open lane.
Please Play White Cards
Okay, maybe this is beating a dead horse since the last two points are about a balanced format, but I think it's important to mention.
White hasn't been great the last few sets, and it seems that the world refuses to adjust. Flutterfox and Silverflame Squire continually wheel on Magic Online. They should not. White should not be this open. In fact, it's to the point where I do think it's reasonable to bias towards white. My previous statement that "I would not advise [forcing] without a substantial read on the table" means that, while I believe the format is balanced, I also believe that white is underdrafted enough online that it is correct to begin the draft with a bias towards white. For more context on this scenario, check out Ethan Saks' article on the topic.
The Format Is Faster Than You Think
While everything is viable, I bias towards aggressive decks. Rosethorn Halberd is the key to green-aggro, which I believe is the best way to build green decks. I have Rimrock Knight as the second best red common, only marginally ahead of Searing Barrage. And the white decks all lean aggressive. Dimir, Izzet, and Mono-Blue are the only archetypes that cannot be built aggressively. Golgari Food and many other archetypes are still solid as midrange and controlling decks, however I just prefer the aggressive counterparts.
The key is the Adventure mechanic. Take Silverflame Squire and Garenbrig Carver higher. They aren't super-high picks but having cards that can play like Briarhorn is a huge upside in Limited. It means that the aggressive decks in this format, unlike any other Limited format, have access to a good amount of card advantage. In most formats, when the game doesn't end early, aggressive decks get buried. While it's still not trivial to win games that extend for a while with an aggressive deck, it's easier in Throne of Eldraine thanks to the adventure mechanic.
Optimize For A Good Manabase
The most important feature of Throne of Eldraine Draft is the need for a good manabase. 9-8 just doesn't cut it. If your deck does not have a clear main color, it's likely that there was a better way to draft your seat. This isn't guaranteed, but I find that there isn't time to stumble and there are too many cards with high color requirements. The heuristic I use is that I want at least eleven sources of my main color when my deck is above a 7/10.
Adjust Your Pick Order For Combos
There are a variety of two-card-combos at low rarity in Throne of Eldraine. Lucky Clover alongside Adventures, especially on curve with Reaper of Night, but even also late-game with cards like Shepherd of the Flock and Merfolk Secretkeeper. Witch's Oven and Cauldron Familiar is also a combination of cards many decks struggle to beat. There are so many build-around cards that it isn't difficult to optimize for them. An example of "adjust your pick order for combos" is that you should probably take Opt higher. It helps piece these combos together for very minimal investment, and also provides synergy for the Izzet deck!
