It's Magic time!

Core Set 2021 is knocking on the door, and it's one of the most stuffed-with-goodness core sets of all time. Whether you're kicking off your Magic journey, coming back to the game, or currently a stalwart player, you'll find plenty of cards worth playing.

With powerful reprints like Ugin, the Spirit Dragon to new takes on old friends like Barrin, Tolarian Archmage, or even just adorable pets like Pack Leader (hello, Dogs!), Core Set 2021 is a head-turner.

So, what's the best way to check it out?

The Prerelease of course!

The Prerelease is your first chance at getting your hands on the new cards. What can you expect, and how can you participate?

If you'd prefer watching to reading, you can find me walking through a lot of this in video form here:

Let's run through it today!

Getting to the Core

Prereleases have always been my favorite Magic events of the year.

Prereleases are events where it's your first chance to try out the new set—and to me, the heart and soul of the Prerelease experience is the energy of getting those cards and playing with them. And even if you're just doing that at home, you'll still be doing it with so many other people around the world as a part of the global experience and conversation. Thanks to the internet, we're all connected!

The Prerelease of a set is great because the set is totally new, the footing is fairly equal as everybody plays with the set for the very first time, and you just get to relax and have fun exploring the new cards. It's a lot of fun for old and new players alike!

If you're a Sealed Deck veteran, you may want to skip ahead to the next section, where I talk about what you can expect for Core Set 2021. But if you're new to the world of Sealed Deck, or are maybe just looking for a few extra pointers, read on!

All right. So, let's go over perhaps the most important part: finding product for your Prerelease! After all, you can't very well play if you don't know where to get the supplies you need.

Well, you'll need to get in touch with a store. If you don't already have a local shop you frequent, be sure to check out the store locator to find one near you! That store may even offer preregistration. Prereleases are some of the most popular events we put on, so be sure to check and see if the store preregisters. Be sure to plan ahead.

While most Prereleases are run as an in-store event, because of the COVID-19 virus, as a special exception, players can pick up Prerelease packs and take them home! In fact, we recommend it. In different areas of the world, different rules and restrictions may apply to what can be open—so please take appropriate precautions, be aware of government-level requests, and do only what you feel comfortable with.

And if you're not able to get to a local store for any reason, you can still play on Magic: The Gathering Arena! (And if you're still learning, even better, as MTG Arena is excellent for new players!) They have Sealed events starting June 25, and the play experience is still the same, great Magic. It's a great time to try out MTG Arena if you haven't already.

Okay now, let's see. You have a store selected, and you've taken a look at all the awesome cards in the Core Set 2021 Card Image Gallery.

You're all set! Now it's time to actually open up some of those cards!

Core Considerations

Okay. So, let's say you've ended up with a Prerelease pack in your hands. What can you expect to get?

Your box will look like this:


Inside, you'll get six Core Set 2021 boosters. . .plus, a random stamped rare or mythic rare card as your Prerelease foil that could be any rare or mythic rare in the set!

Then, of course, you'll get a couple other goodies—like a spindown life counter to keep track of your life total. Actually, you know what? Let's just crack one open and take a look!

Everything you get inside

Excellent! Plenty of great stuff here.

And, of course, front and center are those booster packs. Let's talk about what to do with those next!

First things first: crack open those booster packs! Then, you'll have a stack of cards.

So. . .what now?

It's time to build your deck, of course!

Sealed Deck is a little different from normal deck building. You get to build a deck using only the cards in front of you, plus as many basic lands as you'd like. Also, unlike a normal Constructed deck where the minimum deck size is 60, you only have to play 40 cards.

The first thing you're going to want to do is figure out a method to pick which colors you'll be playing. I recommend playing two colors. You can sometimes "splash" for a third color, but generally you'll want to pick two to be your core.

Some things that may draw you into specific colors are:

  • A really strong rare you're excited about
  • Plenty of "removal" cards that can deal with your opponent's creatures
  • A lot of playable cards in that color
  • A good "mana curve" in that color—meaning lots of creatures of different costs

Ideally, the colors you pick will have all four, but if two or three of those are true, that's plenty good.

Now you have your colors down. From there, how do you take everything you have and figure out which 22–23 cards you're going to want to put in your deck?

Here's one process that may help!

First, lay your creatures out in mana-cost order. This helps you see what creatures you're going to potentially be able to cast at each part of the game. (Don't lay your noncreatures out at this point unless they're cards you are planning to play as soon as you have that much mana—for example, you will generally cast a Quirion Dryad on turn two, whereas Heroic Intervention isn't usually a turn-two play.)

A good "mana curve" of creatures is crucial to a successful Sealed deck. You don't want to have a ton of cards at any single spot in the curve. It's important for you to have a good mix so that you can play your cheap spells in the early game and your expensive spells in the late game. As a very general rule for Limited, I would look to play something like this:

  • 1 mana: 0–2
  • 2 mana: 4–6
  • 3 mana: 3–5
  • 4 mana: 2–4
  • 5 mana 1–3
  • 6+ mana: 0–2

mana curve

That's far from hard and fast, but it's a good place to start. Cull your creatures down to these numbers by choosing your favorites.

Now that you have your core (pun intended) creature base figured out, it's time to add in spells! Pick your favorites among your colors to bring your deck to 22 or 23 cards, and then you're good to go from the spell side.

The spells you're going to want the most are what are called "removal spells"—these are the spells that permanently neutralize your opponent's creatures by either dealing damage, keeping them tapped, or just straight-up destroying them. Sealed Deck Magic is all about creatures, so you'll want to play most of the cards in your colors that can get rid of your opponent's creatures.

Interested in more tips? Here are a few more things to keep in mind for deck building:

  • You can play more than 40 cards, but you really should stick to 40 if possible. Every card you play past 40 just means it's that much less likely you're going to draw that awesome rare you put in your deck!
  • The land ratio you're looking at should be about 17 lands to 23 nonlands. This isn't right 100% of the time, but most Limited decks end up looking like this, and, in general, it's what I would want to have.
  • Play a mix of cheap-to-cast and expensive-to-cast cards. If you have all cheap, small creatures, then a single big creature can shut you down. If you have all large, expensive creatures, you risk getting run over first. Stick to a mix that focuses on the two-, three-, four-, and five-casting-cost creatures. More games of Sealed Deck are won by casting a creature every turn starting on turn two or three than any other way.
  • Evasion is important! Often, Sealed Deck games will get into stalls where both players have a lot of creatures and neither player can attack very well. Creatures with abilities like flying ensure that you can break through these creature stalls.
  • Unlike most Magic formats, sealed tends to be a little slower. If your deck is on the slow side, choosing to draw (go second) rather than play (go first) can be reasonable to give you that extra card.

But Wait, There's Core

Starting with Throne of Eldraine, we debuted our new "booster fun" initiative, putting alternate, tricked-out versions of specific cards into packs. And with Core Set 2021, we're bringing that up a notch and putting it all around the set!

You can find that in a few different ways. First of all, the set's main planeswalkers and their associated cards at lower rarities have alternate versions with a special frame for that character.

Chandra's MagmuttChandra, Heart of FireLiliana's Standard Bearer

Each planeswalker's card lineage has its own frame and look!

Additionally, six cards have been handpicked as gorgeous borderless cards, with alternate art to boot!

CultivateSolemn Simulacrum

What's more, the planeswalkers in the set can also be opened in a special borderless version:

Ugin, the Spirit DragonTeferi, Master of Time

They're really spectacular. Either way, you can find these in booster packs. Plus, the extended-art cards continue in the Collector Boosters! They'll look like this:

Subira, Tulzidi CaravannerPack Leader

Magic from a Distance

Depending on where in the world you are, playing Magic in a store may be a problem right now due to COVID-19. So, if you get product to bring home and aren't able to play in a store, what should you do?

Well, of course there's Magic: The Gathering Arena and Magic Online, which let you play the set from a safe distance. But one other thing you could try is playing over a phone or a webcam!

Growing up, me and a friend would play Magic over phone calls. As you can imagine, that was a hassle: trying to remember all the cards was a nightmare, and it would be even harder for a Prerelease!

But now we live in a much different age—an age where webcams are readily available, everywhere from laptops to even your cell phone!

Depending on the setup you and your friends have, there are many ways to do this. Check out my article on playing Magic over Webcam for all kinds of tips on setting it up—and with places like Discord, Google Hangouts, and, it's easier than ever to get a webcam game going.

Core Takeaways

While you're at your store to pick up Prerelease packs, you can also buy other things—like booster boxes! Be sure to call ahead to preorder one, and while supplies last, you should be able to pick one up.

And as a fun extra bonus, in addition to the Buy-a-Box card, if you buy a box, you'll also receive two Jumpstart boosters as well! (While supplies last.)

Rin and Seri, Inseparable

JMP Boosters

This will give you a fun little taste of Jumpstart. (For more information on what that is, click here!)
