Welcome to our early MTG Arena Sealed Cube Guide. The event isn’t on Arena yet, but based on our experience with regular Sealed and Cube Drafting, we can make an educated guess on how to approach this format.
We’ll explain how Cube Sealed works on Arena and how to build your deck. Let’s get right to it.
Arena Cube Sealed Information
Cube Sealed is just like a regular Sealed with two differences – the event is Phantom and the packs are Cube Packs. You still get six packs and you build your deck with them.
Sealed Cube is a phantom event. That means that you won’t get any of the cards you open. The reason for this is that there are tons of rare and mythic cards in Cube packs. If you would actually got to keep these cards, the cost of Cube Sealed would probably be over 30,000 Gold.
The entry fee will thankfully be much less, even less then regular Sealed.
Which Cards are in Cube Sealed?
The exact list of cards hasn’t been posted yet. However, we do know that Cube will contain cards from all sets on Arena. That includes both Historic Analogies and cards from Brawl events. Who knows, maybe you’ll be able to draft the big frog.
Cost & Prizes
We currently don’t have any definitive information about entry fee and prizes for Sealed Cube. Once it becomes available, we’ll update this article.
As we can see in the latest State of the Game article, prizes will contain a combination of Gold and ICRs (Individual Card Rewards). However if you reach five wins, you’ll get Gems!
Event is similar to the regular Sealed in how long it take to play it. With one entry, you can play until you get three loses or five wins – whichever comes first.
As always with Sealed, you want to build the best possible deck from the cards you opened. This can be hard to do with so many powerful cards in all five colors. That’s why we have a step-by-step guide on how to approach deck building.
How to Build Arena Cube Sealed Deck
1. Check Your Rares / Mythics.
This is the easy part. You already want to see your rares and mythics. In Cube Sealed you’ll have plenty of them – pay attention to the best ones.
2. Check Each Color Separately.
It can be hard to figure which are your best cards, because Arena Sealed Cube contains so many good cards That’s why it’s a good idea to check each color separately.
At this step you’re trying to find out which color has the most good cards. One thing you can do is to arrange them into three groups:
- OP cards – ones that you definitely want in your deck, good on their own.
- Solid cards – ones that make you want to play that color.
- Playables – cards that you’ll play if you will have the deck in this colors.
The first two groups are the most important ones. Try to find two colors that have a lot of cards that fit there. Those might not be the final colors of your deck, but it’s a good start.
Playables are only relevant if you somehow don’t get enough of them in the two colors you picked. If that happens you want to change one color or maybe splash a third one.
3. Explore Your Lands.
You should pay attention to the lands you open. If you have enough dual lands, you might consider splashing a third color. Cube usually has good lands and better mana base.
That’s why you shouldn’t splash the same way as in regular Sealed. For example, you’re playing black-white and want to splash green. Something like 7 Plains, 7 Swamps and 3 Forests is usually considered an okay mana base. However in a Cube environment, this is pretty mediocre at best. Try to have at least two dual lands in a three color deck.
4. Build More Decks.
So now you know which colors are best and how many of them you can play. The most common mistake at this step is to build one good enough deck and immediately start playing. If you want to win more games, this isn’t the correct approach.
What you want to do is to build at least three different decks. This way you might find a better deck.
5. Tune the Best One
Once you’ve chosen your optimal deck, check all cards in the colors again, don’t forget to check artifacts and hybrid cards like Kaya, Bane of the Dead. You can play it in green-white deck for example.
Carefully consider your worst card in the deck and compare it to the best card that’s left in your pool. Should you maybe swap them?
When you’re done with all of this, check if you have a correct land ratio given the cards you’re playing. Arena usually does this for you, but the algorithm isn’t perfect. If you have many triple colored cards like Ayara, First of Locthwain, you should play more lands of the respective color.
That’s it. You should now have a pretty good deck. However, don’t forget to change it between games if it doesn’t work.
This section will be updated once we get full cards list for the cube. For now, we have a couple of tips for you:
- Don’t panic when your opponent plays a good rare. The power level of the Cube is higher that the one of a regular set, so both you and your opponent will have plenty of bombs.
- Pay attention to what your opponents are doing. Does it look like they should’ve blocked, but didn’t? There’s probably a reason for that. The creature which didn’t block might be very important to their game plan. Consider destroying it if possible.
