MTG Arena is my favorite way to play Magic, and it brought me back to the game in a big way. I’m a casual free-to-play player, so my card and deck building options are limited. I always look online for new decks, and if there’s anything on the market that can help me build new and competitive Standard or Pioneer decks or update my old decks that aren't winning that much, it's Draftsim’s Arena Tutor.

Today I'll show you five reasons why you should use Arena Tutor’s deck builder to craft decks on MTG Arena. Stay with me and we’ll go through a little tutorial together to make the most of this awesome resource!

Why Arena Tutor Is the Best Free MTGA Deck Builder

Reason #1: Gives Me Hundreds of Ideas

I have 20 rare wildcards and 10 mythic rare wildcards to spend, so it’s time to build a new deck. In the Arena Tutor Metagame section, you can see Arena's formats and top decks within them. Or, you can search by the least amount of wildcards you’ll need to spend. If you’re a mono-red player, you can see which mono-red builds do well just by looking for mono-red decks.

Reason #2: Metagame Is Updated Twice a Week

I make some terrible decks, so I usually look on the web to see the new tech. Do control decks play new win conditions now? Did some new deck become top tier overnight? If you don't want to join in, you can still scout the competition to see which key cards to disrupt. Arena Tutor updates the metagame automatically, so your main concern is to play MTG with a nice deck. Of course, you still need to get the cards on Arena to build them.

Reason #3: Free Win Percentage Data

Arena Tutor hands out the win percentage of decks on a plate natively on the platform. You can consult Arena Tutor to see which decks perform better in which formats.

Reason #4: Easy to Use

How often have I gazed upon a nice and shiny new deck, only to discover that I can’t build it on Arena? Or that it sucks? Netdecking is so easy with Arena Tutor. I can look up decks by color, color pair, formats, and win percentage. It’s actually integrated into my MTG Arena account, so Arena Tutor already tells me what deck I could play based on my current collection.

Reason #5: It’s Free

Look, there’s a premium version of Arena Tutor and you should definitely try it because it adds a bunch of nice features, but not in the deck builder. All the resources I show you in the deck builder feature are 100% free, including previews of sample hands.

Building Decks Using Arena Tutor

Enough talk! I’ll show you Arena Tutor from my personal PC using data from my MTG Arena collection. First, let’s open Arena Tutor. Here’s the initial screen, including the essential Metagame tab, which allows you to see the top decks you’ll want to build. So, let’s click on it.

Here I can select the format from which I want to peruse decks, and the criteria. For example:

• By Win Rate: Shows the decks with higher win rate percentages.
• By Popularity: Shows the most played decks in the format, regardless of win rate.
• By Completion: Shows the decks that you can build with your collection using the least number of wildcards.
• By Name: If you’re looking for a specific deck in alphabetical order.

Of course, I can do that in all legal Constructed formats on MTG Arena. I’ve just selected by completion and the Standard format. Let’s look at that Jeskai () Control, which I can build with my current cards and wildcards.

Standard Jeskai Control Deck

The yellow box in the top right corner shows which wildcards I’ll need, and confirms that I can build this deck, thanks to Arena Tutor’s collection tracker. The yellow arrows show which cards I need to craft; I have two copies of Elspeth, Storm Slayer and the deck needs three, so I’m one short (the orange 1 indicates that). Fountainport is the same: I need two more copies. And so on.

Finally, the orange box highlights the export deck function, which I’ll use to send this to MTG Arena.

In the deck section on MTG Arena, just click import.

Here’s our nice Jeskai Control deck in Standard. I’ve changed the deck name, so now I just need to click on craft all, and I’m done! A new Standard deck is ready to go!

Selesnya Rabbits Deck in Alchemy

Let’s change formats. I’ve returned to Arena Tutor’s metagame tab, and now I’ve selected the Alchemy format, but by popularity this time. Selesnya () Rabbits is the most popular deck, with a 23% share of the meta. You can also see the wildcards I need, and in the righthand corner, I’ve highlighted the Selesnya Rabbits deck, which also has a good win rate. It’s a popular metagame choice and puts up good results, so it's a great contender for my wildcards.

Analyzing this deck, I’ll need a bunch of rare and mythic rabbits and some good uncommon ones (really not the problem). But those two Warren Warleaders will tax my mythic wildcards. Buxton, Decorated Host is powerful, but it’s only legal in Alchemy and Historic, so I need to consider that, too.

Let’s export it via Arena Tutor and import it into MTG Arena.

Now I have a problem: As most of you MTG Arena users already know, the deck is imported to the bottom of the deck section because I don’t have enough wildcards to build this deck. This deck requires three mythics, and I only have two. The rares and uncommons are okay. Maybe I could replace a Warren Warleader with another rare or mythic I already have. Or I’ll just play some Bloomburrow drafts since most cards I need are from that set.

Sultai Frogs Deck in Historic

Let’s select a deck by win rate this time, in the Historic format. I’m not nearly close enough to complete a Boros () Auras deck, so I'm taking a look at the Sultai () Frogs deck next.

I don’t have the necessary wildcards, and I require three Cavern of Souls to build this deck. Maybe I can craft one of these with a mythic wildcard, add another two lands for mana fixing, and call it a day. I can easily craft the other cards with my remaining wildcards. Regardless, I have to export the deck, import it into Arena, and there I’ll decide which cards to craft and which ones to replace.

Does MTG Arena Have an Auto Deck Builder?

There's no automatic deck builder on MTG Arena. MTGA does have a deck builder and a feature to import the decklists you see online (netdecking), provided that the websites have the “Import deck to MTG Arena” feature, but that’s it. When you add Arena Tutor, you’re playing with power. You’ll get the updated metagame for the format you want to play (be it Standard, Pioneer, Historic or Timeless). You’ll be able to see how many wildcards you need to build the deck, and make sure you never see Arena's “Invalid Deck” error!

That’s all from me on Arena Tutor and how effortlessly it can “netdeck” competitive Constructed decks.

I'm mainly an MTG Arena player, and I can’t recommend Arena Tutor enough. The deck builder is awesome, and the other features are also a must. I can track my collection to see the sets with the highest completion rate, Arena Tutor helps me draft better and build better decks, and it tells me which of my decks have the best win rate. It’s free and very easy to use, so be sure to give it a spin!
