Magic The Gathering: Arena Dev Tracker

It's clear there's a lot of interest in how the prices work, so here's a general overview. 

Decks start off with a base price, which is basically the same price it would cost to craft the deck with wildcards. This is what's listed with the slash, but it gets discounted a couple times.

First off, each deck gets discounted by a variable rate, based on the type of deck. Foundation decks, which are designed to be a starting place for newer players, are discounted more than Champion decks, which are based on popular and successful decks in the meta.

Next, each deck gets prorated down based on the cards you already have in your collection. Note that the proration happens after the discount, which means the price reduction you'll see from crafting any given card will vary from deck to deck.

This means that the prices for any given player will vary a good bit, based on your collection. In OP's screenshot, decks look to vary between 30% and 90% off the ba...

No, there’s no deck weight in any ranked queue

In ranked queues you will continue to be matched against a bunch of meta decks, yes. As many express in this thread, for some that's part of the challenge and fun of brewing.

In the unranked queues (like Standard Play or Brawl), we'll try to pair you with deck of similar strength, so you should see a lot less of the meta decks. The system isn't perfect (turns out it's not easy for a computer to judge the power level of a decklist), but that's the goal. I'm obviously biased, but I spend a good bit of time in Historic Play with silly decks that make me smile, and I feel like I get to have good fun with them.

Yup, the Alchemy draft will add the Alchemy cards as an extra slot. We like the way this plays and don't have any plans to change it.

Sorry you're having this experience! We are aware that a small number of winners are running into issues like this, and we are actively working with the different groups involved to resolve them. This is being worked on, and it hasn't been forgotten. It's just taking longer than any of us would like.

Agreed; we treat memory issues like this as a kinda-digital-only mechanic.

Yeah, the little pop-up that says "Undo" works like a button (as well as being an indicator that you can undo). You can also click it on PC, in case your Z key is broken or something

We agree! Alchemy is designed to have a metagame with more change and flux, and having a set legal for 5 years runs counter to that. Foundations will be legal in Alchemy, but it will rotate out in the normal two years, alongside BLB, DSK, etc.

The only winning move with references is not to play ;)

I've played against these random bots, and there's nothing nice about those games. Even when you know that it's random, it's still disorienting, like trying to have a conversation with someone who replies with random words.

Yes, that will get picked up as well

I'd like to give a shoutout to Underworld Breach. It had two classes of major problems due to being the first card to confer a non-mana cost to arbitrary cards.

Firstly, it made payment and affordability checks much more complicated. If you have something like Tormenting Voice, you can discard a card for the additional cost before exiling it from your graveyard. We don't let you choose payment order on Arena, so we had to change things to get the order to be smart here. For affordability, we had to predict how the costs could interact in terms of payment resources.

The other major category was linked ability bugs. Cards exiled to pay the escape cost were incorrectly linking to text like "the exiled card" due to us not yet having a good signal that the escape cost wasn't "native" to the card. We played whack-a-mole with bugs in this space for months before getting a more general solution that seems to work for all current MTG behavior (fingers crossed!). #wotc_staff...

The issue there was that the Evoke action was incorrectly taking credit both for being an alternative cost (correct) AND for being the permission source of the action (wrong, Muldrotha is). So when deciding whether to use up part of Muldrotha's permission, the action isn't marked as relevant. The fix was a one line change to have the Evoke action copy over the permission source from the action it was duplicating instead of overwriting it. Definitely the sort of typical human error Alex alludes to. #wotc_staff

We do look at player reports when deciding which accounts get suspended/banned for roping, but we also have pretty comprehensive gameplay data to let us identify which players are being problematic here as well. So, you can report people if it makes you feel better, and it does help. But don't feel like you have to.

Unknown Shores (and mana filtering in general) is kind of a pain in the butt for Autotap too, so having it in RoboQA games helps stress test Autotap's performance and internal assertions about its correctness too. #wotc_staff

Excuse me! That scorpion is Pinchy McStingbutt, triumphantly returning to Arena after a long journey.

We released an update this morning that should have addressed this problem. Let me know if you're still having issues

Thanks for the report; we're aware of this bug affecting Bo3 games on mobile, and we are working to ship a fix very soon. You should still be getting rewards and rank progress on the back end, but your client is hanging when it's trying to display that
