Phyrexia: All Will Be One Mechanics on MTG Arena

For more information, please refer to the main Phyrexia: All Will Be One Mechanics article.

Toxic and Poison Counters

Toxic badge
A player dealt combat damage by a creature with toxic also gets poison counters equal to that creature's total toxic value.

Creatures with toxic will have a badge that also indicates their toxic value—how many poison counters are given to that player when dealt combat damage—to ensure that information remains top level.

Toxic 1

It's important to remember that toxic causes an additional effect! Creatures with toxic deal combat damage and give poison counters to players, and a creature's toxic value and its power aren't necessarily connected.

Toxic 2

Give +1/+1 to creature with toxic 1? Its toxic value will (still) be 1. There are also some specificities to toxic, such as only applying to players being dealt combat damage, but you can always mouseover (or tap on mobile) the card reminder text!


Corrupted is a new ability word that highlights abilities that care whether an opponent has three or more poison counters. On MTG Arena, cards with corrupted have a badge that both represents the ability word and keeps track of the necessary poison counters an opponent must have for corrupted abilities to be utilized.

Corrupted 1

As your opponent gains poison counters, the badge on cards in hand and on the battlefield will update to reflect their current corrupted state, cumulating in three appropriately toxic-green poison counters.

Corrupted 2


Proliferate badge
Choose any number of permanents and/or players, then give each another counter of each kind they already have.

When you proliferate on MTG Arena, the game will automatically select targets based on the type of counters you have and will prompt you to confirm the selection before submitting. For example, it will automatically choose to proliferate your opponents poison counters and oil counters on permanents you control but not your poison counters.

Proliferate 1

If a player or permanent has more than one kind of counter, please note in the reminder text that proliferate gives another of each kind they already have—you can't have it get just one kind of counter it already has and not the others.

Additional Notes

  • The display of compleated planeswalkers on the stack has changed to account for the player paying life. For example, casting Jace, the Perfect Mind for 2U and 2 life results in him showing 3 loyalty on the stack, instead of 5.
  • Be careful when dealing damage to Phyrexian Obliterator and Phyrexian Vindicator! MTG Arena will prompt for manual combat damage assignment if there are multiple legal ways to assign damage—don't assume the default assignment is what you want!

Other Improvements and Features

In addition to the card set, we want to highlight a few noteworthy changes, improvements, and bug fixes players should expect on February 7:

  • Music to Your Ears – You can once again listen to other audio while playing on iOS mobile devices!
  • Waste Not, Want Not – There are several bug fixes related to how the deck builder handles Wastes, most notably players will be able to save colorless Historic Brawl decks using Wastes and to change the number of Wastes in your deck while using the Suggest Lands feature.
  • Color Coordination – The mana pips shown on deck boxes now handle colorless decks properly and should do a better job of matching the colors your deck actually uses when considering things like hybrid cards, multicolor lands, etc.
  • You Must Be New Here – The event blade will now highlight when new events are added.

Full patch notes will be available once maintenance is complete.
