On October 14, 2022, three months before the release of Phyrexia: All Will Be One and even before the start of the spoiler season of the previous set, several Showcase cards from ONE were shown off on Reddit.[8] These revealed the step-and-compleat foil treatment and several mechanics. A week before previews started, almost all rares from the set were found packaged in Dominaria Remastered packs and subsequently spoiled on Reddit.[9]
Storyline
This is the third part of the four-set Phyrexian story arc where the fate of Dominaria — and the Multiverse — is set to unravel. The Phyrexians grow ever stronger, as Elesh Norn inches closer to her plan to conquer the Multiverse.[10] We view Phyrexia from their point of view. They are antagonistic with each other.[11] The Planeswalkers who gathered to stop the Phyrexians on Dominaria lost — badly. Now, every plane of the Multiverse is in Phyrexian sights with their plan to invade them all. The only hope that remains is to take them out on their home turf, destroying the Phyrexian's meansto Multiverse invasion. The risk that some of the heroes fall to Phyrexians is high, but the stakes for everyone else are even higher. Planeswalkers team up and head down into New Phyrexia to end the threat of invasion once and for all.
Five of the ten planeswalkers printed in the set are compleated, a disastrous casualty rate in preparation for the finale. The cards that represent the Story Spotlights in Phyrexia: All Will Be One are:
2/2 Drone artifact creature with deathtouch and “When this creature leaves the battlefield, each opponent loses 2 life and you gain 2 life.”, for Kaito, Dancing Shadow.
Poison counter marker.Available only in Draft and Set Boosters
For the Japanese market, six additional tokens with alternate art became available.[16]
Poison counter
Poison counter spin-down
Stores in Germany, Austria, France, and Italy can participate in a special Magic: The Gathering play and purchase promotion. Players who participate in a Magic: The Gathering event, and purchase €75 of Phyrexia: All Will Be One sealed product receive a poison counter. The poison counters are green 10-sided dice with a Phyrexian symbol in place of the number ten.[17]
Phyrexia: All Will Be One sees the return of Poison counters and the Phyrexian-flavored Proliferate mechanic.[8] To give a different proliferation gameplay experience to the -1/-1 counters from Scars of Mirrodin block and the +1/+1 counters in War of the Spark, neither of these counters are present, and instead oil counters are used. This would be the first set since the simplified Portal sets to not use stat-changing counters and is the only premier set or equivalent to not have any.
The new Toxic mechanic is a reworking of Poisonous. Instead of giving poison counter as a triggered ability, this is more like Lifelink adding the counters instantaneously (Players dealt combat damage by this creature also get N poison counters).[15]
The Corruptedability word is also new.[8] Corrupted is a Threshold variant for abilities that can only be activated or triggered if an opponent has three or more poison counters.[8]
A keyword ability on equipment is For Mirrodin! (When this Equipment enters the battlefield, create a 2/2 red Rebel creature token, then attach this to it). This is similar to Living weapon.
Planeswalkers are featured in both Mythic Rare and Rare, with ten total in the set.
Rebel is seen for the first time as a creature type since the Time Spiral block. Four cards with the type represent the small number of Mirran survivors (although Equipment cards with the For Mirrodin! keyword create them as well.) On the other hand, more than 120 cards have the Phyrexian creature type.
Each of these raresorceries has a mana cost of XM or XMM, with an additional effect if X is 5 or more, and depicts a monument for an associated praetor.
Each of these Legendary Phyrexian Horrors costs XMM and represents a Dominus of New Phyrexia, living monuments to the ideologies of each Praetor. Each has a first ability that doubles an effect, and a second ability that costs two phyrexian mana to place an indestructible counter on them.
Each of these common artifacts can be sacrificed for at instant speed or with an on-color effect for M at sorcery speed, both effects drawing a card. Each is named for the realms of each praetor and vaguely resembles the head of each of them.
Ten uncommon dual-colored cards, each a signpost for a draft archetype.
Mega-mega cycles
For each of the visits to Mirrodin in Fifth Dawn, Mirrodin Besieged, and Phyrexia: All Will Be One, a cycle of instants or sorceries has been printed that depict the suns at their dawn, peak, and setting, with a mechanical link to the next cycle. All Will Be One printed the Twilight cycle, showing the "end" of Mirrodin, all of which are X spells like the Zenith cycle from Mirrodin Besieged.
Additionally, the Skullbomb cycle finishes the trio of Spellbomb designs from Mirrodin and Scars of Mirrodin: both modes draw a card, with a colored mode doing more with a greater cost.
Blightbelly Rat has two versions — the regular version and the step-and-compleat foil version found in Collector Boosters — that have two different rarities (Common and Uncommon, respectively).[24]
2/2 Cat creature for Kemba, Kha Enduring.
1/1 Phyrexian Goblin creature for Charforger, Chimney Rabble, Churning Reservoir, Gleeful Demolition and Ovika, Enigma Goliath.
3/3 Phyrexian Beast creature with toxic 1, for Goliath Hatchery, Lukka, Bound to Ruin and Viral Spawning.
2/2 Drone artifact creature with deathtouch and “When this creature leaves the battlefield, each opponent loses 2 life and you gain 2 life.”, for Kaito, Dancing Shadow.
