Priest of Yawgmoth

The upcoming release of Phyrexia: All Will Be One promises to thrust the Phyrexians back into the spotlight. Let’s go back through the history of these long standing villains from Yawgmoth to the present day and analyse what makes them so formidable.
Yawgmoth and “Old Phyrexia”

The story of Phyrexia begins with the story of Yawgmoth. Yawgmoth was a doctor native to the Thran Empire, an ancient but technologically advanced civilization which thrived during Dominaria’s early history. Yawgmoth was called to the Thran capital of Halcyon in order to treat a disease known as
Phthisis

Suspend 5—{1}{B} (Rather than cast this card from your hand, you may pay {1}{B} and exile it with five time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.)
. Yawgmoth’s cure for Phthisis involved replacing diseased organic limbs with artificial ones, a process he named
Phyresis

Enchanted creature has infect. (It deals damage to creatures in the form of -1/-1 counters and to players in the form of poison counters.)
. Yawgmoth was able to deceive a Planeswalker named Dyfed into opening a portal to a new world, which he claimed he would transform into a paradise where he would care for the ill. Yawgmoth instead corrupted this world into the nightmarish hellscape of Phyrexia. He transformed his patients into an army of grotesque partially synthetic, partially organic monstrosities.
Yawgmoth’s horrific experiments were uncovered and the Thran Empire fell into civil war. At the end of this war, the Thran capital of Halcyon was destroyed in a cloud of deadly gas, ultimately leading to the fall of their civilization. Though the Thran Empire fell, Yawgmoth and the Phyrexians were sealed away and the portal to their realm was closed off.
Many thousands of years later, the brothers Urza and Mishra unintentionally reactivate this portal to Phyrexia during a search for Thran relics. The Phyrexians gradually corrupted Mishra, leading to the Brothers’ War. Urza prevailed over his brother, but at a steep price. The war ended with Urza detonating a superweapon known as the
Golgothian Sylex


Exile all nonland permanents that aren't legendary.
. The blast also awakend Urza’s spark, transforming him into a planeswalker.
Having won the war, Urza realised that the Phyrexians were the greatest threat to his world. He spent generations devising a plan to stop them. Urza resorted to some less than moral means, such as instituting “the bloodlines project” a program designed to breed the perfect hero over hundreds of years. The project resulted in the birth of
Gerrard Capashen

{3}{W}: Tap target creature. Activate only if Gerrard Capashen is attacking.
Urza’s most powerful pawn in his mission to destroy the Phyrexians. When the Phyrexians eventually did invade Dominaria again, Urza was ready for them. Using a series of powerful artifacts known as “the Legacy”, alongside sacrificing his and Gerrard’s life, Urza was able to kill Yawgmoth and destroy the Phyrexians for good. Or so it seemed…
Mirrodin and New Phyrexia

One of the powerful “legacy” artifacts used to destroy Yawgmoth was the silver golem, Karn. The strike that killed Yawgmoth caused Karn’s spark to awaken, enabling him to planeswalk. Karn constructed his own plane, a mechanical world that became known as Mirrodin. Unfortunately, Karn unknowingly tainted his new world with Phyrexian oil. This

, a golem Karn appointed as the guardian of Mirrodin. Although Memnarch was defeated, in 2003-20004s Mirrodin block, the corruption did not stop with him. The storyline of 2010-2011s Scars of Mirrodin block depicted how the plane was gradually overwhelmed by Phyrexian influence, as the glistening oil spread. The plane’s greatest champions were corrupted, in a process known as “compleation“, turning them against their home.

.
In a unique marketing strategy, Wizards of the Coast refused to provide the name of the final set of Scars of Mirrodin block. They marketed it both as Mirrodin Pure and New Phyrexia. Ultimately, however, the Mirrans lost their war and the plane of Mirrodin was warped and twisted into New Phyrexia.
Whilst the original generation of Phyrexians were associated with Black mana, the new generation created on New Phyrexia were different. The plane has five suns, one for each color of mana. These suns influenced the development of five seperate Phyrexian factions, each led by a Praetor.

The Phyrexian Arc

For a long time after the conclusion of Scars of Mirrodin block, the Phyrexians were content to lurk in the shadows biding their time. We spent nine years getting only fragmentary snapshots of what was happening on New Phyrexia. The printing of

Then the Phyrexians came roaring back into the foreground, with the release of Kaldheim in 2020. The card

No longer content to wait on the sidelines, the Phyrexians appeared again in Magic’s very next set: Streets of New Capenna.

Fortunately, the artificer Saheeli Rai was able to create a perfect replica of the Sylex. The time manipulating magician Teferi traveled back in time to the Brothers’ War in order to find out how to operate it. He succeeded and passed this knowledge along to characters in the present, but ended up getting Desynchronized from time.
