Diagnosis - June 28, 2026

Yawgmoth is still viable but not a major share deck. MTGDecks’ last-two-weeks Modern page has Golgari Yawgmoth at 1.44% of the field, 28 decklists, and 48% win rate. The top of the format is currently Izzet Affinity, Boros Energy, Izzet Prowess, Eldrazi Tron, Esper Reanimator, Eldrazi Broodscale Combo, Boros Wildfire, and Grixis Reanimator.

The successful Yawgmoth lists this week mostly confirm the existing split: classic Golgari Cauldron/GSZ remains the default, while Chord/Birthing Ritual is still a real branch but looks more like a separate adjacent shell. The most relevant recent finishes are Xerk, 16th in the June 27 Modern Challenge 64, ShikiXYZ, 8th in the June 24 Modern Challenge 96 and 5th on June 23, plus several June 26 League 5–0s by Downfall89, Jrcitizen, and NickBolas90.

Notes on the lists

#

Xerk’s June 27 Challenge list is the most relevant current benchmark: 4 [[Yawgmoth, Thran Physician]], 3 [[Walking Ballista]], 4 [[Agatha’s Soul Cauldron]], 3 [[Green Sun’s Zenith]], 4 [[Malevolent Rumble]], 1 [[Dredger’s Insight]], 1 [[Chord of Calling]], 1 [[Haywire Mite]], 2 [[Grist, the Hunger Tide]], with sideboard [[Ashiok, Dream Render]], [[Culling Ritual]], [[Endurance]], [[Fatal Push]], [[Force of Vigor]], [[Fulminator Mage]], [[Soulless Jailer]], [[Thoughtseize]], [[Vexing Bauble]], and [[Witherbloom Charm]].

ShikiXYZ is still on the other major classic branch: 3 Yawgmoth, 3 Ballista, 4 Cauldron, 3 Green Sun’s Zenith, 3 Malevolent Rumble, 1 Dredger’s Insight, 2 Chord of Calling, plus [[Virulent Emissary]], [[Orcish Bowmasters]], [[Ouroboroid]], [[Sephiroth, fabled SOLDIER]], [[Formidable Speaker]], and a very stock interactive sideboard.

NickBolas90’s June 26 League 5–0 is the new-card watchlist list: it includes 1 [[Mole Man, Moloid Master]], 1 [[Virulent Emissary]], 2 [[Chord of Calling]], and the usual Cauldron/GSZ package. MTGGoldfish also flags Mole Man, Moloid Master as a “New Card Seeing Play” in that June 26 League, specifically in a Yawgmoth 5–0.

How Yawgmoth adapted this week

#

The main adaptation is that Chord of Calling is back as a small package, not a full return to old Chord Yawgmoth. Xerk used 1 Chord, while ShikiXYZ and NickBolas90 used 2. The clean stock lists still exist, but the better-performing Challenge lists are hedging with instant-speed access to Yawgmoth, Endurance, Haywire Mite, and singleton creatures.

The second adaptation is that Dredger’s Insight is being trimmed in Chord builds. Downfall89 stayed on 3 copies in a stock League list, but Xerk, ShikiXYZ, and NickBolas90 each used only 1. That suggests the current tension is “more engine density” versus “more tutor flexibility,” and the Chord branch is choosing the latter.

The third adaptation is that Haywire Mite is now normal, not experimental. It appears maindeck in Xerk’s Challenge list and in ShikiXYZ’s sideboard. Its appearance is a deckbuilding signal that the artifact/enchantment pressure is high enough to justify a tutorable answer.

Decks pressuring Yawgmoth

#

Izzet Affinity remains the biggest problem. It is currently the top MTGDecks last-two-weeks archetype at 9.48%, and it keeps showing up in high finishes: 2nd in the June 24 Modern Challenge 96, Top 16 in the larger June 27 Challenge, and multiple Top 8 slots in the smaller June 27 Challenge.

Boros Energy and Boros Wildfire are still the main fair-deck cluster. Boros Energy is the second-largest last-two-weeks archetype on MTGDecks, while Boros Wildfire won the June 27 Modern Challenge 32 at 10–0 and also placed another copy in the Top 16.

Grixis / Esper Reanimator is the graveyard pressure point. Grixis Reanimator was 2nd and Top 8 in the larger June 27 Challenge and also a major share of that Top 32; Esper Reanimator is a tier-one metagame deck by current MTGDecks share.

Ruby Storm, Belcher, Simic Ritual, and 4 Color Ritual are the “do not stumble” matchups. Ruby Storm won the smaller June 27 Challenge, and the larger June 27 Challenge included Ruby Storm, Simic Ritual, Red Belcher, and 4 Color Ritual in the Top 32 spread.

Jeskai/Azorius Control and Blink are the anti-creature-control pressure. Jeskai Control won the June 24 Challenge 96 and finished 2nd in the smaller June 27 Challenge; these decks are also the reason opposing Wrath of the Skies, High Noon, and countermagic-heavy sideboards matter.

Sideboard cards overperforming

#

[[Vexing Bauble]] is still the most important noncreature sideboard card. It was the No. 1 most-played card in the larger June 27 Challenge and No. 2 in the smaller June 27 Challenge and June 24 Challenge 96.

[[Surgical Extraction]] is rising because of Reanimator, Living End, and graveyard-adjacent combo. It was No. 2 in the larger June 27 Challenge and No. 9 in the smaller June 27 Challenge. Yawgmoth does not always want it over [[Endurance]]/[[Soulless Jailer]], but it is a real metagame card.

[[Consign to Memory]] remains one of the defining sideboard cards of the format, but it is not a Golgari pickup. Its continued high ranking mostly tells you that the field is geared toward Eldrazi, artifacts, Amulet, and big colorless threats.

[[Wrath of the Skies]] and [[High Noon]] are the opposing cards to respect most out of white decks. Wrath was a top-ten card in the June 24 and June 27 Challenge data, while High Noon was also top-ten in the June 24 and smaller June 27 Challenge.

For Yawgmoth specifically, the sideboard spine remains: [[Fatal Push]], [[Thoughtseize]], [[Force of Vigor]], [[Vexing Bauble]], [[Endurance]], [[Soulless Jailer]], [[Fulminator Mage]], [[Culling Ritual]], [[Haywire Mite]]/[[Outland Liberator]]. That exact package is repeated across Xerk, ShikiXYZ, Downfall89, Jrcitizen, and NickBolas90-style lists.
