Mono-Green Devotion Returns With Three Pioneer Challenge Top Eights

Mono-Green Devotion took three top-eight places in the November 7 Pioneer Challenge 16, led by HouseOfManaMTG’s third-place finish at 5–2. MTGO’s published results put Nougatygoodness seventh at 4–2 and wolf2222 eighth at 2–3 in the 31-player event.

That result follows a sharp October return rather than an uninterrupted climb. We consider Mono-Green Devotion a credible tournament choice again, but its recent results put it below the pace of its mid-October peak: the six-week run produced 48 published lists, 12 top eights and 1 win.

The October Peak Has Settled Near 6%

Mono-Green Devotion went from 0 of 57 published MTGO lists in the week of September 28 to 6 of 115, or 5.2%, in the week of October 5. It slipped to 3 of 122, or 2.5%, on October 12, then jumped to 20 of 121 lists, or 16.5%, in the week of October 19. That peak week supplied 5 top eights and the archetype’s only win in the six-week period.

The following completed weeks were lower: 9 of 153 lists, or 5.9%, on October 26, then 8 of 127, or 6.3%, on November 2. The partial week of November 9 also sits at 6.3%, but that is only 2 of 32 lists.

The rolling seven-day window through November 12 gives a different cut: 7.1% of 127 lists, up from 3.9% of 153 in the preceding window, with 3 top eights and no wins. The circulated 8.4% figure belongs to the week of August 10 on MyMTGO’s weekly page, not November.

Badgermole Cub Replaces Leyline of the Guildpact

All three November 7 top-eight lists played the same 60-card main deck, including 4 Badgermole Cub and no Leyline of the Guildpact. HouseOfManaMTG’s October 29 list, which finished seventh at 4–3, instead had 4 Leyline of the Guildpact and no Badgermole Cub. This is adoption across three pilots, not a single unusual finish.

Badgermole Cub costs , earthbends 1 when it enters and adds an additional whenever you tap a creature for mana. It amplifies Llanowar Elves and Elvish Mystic rather than replacing their turn-one job. Compared with Leyline of the Guildpact, it moves the acceleration into a creature that also turns a land into another creature-based mana source.

The plan still starts with a turn-one mana creature, then builds toward Nykthos, Shrine to Nyx and Storm the Festival. HouseOfManaMTG played 21 lands and 8 one-mana accelerators, with Old-Growth Troll bridging into Cavalier of Thorns. Kiora, Behemoth Beckoner helps convert those large creatures into more cards and another use of Nykthos, Shrine to Nyx.

Izzet Cauldron and Golgari Midrange Have Beaten It

The six-week top-eight playoff record is 2–0 against Izzet Spellementals but 0–2 against Izzet Cauldron. Mono-Green Devotion also lost its single observed playoff match against each of Jund Sacrifice, Mono-Black Midrange and Golgari Midrange. These are small samples, but Izzet Cauldron stopped the best November 7 run: Capriccioso beat HouseOfManaMTG 2–1 in the semifinal before winning the event.

Fast aggro attacks the deck’s vulnerable opening. TCG Playbook’s October 27 guide calls that pairing unfavorable because removal can kill the mana creatures while early attackers pressure life totals before the expensive threats arrive. Its plan is to stabilize with blockers, trim slow top-end and bring in cards such as Setessan Petitioner and Arasta of the Endless Web. HouseOfManaMTG’s current sideboard has 2 of each, plus 3 Tail Swipe.

Against control, the same guide recommends Arasta of the Endless Web and Emrakul, the Promised End; against combo and graveyard strategies, it recommends The Stone Brain. HouseOfManaMTG has 2 The Stone Brain and 2 Unlicensed Hearse, while the other two November 7 pilots chose 3 Unlicensed Hearse and no The Stone Brain. Their main decks agree; their allocation of narrow answers does not.

The Next Challenge Results Matter

MandrillMan’s October 19 victory, a 7–2 finish in a 46-player Challenge, remains the strongest result of this return. Mono-Green Devotion then missed the published top eights of both the November 8 Challenge and the November 10 Challenge. The next useful step is another deep finish from the Badgermole Cub build, particularly through Izzet Cauldron or Golgari Midrange rather than a mirror match.
