Good — "nature's rhythm" wasn't found directly. Given the cards described (Ouroboroid, Badgermole Cub, Quantum Riddler, Spider Manifestation, Craterhoof Behemoth, Brightglass Gearhulk), this sounds like it maps to Simic Cub or Bant variant. Let me check Simic Cub overview, and also search for the mono-white archetype and the other cards to confirm identity. I'll also get card IDs for the filtering.
The deck is Simic Cub (Nature's Rhythm is a key card in that archetype). Now I need to:
Interesting — 0 entries with both Brightglass Gearhulk AND Seam Rip in main. Let me broaden - maybe the constraint should be either card, or check a wider date range, or check what Simic Cub entries have white cards in main at all.
Neither card appears in any Simic Cub mainboard in the date range. Let me check if they appear in the broader standard dataset at all, and also check if any Simic Cub entries have any white cards mainboarded.
Good — both cards appear in 968 entries across standard mainboards, but not classified under Simic Cub. Let me check which archetypes those entries belong to, and also check white-splash Simic Cub more broadly.
I'm hitting query issues — let me fix the SQL syntax and try simpler queries:
The archetype is classified as Bant Cub — it has both Brightglass Gearhulk (49 entries) and Seam Rip (48 entries) in main. Let me now get that archetype's overview and run the matchup analysis.
Bant Cub confirmed — it has all the key cards (Badgermole Cub, Ouroboroid, Nature's Rhythm, Craterhoof Behemoth, Spider Manifestation). Now I need to specifically filter to entries with BOTH Brightglass Gearhulk AND Seam Rip in main, then get matchups vs all top 20 archetypes. Let me also check mono-white with Momo — from the earlier data, "mono white aggro" had 4x Momo and is NOT Boros Dragons.
48 qualifying Bant Cub entries with both Brightglass Gearhulk and Seam Rip in main. From earlier, "mono white aggro" has 4x Momo. Now let me check which mono-white archetypes feature 4x Momo to make sure I pick the right one, and then run the matchups for the white-splash Bant Cub entries vs all top 20 archetypes.
The matchup data is showing all zeros for wins/losses/draws — the result field values might be different. Let me check the actual result values in the matches table:
Results are WIN/LOSS/DRAW. Let me re-run the matchup query with correct values:
Excellent! Now I have all the data I need. Let me also get sources and confirm the mono-white aggro archetype overview.
Now I also need to confirm which Izzet Midrange archetype is in Standard (the one with prowess/midrange pattern). Let me check the standard one specifically and also add the alias for Bant Cub being the "Bant/Nature's Rhythm" deck.
The Izzet Midrange in the matchup query correctly shows 18 matches, 7 wins, 10 losses, 1 draw for the white-splash Bant Cub. Now I have everything. Let me also add the alias for "nature's rhythm" → Bant Cub (since that's the engine card), and compile the full response. The mono-white archetype is confirmed as Mono White Aggro (id: 05e97791) with 4x Momo, Friendly Flier.
Alias creation is restricted — no worries, I have everything needed to compile the answer.
The deck you're describing is classified as Bant Cub — a white-splash variant of Simic Cub built around Nature's Rhythm, Badgermole Cub, Ouroboroid, and Craterhoof Behemoth, with the white addition of Brightglass Gearhulk and Seam Rip. There are 48 qualifying entries in the last 30 days with both of those white cards in the mainboard.
Restricted to entries with Brightglass Gearhulk + Seam Rip both in maindeck. Win% excludes draws.

vs Izzet Midrange (Prowess): 7-10-1 → 41.2% win rate — a losing matchup for the white splash build. The speed and interaction density of Izzet Midrange appears to be a real problem.
vs Mono White Aggro (4x Momo, Friendly Flier — NOT Boros Dragons): The "Mono White Aggro" archetype with 4x Momo confirmed — no recorded matches in this filtered sample (too small a presence to generate games against this specific Bant Cub variant). Insufficient data to report a win rate here.
