Good ā "Bant Nature's Rhythm" wasn't found directly. The card list (Ouroboroid, Brightglass Gearhulk, Badgermole Cub, Spider Manifestation) strongly points to Simic Cub (with a splash of White for Brightglass Gearhulk making it Bant). Let me check that archetype and the mono-white flier deck, and get all the matchup data simultaneously.
Good ā Simic Cub is confirmed (Badgermole Cub, Ouroboroid, Nature's Rhythm, Craterhoof are all key cards). The Bant version splashes White for Brightglass Gearhulk. Now let me search for the mono-white deck and get the correct Izzet Midrange for Standard, plus kick off all the matchup winrates.
Now let me check which mono-white archetype features 4x Momo, and then fire off all matchup winrates at once.
Interesting ā Boros Dragons is the top archetype running 4x Momo by a wide margin (348 entries). Let me get the Simic Cub matchups vs all top 15 + Izzet Midrange + Boros Dragons now.
Here's the full breakdown!
Your "Bant Nature's Rhythm" deck is classified as Simic Cub ā the key identifiers are Badgermole Cub, Ouroboroid, Nature's Rhythm, and Craterhoof Behemoth. The White splash (Brightglass Gearhulk) and Spider Manifestation/Quantum Riddler are in-archetype variants; the core is firmly Simic.
The archetype running 4x Momo, Friendly Flier at scale is Boros Dragons (348 entries, avg 4.0 copies) ā not a mono-white deck. "Mono White Aggro" exists in the DB but had only 4 recent entries with Momo. I've included Boros Dragons as your requested matchup.
