I had considered doing a full article and analysis about this but life happens on occasion. Major props to Ryan Eberhart (Diophan) for his help in collecting the data.
TLDR: Many viable archetypes with significant diversity. Gush was statistically the best archetype with Oath and Hatebears virtually tied for the worst.
Archetype - Number (% of Metagame) - Match Win %
Shops - 21 (20.4%) - 49.6%
Ritual Storm - 16 (15.5%) - 51.1%
Dredge - 16 (15.5%) - 50.5%
Gush - 15 (14.6%) - 58.2%
Oath - 10 (9.7%) - 43.4%
Big Blue* - 8 (7.8%) - 52.0%
Hatebears - 5 (4.9%) - 43.8%
Other** - 12 (11.7%) - N/A
*Loose category of TfK + Tinker/Robot + Yawgmoth's Will
**Other archetypes represented by less than 5 decks
Breaking down the major archetypes further:
Shops: Ravager 8-50.5% MWP, Aggro (Montolio's list) 5-48.3%, Tiny Robots 4-45.8%, Other 4-50.0%
Dredge: Traditional Antihate 9-51.9%, Pitch 5-50.0%, Other 2-45.5%
Ritual Storm: All of these were Dark Petition variants and very similar
Gush: Mentor 11-57.7%, Delver 3 - 61.9%, Gush Tendrils 1-50.0%
Oath: Odd Oath 5-51.6%, Other 5-31.8%

Shameless Plug: Mentor CounterTop was 2/2 on making the top 16.
Unfortunately, Vasu and I were 0/2 in our win-and-ins.
