I think your "schools" approach feels a bit... shoehorn-y at times (in that Rob Hahn might not translate that well to
Having said that, as a combo player combo decks by their very nature are very disparate in a way control and aggro really aren't. Decks like ProsBloom, Metalworker, Doomsday, Dredge, etc. function so differently it's hard to categorize them together. Speaking of which, was there a Type I combo deck before Type II ProsBloom hit the scene? If not, maybe that's a good place to start.
To be clear: that's not how I classify decks within the "Combo School." The combo decks that are included in the "Restricted List Combo School" follow a very specific play pattern that includes: lots of mana acceleration, a high density of restricted cards, and a number of tutors (often unrestricted), and either a big mana or storm finisher (e.g. Fireball, Kaeverk's Torch, Tendrils of Agony), or recursive elements (like Twister loops or a bigYawg Will). Thus, decks in this school include: Pre-DCI Lotus/Twister decks, 1997 Prosperity Vice, 1997/8 Doomsday (recursion deck with Timetwister), 1998-2002 Academy, 2002 Burning Long, 2003-2008 TPS, 2005-6 Grim Long, Burning Oath, Dark Petition Storm, etc.
These are decks that follow the basic play pattern of: 1) generate lots of mana -> 2) draw or otherwise see lots of cards -> 3) play a critical mass finisher. They feature as high density of mana, and very few finishers (a single Fireball or Tendrils often). And they very often use disruption to protect this plan, like Duress, Defense Grid, Abeyance, City of Solitude, Xantid Swarm, Force of Will, etc. But if you map 2002 Burning Long and 2015 DPS, it's basically the same scaffolding, just different cards in that slot. No different with other Schools, like comparing 1994 The Deck with 2002 Keeper, except that the win conditions change (i.e. Morphling over Serra Angel, etc.)
Combo decks that are focused on assembling two random cards don't fall into this school.
ProsBloom was never a tournament level Type I deck because you didn't need Cadaverous Bloom.
That being said- in your position, I'd focus on the decks. Tell us when new, interesting things happened that changed the way we think about and play Vintage (or even Magic as a whole). Tell us those stories. Weave together the fabric of the format by showing us the world as it was when it changed greatly. What was it like when Comer figured out how to Xerox? How did it change the landscape? Which darlings did it kill? Which did it foster? How does it influence what we're doing today? The same for Shops (the more control variants, the ones today are really just Zoo decks imo) and Dredge and Oath and Control (the Deck, of course, comes to mind!). The schools can be your invisible scaffolding, that which guides you in delivering the stories, but they need not be the exoskeleton that binds the body from the outside and is all that's visible to the onlooker.
In any case, I do all of these things, but the Aggro Shops decks are still very obviously Aggro O'Brien School decks, which played with 4 Juggernaut and 4 Juzam in some cases.
Thanks to everyone who replied: it affirmed my inclination, which is to take a hybrid approach rather than trying to insist upon a player name for each school.
Has anyone considered looking outside Mentor and Workshops for solutions?
The short answer is yes.
Gunmaster7 who won the last MTGO Challenge with Dredge did
The winner of the 50 person GP Kyto side event with BUG Fish did
Kurato Yoshihiko who just won the 72 person Vintage God Challenger LCQ with Outcome did
Eduardo Medrano who just won LCV in Barcelona with Bant Fish did
Tim Everett who just won the Ruyard's Pub event in Texas with Merfolk did
James Vogul who just won the Knight Ware EW Trial with Outcome did
Mike rogers who just won the RIW Hobbies in Michigan with 2 Card Monte did (sort of, 2CM has Workshops but I think it's very fair to call it a different archetype)
That all happened in July alone. I was only able to find 4 paper events in July that Mentor or Shops won (and one of them is a 2 Mentor Outcome deck which I think barely count) - Firenze, TopDeck Games, Vintage At Escape, and MKM Series.
That's just looking at tournament wins. An Omni-Tell deck, a BUG Fish deck, 2 Punishing Oath decks, and a Hatebears deck running Rhonas the Indomitable just top 8'd a 72 person event in Japan. Rector Omniscience and Grixis Painter just top 8'd a 30 person tournament in Prague. U/B Outcome, Spell-Queller/Stoneblade, Dark Petition Storm, Magus of the Future Outcome, Emrakul/Remora/Stoneforge Control, and Baral+Gifts Ungiven Combo/Control have all top 8'd Vintage Challenges this month. That last Gifts deck may actually be the deck on MTGO with the highest match-win-% right now, but it has a much lower total set of wins because very few people are playing it. (The math is pretty tricky to figure out on that one). Again, this all happened in July alone.
Yes, Workshops is the best performing deck in most metagames overall, and yes Mentor is likely second.
Despite that, lots of players are choosing to play other decks and being rewarded for it. The kind of conversations that lead to those choices just don't seem to be happening on TMD.
Fortunate enough to have started MTG during Beta, but then unfortunate in terms of having my ridiculously valuable collection stolen a few years later. It was definitely a different game back then. I remember everyone's excitement when Colossus of Sardia came out because 9/9 was suddenly the new 8/8. I also remember the release of Antiquities especially because I traded for all my friends' Moxen and Lotuses to create an Atog deck with all artifact mana. I think at one point I had 30 Moxes and 5 Lotuses. Again, quite a ridiculous collection. Of course, most of us were also playing "house rules" back then, and commonly this included drawing two cards per turn and playing as many lands as you like per turn. This obviously devalued things like Moxen, Lotus, Ancestral, and Library in our circle, so I'd pick up a couple Moxen on trades for something silly like a Lord of the Pit. Ah, the good old days.
