I upvoted this post immediately, because I'm happy to see anyone generating vintage content, but I'm just getting around to reading this now.
This was a great piece of magic writing and I sincerely hope we can get more like this in the future.
From the start, the core premise/subject matter is wonderful. There are a lot of articles and posts out there about hypothetical lists with minimal testing-sometimes no testing. These can still be great pieces, but it's rare and very valuable for someone to come into a piece with 100 documented matches under their belt. Besides the overt content of "here's the list and here are the card choices", there's this implicit message of your process. The note-taking, the discipline. Your approach and work ethic toward improving your vintage play is inspiring, and if you're not already a top vintage player, you could easily become one over time if you wanted to be. Even though it's not the focus of the piece, talking about your process (even in passing) gives it a mix of to-the-minute and timeless advice, which is exactly what players looking to improve their magic win rate should be looking for in an article.
Beyond that, the line-to-line writing is engaging. The subject matter of a pure-strategy article can be pretty dry (interesting, useful, but dry). I'm not going to say this has the raw entertainment value of a Ben Perry tournament report ... but for all the information you're packing in here, you manage to keep a conversational tone, and avoid falling into the "bad high school essay" trap. I know this is no small feat.
Thanks, again, for writing this, and I hope you decide to mix some more vintage content into your legacy work in the future.
