Karn is love, Karn is life.
It's not about making more deck types in the format.
I think there is room in Vintage for many more decks in the meta-game and I think the cost is preventing new players from getting into paper.
Ok, buddy. I'll answer the OP's question while you answer the ghosts in your head.
According to Betteridge's Law of Headlines, the answer is no.
In my opinion, the answer is no because it assumes that the price of the format is the absolute deterrent to players as well as innovation. My recommendation, at least for the innovation department, is to dig up the data from North America Eternal Weekend 2018 (it contained every decklist, lucky us) and Magic Online around the same time. Since Eternal Weekend is a significantly larger player pool, and your hypothesis is that a larger player pool leads to many more decks, you'll probably find your answer there.
The rest of your post is personal bias towards Magic Online.
You haven't substantiated any of your positions. You haven't provided tournament results. You haven't mentioned any records. You've cited "testing" but what does that consist of? Who are you playing against? Are you competing in large scale events against competent opponents who have posted consistent finishes with their lists? Tell me why I should consider what you are saying over literally everything else I have seen about the format.
Your newest post doesn't do this either.
There's a contingent of Vintage players that don't understand how to create, interpret, or in any way use data in a positive way. They tend to be more enfranchised players that did well long before Black Lotus was on MODO and the online data was an option for them to improve their game. They become bitter when they see people use the new ways to become better than the members of the old guard. They think they're just as knowledgeable but simply don't have the time to prove it due to adult duties such as children, aging parents, or any other aspects of reality. They use the term "noob" as a negative epithet because it's how you insulted your fellow gamers twenty years ago.
Please don't stoop to their level. Your streaming content and intelligent posts are far more important than shit-slinging with the bitter has-beens. Please be better.
@moorebrother1 Thankfully a Karn, the Great Creator thread already exists with many of the talking points you've highlighted:
Additionally, @Stuart made a fresh thread now that Karn has successfully pivoted from spoiler season speculation to Vintage all-star. It looks more to garner discussion amongst Karn pilots, whereas your thread gives off much more of a self-serving vibe:
The latter thread is still fresh, but I'm sure it'll pick up as people come and go.
I will be there as well, hosting the Old School event on Thursday, and playing Vintage on Friday. Looking forward to playing in a 20 person Vintage tournament for Power.
Nothing spells out doom and gloom quite like the owner of a Vintage website saying a large Vintage event is going to fail. There's quite a bit of truth in that considering it's a lame duck format that's a week away from getting new printings.
