As excited as I am for this set, I don't think Vintage will change too much. I have a hard time believing the fundamental building blocks of Vintage will disappear due to these new printings. I think it's more likely that one of 3 things will happen.
- New card slots into an existing archetype
- New card creates a new archetype that's fringe playable
- New card is messed around with for a few weeks, then fades away
I think as high as the power level of this set has been, Khans probably will have changed Vintage on a fundamental level more than the upcoming set will. As someone said, the london mulligan rule has the potential to change things more!
This spring is one of the most interesting times in Magic's long hstory.
We have War of the Spark, with so many planeswalker (including a slightly different design approach) cards that ask a lot of questions.
We have the London mulligan rule, which if adopted will alter the way the game is played and shift how we evaluate certain cards.
We have the upcoming Modern Horizons set, which has the potiential to print new cards that carry effects that will easily find a home in Vintage.
It is a fascinating time to be a magic player.
So answering the op question: there isn't such a thing as too much shake up.
Also this set does very little for Vintage IMO. Fetches, CotV, Mentor and Delve spells were way more impactful. The most important cards are Citadel, Teferi and Karn so far and none of them are format-defining-broken. Maybe Citadel if anyone figures out the right list for it. I don't think Teferi will be important like Dack Fayden.
The London Mulligan will probably shake up the format much more than this set.
@hrishi I think there are some cards that will have a longterm impact on Vintage. Paradoxical Outcome took a year to develop into a real deck. Survival took a while after Hollow One was released as well. Deck creation is a very time consuming exercise in Vintage and there are very good card to seed that creation, it just may take a year or 2.
@moorebrother1 Absolutely, and I really hope archetypes emerge which are built around these new cards. I definitely think Bolas' Citadel is one such card, and is definitely the one I want to build an archetype around when it gets released. I more just mean I don't think this set will shake up Vintage too much. We'll hopefully get a few new archetypes and a few new toys in existing ones.
