@brass-man On the contrary, I recommended a Green - Blood Moon in the hope of helping green creature style decks. This card is no better that Blood Moon except slightly cheaper and would allow green creature decks like Elves a way into the format.
I think we need to expand the format. I like your premise for card design, because what people fail to realize is there was a time before a set of cards existed and a particular deck did not exist. Like how Dredge did not become a deck in Ravnica but cards from Time Spiral made it work with Bazaar.
I am looking around at Modern and Legacy and some core decks are missing in Vintage for various reasons. Reanimator is dead, Dark Depths decks are kind of coming back. Elves is dead. Fish decks are dead. Grow decks are dead. Painter decks are dead.
We have a different format and I like it, but expanding it to include creature style combo, and some better Aggro options is good.
When we think of Aggro in this format we think of Shops for obvious reasons, let's expand that. When someone says combo most people think or Storm or Paradoxical, that is great but what about Sneak and Show or Academy or Red Storm.
Vintage like all of the other formats builds on existing efficiency, which is why it took some months before a Paradoxical deck got going and why Storm decks look very different now than they did a year ago.
How do we break efficiency norms? Usually with cards like Treasure Cruise or Dack Fayden that are too efficient, and then we complaint about the remaining very efficient cards like Mental Misstep and Workshop.
To expand the format, we need to either break efficiency of existing cards and create new efficiencies that do not exist yet.
