@smmenen Good read! Very cool with a tool that can measure diversity. Seeing is believing.
My only critique of your article would be that it wasn't immediately obvious that you flipped the index. You wrote
Recall that a higher value indicates a more balanced and more diverse metagame, and a lower number indicates a less balanced and less diverse metagame, with .99 being a nearly perfectly balanced and diverse metagame with a plethora of viable decks, and a value closer to 0 being a metagame dominated basically by a single deck.
But for that sentence to make sense, you would have to have read the endnote as you make no mention above of why this changed.
You're not cutting a creature in the matchups you bring in Gisela or the dragon. That feels incorrect. I think Muldrotha's out vs. shops and Xerox.
I would probably cut an Island vs. at least dredge.
Maybe @brianpk80 can answer this better, but I think you can cut a number of oaths in the PO matchup.
Depending on the flavour of dredge, I think you can cut 0-2 FoW.
@forceofnature I saw this and decided to dust of my math skills.
F(n): Number of copy effects after nth Bonus Round.
- F(0) = 0
- F(1) = 1
- F(2) = 1 + 1 + 1 = 3
- F(n) = 1 + F(n-1) + F(n-1) = 1 + 2*F(n-1)
Everytime you play BR you get
- one extra copy effect for the spell: 1
- one extra copy effect for every previous one: F(n-1)
- all the previous ones: F(n-1)
Which is a really complicated way of saying playing an instant or sorcery after the nth Bonus Round will put it's effect on the stack 2^n times.
