Would be most excellent to make a dynamic matchmaker. If a player has found secret sauce and actually stands a chance, let them pair up.

However opponent here has 5 colours. What am I supposed to do with 1 colour. Green. The fairest of them all. I’m not talking about the odd game I can win against a slow Golos player. Wishing on my opponent to be bad or to give me a handicap isn’t playing Magic.

Monocounter spells happens to be ok against Golos but opponent can figure out other ways to play the game.

I've noticed Bill and Marwyn have a similar treatment to 5 mana Vorinclex. These three can get 4 and 5 colour matchups.

Whereas when you are running Tyvar Kell as commander, that deck can be quite hasty and win from 1 life and a dream (involving hasted mana and playing your entire deck out to get to Hoof or Shaman of the Pack). (Which is to say Tyvar Kell, when built to have hasty mana, this deck has a decent win ratio, ~55% to 45% matchmaking. Though recently, Tyvar Kell is matching into harder decks.) (Bill and Marwyn have atrocious matchups. Vorinclex feels a bit more fair until you get to the 4 and 5 colours.)

If Brawl and EDH is so important to WotC, maybe make sure the experience feels good for players. Currently MTGA’s Brawl is missing some key aspects (social aspects).
