This is really rough
Even if you arent casting your opponents cards, youre still denying them access to whatever card you exile, which can sometimes have a huge impact
Even today, seven itchy years distant, pundits, commentators, and ex-PTQ players will not agree who had the matchup (personally, I was 14-0 against Donate with The Rock in 2001, never losing a game and winning both a GPT and PTQ)
While there are solid cards like Cut Your Losses for Bruvac mill or Hypnotic Grifter as a mana outlet in a self-mill deck, theyre a little niche and otherwise not going to add too much to your collection
And instead of going with a reprint, they make us all go out and find four new copies of the same card weve already been playing with for the past year and strictly downgrade its flavor
For instance: A deck with a commander that costs two mana may avoid 2mv ramp because it anticipates playing its commander on turn two instead of ramping
