Guys nothings getting banned in vintages it’s restricted they go to in that
The only bans in history in vintage are the following
Ante cards (playing for keeps)
Conspiracy (has to be draft)
Throw in the air (these just cause riots from the judges)
Karn from war of the spark got restricted should be no different for Lurrus
And yes even with the companion thing and I doubt Sheldon would ban Lurrus in edh all because of vintage
Out of curiosity, what do you expect restricting Lurrus to do? That seems to be the clear front runner for "problem card" and decks currently play a grand total of 1 copy in their decks as it is now (since he already effectively restricts adding copies of himself to the deck). Restricting the card does literally nothing. Either they ban him or they simply do nothing with him. Which means Vintage remains broken (more broken than it was before).

They seemed to have gone with the simplest solution: don't use the Vintage Ban list as a base anymore.
