What do you think may or may not be getting banned?
I'm thinking Geological Appraiser definitely gets hit for Pioneer, the deck is singlehandedly warping the entire meta. Not sure about Quintorious combo. Low chance but maybe hits to Mono-G or Rakdos.
Modern could be anything. Grief, Fury, Bowmasters, Ring, Beanstalk, W&6?
Smuggler's Copter feels like it's one of those things that was banned ages ago and the format has caught up to it, as much as I'm reluctant to let anything out that could help Greasefang I think it would be fun to play with
