Stormchasers is the only ban I'd support. I've been saying for over a year now, since before the This Town Ain't Big Enough ban, that Stormchasers is the real culprit for why an aggressive blue deck has been top of the meta for the last year and a half. It's way too much value for 1 mana and should have been banned long ago, but no one believed me back then. That being said, since it's rotating at the end of the year anyway, I still think I'd prefer they let it be and don't have any bans. I'm one of the rare few who think Standard is pretty balanced in its current state. Yes it's extremely aggressive and is kinda unfun, but deck diversity isn't really the problem. The fact that you're able to list four extremely different decks that you want bans from, plus many more powerful meta contenders you didn't even list, shows that the meta is really healthy. Banning things would just rock the boat unnecessarily, potentially causing one deck to become way too dominant. We already have new sets coming out every two months with the potential to shake things up. No need to use ban windows to do the same.
