It looks like Standard might have an issue. And, honestly, I don't care.
Magic 2019 previews basically start next week.
Are they really as offensive as these cards?
Actually, are these cards even that bad?
I spent some time looking at how each of the banned cards would reintegrate into Standard if given one last hurrah before the Kaladesh-Amonkhet rotation and came to the following ranking, from the most broken card to the most absurd that you aren't allowed to play it.
If you ever thought unbanning Smuggler's Copter was a reasonable idea, congrats, you screwed up.
Now? The best deck in the format is an aggressive deck that already plays the best answer to Smuggler's Copter, already plays a Vehicle, and has its biggest issues with draw and curve consistency. Oh, and it has multiple graveyard and artifact synergies.
Okay, sure. Let's pretend we want to dive further into "Unbeatable R/B World." What would actually happen?
Any card that improves with controlling an artifact gets a boost. Inventor's Apprentice is notably a two-toughness one-drop that just needs a little boost compared to current artifact levels to turn the corner. Planeswalkers are a little sketchy in a metagame flooded with flying Vehicles, but Karn, Scion of Urza's -2 making a potential 3/3 or larger body is nice. Karn would also link nicely to loading up with some Heart of Kirans on top of Smuggler's Copter in a format where Chandra, Torch of Defiance is a big joke.
Great Vehicles make haste creatures worse. Just tap your new creature to crew something. Earthshaker Khenra looks like it might have nice graveyard synergy, but why would you want to keep your fifth and sixth lands to eternalize it?
Hazoret the Fervent is probably still insane. Just loot away the things that don't curve out and slam another dumb threat.
