@JonTheMon I haven't been keeping up with standard a lot recently, but from what I've seen the Uro banning will be a big nerf to landfall (take this with a grain of salt, I'm not the most informed on the format). However, it doesn't completely invalidate landfall, and it was also a key piece in other decks that may have fought landfall, so it remains to be seen whether it'll affect the metagame as heavily as I think it will
