@stormanimagus you can try reporting a bug as explained here. I don't think there are actually any plans to fix it as it hasn't technically been released online, it was just available during all access.
I might consider just going with cards that either have massive (affects everyone) effects, or go with targeted removal or interesting creatures.
(Given my experience may not equate to yours.) This is the most dangerous part. The players shouldn't be able to rely on the pile for things like wraths and removal because then you can build a deck with none of them and just lean on the pile. Making the pile consistent in any way is the single thing I found most enabling of the troubles.
Not necessarily they may just get lightly worse bragging rights, still winning an immense tournament just not THE immense tournament. Also I don't agree with arbitrarily deciding the NA one is the real one but it is less dismissive than you make it sound.
