In the event of such an overhaul, please keep in mind that many of us like to use multiple different printings of the same card with different art in a single deck, such that selecting which printing to use on a per-deck basis would be a feature downgrade for us.
(Ideally, i would prefer it if styles were per-card rather than per-deck as well)
Definitely! This is more about streamlining deck building for those who want it than removing features that people enjoy. If you want to manually make every land a different printing, you will still be able to do that in the designs we have been looking at.
