During this week's tournament, I had a really random idea and decided to make a monolight (unuped) hope deck. Since I earned white nymph in oracle, I thought this could actually work.
EXCEPT THAT MY WHITE NYMPH WAS ALREADY UPPED....
there should be a way, possibly requiring coins, to degrade rare cards down to their unuped state because a lot of competitions require unupgraded decks and sometimes people can't utilize cards like nymphs because they've already upgraded them.
