I think it would be super cool if there were a way to play with your favorite cube draft decks even after the draft is over. Here are my 3 ideas, but anything would be cool.

With Friends: Just have a place in the decks builder where you can save cube draft decks, and then you can challenge a friend with the deck. You can still have it count towards your 100, and people still have to pay to do the draft to have a deck to play with.

Very Generous Idea: Just have a room where people can queue and replay old draft decks. A version of this could be something that rotates into midweek magic, where you have a curated set of draft decks people who have never cubed can pick from (to entice them into cube:)) But there's also an option that you can see all your draft decks from the past month and choose one of them.

Monitized idea: Have a big event each quarter where you can look at all your powered cube drafts over since the last event, pick one, enter the event with it, and then play for some big prize (like the arena directs). I personally probably couldn't afford to play this one, but it would make for super cool content as all the arena cube drafters battle it out, and every round, each person just has super broken decks.

Just some thoughts. I had a cool draft deck, and it would just be fun to be able to keep playing with it again, even now that the draft is done.
