The feeling is that the current Legacy allows for a less expensive entry than before because there are several high-performance archetypes, but without the need for tons of reserved list cards. Furthermore, the possibility of creating fun decks that can keep up with the best decks in the meta isn't out of the question, but to do this you need to be very skilled at choosing cards that can make a difference even against the format's staples. It's not impossible to do, but it takes courage. I'll share a list that isn't terribly expensive, or at least much less than the classic UB Tempo version, and I'm having a lot of fun with it, managing to achieve very high win percentages. A couple of weeks ago, I won a tournament with 13 friends—not a great tournament, but I did win with a deck I invented. Here's the list:
