Decks like these have been popping up in Daily Events for a while now, but I really like this one.
For starters, there's the maindeck Carpet of Flowers, which, as we've seen previously, is very powerful in the right metagame. Treasure Cruise might not be around anymore, but the average metagame is still 60% blue decks, so Carpet of Flowers will be on more often than not.
In case you haven't seen a deck like this before, Thespian's Stage or Vampire Hexmage combo with Dark Depths to make a Marit Lage token. Crop Rotation, Expedition Map, and Sylvan Library help you find your combo pieces, while Pithing Needle shuts down opposing Wastelands. Swords to Plowshares is kind of an issue, but discard or Crop Rotation for Sejiri Steppe can solve it.
