Galadriel enables some non-infinite combos that are surprisingly easy to assemble: with Galadriel, one of our three cards that scry when a creature enters the battlefield (Sylvan Anthem, Season of Growth, or Elrond, Lord of Rivendell), and one of our four cards that create a creature when a land enters the battlefield (Scute Swarm, Sporemound, Rampaging Baloths, and Zendikar's Roil), we can put a land into play to trigger landfall and make a green creature token, which triggers a scry, which triggers Galadriel to potentially put a land from the top of our library into play and repeat the process
