There's almost no downside, and putting a card like Ulamog, the Ceaseless Hunger or Karn Liberated underneath Ugin's Labyrinth via imprint only to pick it back up when casting it is easier adds a layer of versatility to the Tron strategy that will make it even more of a threat than it has been previously

They adore mana acceleration, Elves, and early dorks that can become later threats
