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
Another striking case was the special art rare Trainer card Iono from Clay Burst (Japanese set) versus Paldea Evolved (English)
it cant quite snowball a game the way Ocelot Pride or Ragavan, Nimble Pilferer do, but the steady stream of card advantage via Clue tokens that pivots into a planeswalker gives slower decks a powerful threat
This trick can also be notably done with Valki, God of Lies, who has three appearances in this deck
This means you can exile a bunch of your opponent's tokens with no drawback
Though completely useless in an actual deck for the trading card game, The One Ring is worth a significant amount to Magic: The Gathering collectors considering that Wizards of the Coast the studio responsible for releasing the card game printed a single copy to thematically reflect the significance of The One Ring within JRR Tolkiens trilogy of books
