The One Ring gives slower Commander decks a growing source of cards in a colorless artifact slot. Its first activation draws one card, the next draws two, and the reward keeps increasing as burden counters accumulate. That makes it attractive to decks that can spend the extra cards while managing the life lost on later upkeeps.
Casting the Ring also provides a temporary defensive window: its entry ability gives you protection from everything until your next turn if you cast it. Simply putting it onto the battlefield without casting it does not provide that benefit. The protection applies to you, not all your permanents, and does not stop every possible way to lose resources or the game.
Voltaic Key can untap the Ring for another activation, while Unwinding Clock lets an artifact-heavy deck untap it during other players’ untap steps. Each additional activation adds another burden counter before drawing, so these partners accelerate both card flow and the life loss at your next upkeep. Plan how you will use the cards before repeatedly untapping it.
Plan around your life total and how quickly you can use the cards. Leaving the Ring tapped does not remove its counters or prevent its upkeep trigger. Indestructible helps against destruction effects, but exile and bounce still answer the artifact. It is most useful when your deck needs sustained draw and has enough mana, interaction, or life support to make several activations worthwhile.
