The Caesars Rewards Visa (Bread/Comenity) opens exactly one door: Caesars Rewards Platinum. There's no tier ladder to climb here — activate the card and make any purchase within the first 90 days of approval, and Caesars upgrades your account to Platinum within 30 days of that purchase. No spending threshold to hit, just first use. The card carries a $0 annual fee and is currently open to US applicants.
Where the card asks more is in keeping Platinum once you have it. Each subsequent calendar year, you need to charge $5,000 to the card to retain the status — miss that and the upgrade doesn't roll forward. So the first year is close to free, and every year after depends on that spend clearing.
