Riot Games' Riftbound is making a big splash on the TCG market this week, thanks to a new release that quickly sold out and is going for nearly 20 times its asking price on the secondhand market. The Riftbound x T1 2025 Worlds Champion Signature Edition started shipping out to buyers over the past week, and many have since quickly been flipped on eBay, with some auctions fetching upward of $7,000.
