No matches on the first button means this search found nothing listed under that price right now. The second button shows every current price.
What these searches leave out
Proxies, lots, code cards and other-language printings are excluded, and results are Buy It Now from US sellers, sorted by price plus shipping. Listings under $114.00 are left out because at that price they are almost always a different item. You can save either search on eBay to be emailed new matches.
The eBay buttons are affiliate links: if you buy after clicking, we may earn a commission at no extra cost to you. Wrong card or junk results? Report a problem.
Can it contain Origins: Proving Grounds's chase cards?
Yes: it holds Origins: Proving Grounds booster packs, and any Origins: Proving Grounds pack can hold one of the set's chase cards. Riot publishes no pull rates for them, so the site gives no odds.
Where to buy it
Retailers
No retailer product page for this Origins: Proving Grounds product could be verified on Oct 17, 2026: a page counts only when it was read and showed this exact product. Best Buy, GameStop and Walmart blocked the check that day. The site has no live retailer feed, so it lists none rather than guess a link, a price or stock.
