Yu-Gi-Oh prices on TCGIndex are TCGplayer market prices (the US market), in US dollars, with graded and sold prices from PriceCharting and eBay. Another currency is a conversion from USD at the day's rate, not a European market price. We do not use Cardmarket or Cardtrader prices for Yu-Gi-Oh.
We may earn a commission from qualifying purchases made through our eBay & TCGplayer links.
Every night the model scores every Yu-Gi-Oh! card on the market. Every morning at 07:30 UTC it publishes the one most likely to gain 10% within 30 days, with its entry price and the reasons, then scores it in public.
Last 90 days, live picks only, losses included.
