Four moves. One week.
A card on the line.
02 PICK
Lock in your Pick.
Every outcome shows its market probability, and the moment you submit, that number locks to your Pick. Hit, and you earn what the market doubted. Miss, and you give back what it believed. Rarer Picks score more.
03 CLIMB
Climb the Standings.
Every week has its own live Standings. Your Score is the average of your Picks, so volume never buys rank, and the top of the week takes the prizes.
04 COLLECT
Place. Win the card.
Top placements win graded collectibles. Keep yours in the Vault, ship it home, or take the Instant Cash Offer.
