Rip it or keep it

Rip it or keep it?

Is a sealed booster box worth more opened or kept? Every hit is priced from Cardmarket offers in the language you pick, refreshed every night or every few days depending on the game, so you can see what an average box is really worth before you open it.

How it works

  1. Every hit, priced in your languageEach valuable card is checked on Cardmarket with the filter for the language you picked (every night for Riftbound, every few days for the other games), using the middle of the three cheapest Near Mint offers in that language.
  2. Pull rates per boxPublished odds where the publisher has them, community box counts where it doesn't. You can change every rate.
  3. 20,000 boxes, opened on paperSimulated openings show what a typical box looks like and how often a box beats its price.

Ranked by return per box

Return is the expected value after the selling fee, compared with the box price. "Box beats price" is the share of 20,000 simulated boxes worth more than you paid. The bar shows expected value and the tick marks the box price.

Set

Where the value comes from

Pulls per box can be changed. Every card in a tier is assumed equally likely, so a tier is worth its pull rate times its average card value.
