Open the right boxes
Find +EV sealed product to flip
Most sealed buyers chase hype sets and lose money. The +EV approach: ignore the box on the cover, read the math, and only open product where the average pull beats the market price by a margin big enough to absorb time, taxes, and singles liquidity. SpellBook makes this calculation explicit so you can sort by it.
- Step 1
Start at EV Rankings, sort by EV ratio
EV ratio is expected pull value divided by box cost. A 1.0 ratio breaks even before fees. A 1.3+ ratio is meaningfully positive. Sort descending, filter to box types you can actually buy.

Check the singles backing the EV
Click into the top boxes. The breakdown shows which cards drive the EV. If 80% of the value comes from one mythic, you are really betting on that card's price holding. Diversified EV across 10+ cards is safer than concentrated EV.
- Step 3
Stress-test with Pack EV and the Simulator
Pack EV shows the per-pack distribution: not just average, but the chance you crack a $50 pack vs. a $3 pack. Box Simulator runs Monte Carlo opens so you can see what a typical case actually looks like.

Cross-check the price source
EV uses fair-value pricing across multiple marketplaces, but TCGplayer market price is what you will actually clear at on resale. If the chase cards trade thin, discount the EV by 15-20% for liquidity risk.
- Step 5
Buy, open, list singles, track in your portfolio
Log the box buy as a portfolio entry so you can compare what you paid vs. what you pulled. The realized-vs-expected gap is the only honest measure of whether your sealed strategy is working.
