Corporate profile
MasterSets operates from a 42-story tower in downtown Chicago, shaped like a booster pack. Floors 1 through 41 are storage for bulk commons. Floor 42 is where the one good pull lives.
Over 12,000 employees in Chicago alone. 11,400 of them are sorting energy cards. They have been sorting since 2019. They are not close.
Offices in Tokyo, London, São Paulo, and a card shop parking lot in Ohio that we’re pretty sure counts.
MasterSets Lunar Division. Low gravity means no bent corners. Opening Q3, pending rocket.
To help every collector finish every master set. Including the one with 214 reverse holos. Yes, that one.
None of the above is true. The part below is.
Okay, for real
MasterSets is a free collection tracker for collectors who care about completing sets — every card, every variant, every rarity, across Pokémon, Magic: The Gathering, Lorcana, Star Wars Unlimited, Flesh and Blood and more. It is based in Chicago and supported by a network of collectors and contributors around the world, who help verify card data, track new releases, and shape how the platform grows.
The people behind MasterSets were kids once too, trading Panini stickers in the ’80s across France, England and Switzerland. Then they became parents and found themselves managing their kids’ collections alongside their own. MasterSets is the tool they wished they’d had.
It is free to use. Some links to eBay and TCGplayer are affiliate links: if you buy through them, MasterSets earns a small commission at no extra cost to you. That helps keep the servers on. The longer version of what this site will and won’t do is on Why MasterSets.
Pick a game, open a set, and mark what you own. No account needed to try it, and nothing to cancel if you don’t stay.
