A set is never one number. One collector wants each number once, another wants every reverse holo too, and a third also wants the promos and stamps. TCGHeart tracks all three separately.
Base set is one card per numbered slot in the main set. Master set is everything you can pull from a pack, so reverse holos, ball patterns and secret rares included. Grandmaster adds everything you cannot pull from a pack: cosmos holos, non-holos, promos and stamps.
Each level sits inside the next, so you never see a base set fuller than your master set.
Alongside how many cards you are missing, you see what those cards currently cost. That turns a choice between two sets into a concrete one: not which is closest, but which is cheapest to finish.
You can also export the missing cards as a list to take to a fair.
Bought a set complete? Add everything you were missing in one action, at the level you choose.
Selling a set in one go works the same way, and you can choose between deleting it outright or recording it as sold with the proceeds.
A master set is everything that can come out of a pack, including reverse holos and secret rares. Grandmaster is that plus everything that cannot: cosmos holos, non-holos, promos, stamps and special releases.
No. Cards numbered beyond the set total, such as 095/094, belong to the master set rather than the base set.
English, Japanese and Chinese sets. You can filter the set list by language and track your progress per language.
Yes. You pick the level and the condition, and the app only adds what you did not already have.
