How to start a set you can actually finish

Find the base run, decide what complete means, check the short prints, prefer a closed set, and match it to how you buy. Five things to settle first.

Completing a set is the oldest goal in the hobby and the one modern products are least built for. The checklists we hold run from 3 entries to 15,896, and whether a set is finishable is decided before you buy a single pack.

Five things to establish first. All of them are answerable from documents that already exist.

1. Find the base run, not the checklist total

The headline number counts every parallel finish as a separate card. The base run is the sequence of distinct photographs, and it is the only number describing something a person can complete. A checklist of 15,896 entries may rest on a base run of a few hundred.

The median set we hold is 798 entries, which is already large enough that the distinction decides the project.

2. Decide what counts as complete

Base set only, base plus inserts, or master set including every parallel. Write it down before you start, because the answer changes what you buy and the temptation to expand it arrives around the halfway mark.

The master set is not available to most people in most products. 109,315 of the cards we track are numbered to one, and a set whose top finishes are made once has a master set that exists on paper and not in a binder.

3. Check for short prints before committing

A set with a short printed subset at the end of its numbering is a different project from one without. We hold 1,212 entries flagged as short prints, and they cluster: a product tends either to have them or not.

Finding this out at card 280 of 300 is the expensive way to learn it.

4. Prefer a closed set to an open one

A product whose checklist is published in full and will not grow is a finishable project. One with redemptions outstanding, or a card count the manufacturer has not confirmed, has an end point nobody can state yet.

Our checklist pages say explicitly when a set total has not been confirmed, because that is the fact that decides whether finishing is even possible.

5. Match the set to how you actually buy

If you buy singles, a large base run is a long shopping list and nothing worse. If you buy boxes hoping to complete a set, almost any modern base run will cost more in boxes than in singles, and you will finish with a pile of duplicates. Boxes are a good way to open packs and a poor way to complete sets, and those are different hobbies that happen to share a shelf.

A reasonable first target

A base run of a few hundred cards, from a product already fully published, with no short prints and no outstanding redemptions, bought as singles. That is a project with a defined end, and the end is what makes it a set rather than an accumulation.

None of this is advice about what anything will be worth. It is about whether the thing you have decided to do can be done.

Frequently asked questions

How do I know how many cards are in a set?

Find the base run rather than the checklist total. The total usually counts every parallel finish separately.

Can you complete a master set?

Rarely. The top finishes in most modern products are made once, so a master set exists more on paper than in practice.

Are boxes a good way to complete a set?

Usually not. Most base runs cost more in boxes than in singles, and you finish with duplicates.
