How to build a Pokémon TCG master set
Building a master set is one of the most satisfying things in the hobby… and also where most people get stuck. This guide covers what counts as a master set, the mistake that forces you to re-sort your whole binder, where to place reverse holos, and how to build it step by step without losing your mind.
What exactly is a master set?
«Master set» isn't an official Pokémon term — every collector uses their own — and that ambiguity is the first source of confusion. In practice there are three levels:
- Complete: Just the officially numbered cards (e.g. in Scarlet & Violet base, cards 1–198). The «playable» set.
- Master: Adds the secret rares (numbers above the printed total) and the reverse holo variant of every common, uncommon and rare. This is where the count explodes: a 198-card set can pass 400 slots.
- Grandmaster: Plus the promos tied to the set (Trainer Gallery, Shiny Vault, etc.), where they exist. The «everything».
The key point: decide your level before you start. Most of the frustration comes from starting without knowing what shape the finished binder will take.
Mistake #1: the cascading re-sort
It's the problem almost everyone hits. You slot cards in number order, miscount or land a card you were missing, and suddenly you have to shift every following card over one pocket. In a master set that means pulling out half the binder.
The fix is not to improvise: plan the whole layout before you slot the first card. The easiest way is to print a placeholder for every slot — a real-size box with the number and card — so each pocket already knows which card goes there. When you get the real card, you slot it in over the placeholder. Zero re-sorting.
Where do the reverse holos go?
It's the eternal debate, and there's no consensus. Two schools: (1) each reverse right behind its base card, keeping numeric order but doubling the depth; (2) a separate reverse section. Neither is perfect, because the reverse subset is smaller and more irregular than the base set. What matters is to decide up front and leave the gap — if you improvise, you end up re-sorting (see above). A good trick: note which cards have a reverse before you start, to reserve the space.
Secret rares and promos
Secret rares (numbers above the printed total) go at the end of the set, in order. Promos are the trickiest: they have no number within the set and sometimes drop after you thought it was complete. If you're going for Grandmaster, leave some slack pages at the end for promos that may appear.
9-pocket or 12: which do I pick?
The 9-pocket (3×3) is the standard and what almost everyone uses; it lines up nicely with number order. The 12-pocket (3×4) fits more per page and makes the binder more compact, but breaks the visual alignment of the opening pages. Rule of thumb: if it's your first master set, go 9-pocket. Switching format halfway means taking the whole thing apart.
What gear you need
Less than you'd think: a quality 9-pocket binder (Vault X, Ultra Pro Pro-Binder), standard 63 × 88 mm sleeves, and a normal printer for the placeholders. No cardstock or colour ink needed.

How to build it, step by step
Pick the set and level
Open the set page and choose the level: Complete, Master or Grandmaster. You'll see the exact slot count instantly.
Print the placeholders
Download the PDF and print it on A4 at 100% scale. Each slot comes out as a faded placeholder with number and name. To save ink, turn on low-ink mode.
Build it all at once, no cards
Cut along the marks and place all the placeholders in the binder. Now you have the full map of the set: each pocket already knows which card goes there, and you never re-sort again.
Slot cards in as you go
When you get a card, put it in its pocket over the placeholder. At a glance you see what you have and what you're missing.
Print only what you're missing
Mark the cards you already own on the site (Shift-click marks whole ranges) and turn on «Only what I'm missing»: the next PDF comes out with just the remaining slots.
Frequently asked questions
How many cards are in a master set?▾
It depends on the set and the level. A base set of ~198 cards can top 400 in Master mode once you add reverse holos and secret rares. Each set page gives you the exact count for the level you choose.
Do reverse holos count towards the master set?▾
Yes. The most accepted master-set definition includes the reverse holo variant of every common, uncommon and rare, plus the secret rares. Promos fall under the Grandmaster level.
Are placeholders worth it?▾
For a master set, absolutely: they save you from the cascading re-sort (the mistake that forces you to take half the binder apart) because you plan the whole layout before slotting the first card.
