How to build a deck that actually places
The rules take a minute to learn and are the same for everyone. What separates a deck that wins from one that does not is its shape — and that is measurable. Every ratio below comes from 2,408 decklists that finished top 8 across the 704 tournaments we track, measured 3 August 2026. Where the numbers contradict the usual advice, we went with the numbers.
The shape of a placing deck
8
Pokémon
12
Trainers
5
of which Basic
Medians, not targets. The headline is the ratio: Trainers outnumber Pokémon in most decks that place. Beginners almost always build the reverse, filling slots with Pokémon that never attack, and then lose to decks that draw into their win condition two turns sooner.
How many Basics, really
84% of placing lists run 4 to 6 Basics. The advice you will read everywhere — including, until today, on this site — is 6–10, a range that covers only 32% of them.
The reason is a rule people forget: your opening five cards are guaranteed to contain at least one Basic, and there is no mulligan. You are not insuring against a dead opening hand, because the game already does that. Past the sixth, extra Basics mostly turn into cards you draw instead of the ones you needed. Check the exact odds for your build.

Share of placing lists running at least one copy. The top three are effectively mandatory — they are how a 20-card deck finds its win condition before the opponent finds theirs. Build the consistency core first, then spend what is left on cards specific to your strategy.
Evolution lines
A Stage 2 attacker costs six slots at two copies per stage — nearly a third of the deck before a single Trainer. That is why 44% of placing lists run Rare Candy: skipping Stage 1 buys back two slots and a turn.
If your ace is a Basic, you are already ahead on tempo and can spend the difference on Trainers. Neither choice is wrong — but a Stage 2 deck with the Trainer count of a Basic deck is, because it will draw its evolutions and nothing to play them with.
Start from something that works
The fastest way to internalise these ratios is to open a deck that already has them. These are the most-played archetypes right now — the builder starts pre-seeded with each one’s key card and fills the rest around it.

How these numbers were measured
Every figure on this page comes from 2,408 decklists that finished in the top 8 of a competitive tournament, drawn from the 704 events in our database and measured on 3 August 2026. They describe what winning players did, not what any guide recommends — including this one, which used to recommend the opposite ratio. Structural ratios move slowly; the staple list shifts with each new set.
