Wailord ex deck: the core, the flex slots, and what beats it

We took 20 lists of this deck and counted every card in every one of them. They come from 18 different tournaments, built by 20 people who never talked to each other. What all of them run is the core of the deck: 7 cards, 31 slots out of 60. The rest — 61 cards fighting over what is left — is where players disagree, and that is usually where a game is won.

Published Data updated
THE SHORT VERSION
  • 7 cards show up in all 20 lists we counted. No exceptions. That is 31 of your 60 slots. If you are building this deck, start there — nobody argues about those.
  • Your big card is Wailord ex, 380 HP. Falling Down hits for 270, and it costs you 5 Energy (Water, Water, Water, Water and Water).
  • 61 cards change from list to list. That is exactly where a good player tunes the deck for what they expect to face, and the table below tells you how many lists run each one.
  • This deck has a Weakness printed right on its cards: Lightning. 1 of the decks we track attack in exactly that type. They are listed at the bottom, with the card that does the damage.

What this deck looks like when you open the box

Across the 20 lists we counted, this deck runs 10 to 20 Pokémon, 28 to 39 Trainers and 11 to 14 Energy. Its attacks are paid for in Water.

On results pages and on stream you will see it written « wailord-ex-pbl ». Every card named in that label turns up in the tables below, which is what makes it a fair name for the deck.

The bit they tack on the end, « PBL », is a set code: Pitch Black. They spell it out because several cards share that name, and this deck plays that particular printing.

Look at the Energy count first: 11 to 14 out of 60. No single number tells you more about how a deck breathes. A lot of Energy means it wants to load up one big Pokémon and swing hard. Very little means it lives on cheap attacks and on Trainers to dig out whatever it is missing.

It sets up fast. Wailord ex is a Stage 1 Pokémon: a Basic, one evolution on top, and you are attacking. Two cards instead of three. You lose fewer turns building, and you rebuild much more easily when an early knockout lands on you.

On the Trainer side: 10 to 16 Supporters, 8 to 22 Items, 2 to 4 Tools and 0 to 3 Stadiums. Worth saying out loud, because everyone forgets it once a tournament: you only get ONE Supporter a turn, while you can chain as many Items as you like. So a deck full of Items takes longer, louder turns than a deck full of Supporters.

A range means the lists disagree with each other.

How it actually wins

Wailord ex attacks with Falling Down for 270, and it costs 5 Energy (Water, Water, Water, Water and Water). It has 380 HP to absorb the answer. Everything else in the list is built around getting that card online.

Do the arithmetic with us, because it decides your first few turns. You attach one Energy a turn by hand. Wailord ex wants 5. With no help, that means you swing on turn 5 at the earliest. Every card in this deck that accelerates Energy or fetches a Pokémon buys back a turn on that count, and at this level a turn is a game.

Here is the detail that quietly loses games: Wailord ex has a Retreat Cost of 4. Once it is in the Active spot you are not getting it back to the Bench cheaply. Think before you send it up.

1 of the core Pokémon carry the « ex » suffix. Those are the big ones: high HP, attacks that hurt, and the price tag to match. They also cost you more when they fall — an opponent takes extra Prize cards for knocking out an ex, so every trade you lose there walks you towards the loss faster than you think.

The core: the 7 cards every list runs

These 7 cards appear in all 20 lists, without a single exception. That is 31 of the 60 slots. The other 29 are decided player by player.

This is the most useful table on the page, and nobody publishes it. Everywhere else you get one list, from one player, who won one tournament. Fine — but you have no way of telling which parts of it were the deck and which parts were that person's idea on the day. Counting 20 lists settles the question by itself: what 20 people put in their deck without talking to each other IS the deck.

A word on the count column. We give you the number that comes up most often, and where the lists disagree we give you the range instead. A card sitting at "3 to 4" is one everybody plays but whose fourth copy is up for debate. That is exactly the kind of slot you reclaim when you want to fit an idea of your own.

The code next to the name — "TWM 130" and the like — is the set and the collector number, printed at the bottom of the card. We show you the printing the lists use most often, because two cards can share a name and have completely different attacks. Check that number before you buy anything.

What changes from one list to the next

61 cards show up in some lists and not in others. The percentage tells you how many lists run each one: at 50%, half the players want it and the other half deliberately chose something else.

Do not read this table as a ranking from best to worst. A card sitting at 80% is one four players in five find useful and the fifth cut on purpose, usually because they were expecting a different field. That disagreement is worth something on its own.

Here is how to use it when you build. Take the whole core first, no arguing. Then walk down this list and stop on every card you do not understand: read its text, work out what it is answering. A card you cannot explain is a card you will misplay, even if the champion had it in their list.

And if this is your first time with the deck, build the boring version — the full core plus the most common cards from here. Understand the deck before you start tinkering with it. That order is the only one that works.

What it costs to build, and how long it will last

You need 68 different cards to cover every version of this deck, 7 of which nobody argues about. We do not have card prices, so we are not going to put a number on it.

What we can tell you is where the money goes. 1 ex Pokémon in the core, and they are almost the whole bill. The Trainers and basic Energy are near enough free, or already in your box. This deck runs no ACE SPEC card at all.

And here is a genuinely good piece of news: not one core card carries the letter H, the one that goes at the next rotation. This deck walks through the change with its skeleton intact. At equal price, that is the argument that should settle it.

One last piece of old-player advice. Never build a deck card by card starting with the prettiest one. Start with the core Trainers: they are cheap, they carry over into other decks, and they are what keeps the deck running. Buy the expensive Pokémon last, once you know you actually enjoy the deck.

What this deck struggles against

The attackers in this deck are Weak to Lightning. A card with a Weakness takes DOUBLE damage from an attacker of that type. Of the decks we track, 1 attack in exactly that type.

Here is how the table below is built. The Weakness is printed on your cards, the type of the attacker across the table is printed on theirs, and the fact that this particular deck really does play that attacker is counted off its own lists. You can check every line of it with the cards in your hand.

One limit, while we are here. Weakness alone does not decide a match. A deck can double your damage and still lose because it sets up too slowly, or crush you without ever touching your Weakness. This table tells you where to look first. What settles the game sits further along.

Going the other way, your attackers are Water — and 7 of the decks we track have an attacker Weak to one of those. That is you doubling, for once. Second half of the table.

Questions people ask

What is the Wailord ex deck list?
There isn't one, and that is the whole point. Across 20 tournament lists harvested on 11 August 2026, 7 cards turn up in every single one — 31 slots out of 60. The remaining 29 change from player to player, with 61 different cards competing for them. Both tables are above.
How many lists is this counted on, and where do they come from?
20 lists, played across 18 different tournaments, harvested on 11 August 2026 from play.limitlesstcg.com. Every one of them was read card by card, and every card was recognised.
Where do I start if I want to build this deck?
With the whole core: 7 cards, 31 slots. Inside that core, buy the Trainers and Energy first — they are cheap and they carry over into other decks — and leave the 1 ex Pokémon for last, because they are the bill. Only then work down the flex table and add the cards the most lists agree on.
What beats this deck?
Its attackers are Weak to Lightning, so they take double damage from an attacker of that type. Of the decks we track, 1 play an attacker of that type: Mega Manectric ex / Eelektrik. One caveat. Weakness tells you where to look first. What settles the game sits further along.
Will this deck survive the next rotation?
Yes, and without losing anything. No core card carries the letter H, the one that goes at the next rotation. That is a real argument when you are deciding where to put your money.
Are these numbers current?
The lists were harvested on 11 August 2026, and the harvest runs every night. Every new list joins the count, so the percentages on this page move on their own as the format moves. When a card crosses over from the flex table into the core, that is the players moving first and the count following them.

Where all of this comes from

The 20 lists come from play.limitlesstcg.com, which publishes the decks played at official tournaments. They were harvested on 11 August 2026 across 18 different events, then read card by card against poko's own card catalogue (built from the public TCGdex API) to recover what each card actually does. Card prices appear nowhere on this page: we have no reading fresh enough, and an empty cell beats a stale number. The TCGplayer link in the cost section is a shop link. It is labelled as one right where it stands.

NOW YOUR OWN GAME

You've just read a page about the game. We can do far more with one match.

Everything above is about the game in general. The thing we're really good at is one single match: yours. When a game ends, Pokémon TCG Live leaves you a log — the written record of everything that happened, turn by turn. Paste it here and we'll replay each of your decisions hundreds of times, then tell you which one actually cost you the game.

It's free and there's no account to make. Your log stays in your browser: your browser is what replays the game.
