Teal Mask Ogerpon ex / Meganium / Arboliva ex deck: the core, the flex slots, and what beats it

What Teal Mask Ogerpon ex / Meganium / Arboliva ex looks like when you open the box

Across the 55 lists we counted, this deck runs 18 to 22 Pokémon, 26 to 32 Trainers and 10 to 14 Energy. Its attacks are paid for in Grass.

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

Look at the Energy: 10 to 14 out of 60, when half the 97 decks we track run 10 or fewer. This one carries more than most, and you feel it at the table — it wants to load up a big Pokémon and swing hard, even if that means drawing a spare Energy now and then.

It takes a while to set up. Arboliva ex is a Stage 2 Pokémon: you put down the baby, you evolve it, and then you evolve it again. Three cards stacked before anything attacks. That is what the hardest-hitting decks cost you, and it is also where they crack — a fast opponent can bury you before the line is standing.

Look at the Trainers: 26 to 32 cards out of 60, against a median of 31 across the 97 decks we track. Inside that, 7 to 14 Supporters, and the rule there is strict — one a turn, even if you are holding three. The 11 to 17 Items you can play all of in the same turn. It also brings up to 4 Stadiums, and 57 of the 97 decks we track bring that many or more. Only one Stadium sits on the table at a time: the one you play sends the one already there to the discard pile.

What Tools and Stadiums do — the two Trainer families we skipped here — and why the Energy count says so much: how to read a deck list.

What the cards in this deck's name actually do

Teal Mask Ogerpon ex, Meganium and Arboliva ex give this deck its name. Here is what is written on them.

Teal Mask Ogerpon ex is in all 55 lists, 4 copies of it. Its Ability is called Teal Dance, and here is what is printed on it, word for word: « Once during your turn, you may attach a Basic {G} Energy card from your hand to this Pokémon. If you attached Energy to a Pokémon in this way, draw a card. »

Meganium is in all 55 lists, 2 copies of it. Its Ability is called Wild Growth, and here is what is printed on it, word for word: « Each Basic {G} Energy attached to all of your Pokémon provides {G}{G} Energy. The effect of Wild Growth doesn't stack. »

Arboliva ex is in all 55 lists, 2 copies of it. Its attack Oil Salvo costs 1 Energy (Grass) and has no damage number printed next to it. That is why you will not find it in the attacker table lower down, which sorts by printed damage. Everything it does lives in its text: « Choose 1 of your opponent's Pokémon 6 times. (You can choose the same Pokémon more than once.) For each time you chose a Pokémon, do 20 damage to it. This damage isn't affected by Weakness or Resistance. »

How Teal Mask Ogerpon ex / Meganium / Arboliva ex actually wins

Arboliva ex attacks with Aroma Shot for 160. It needs 3 Colorless Energy attached, and it has 310 HP. And the number is not everything the card says. There is one more line printed under the attack, and it is the one everybody skips: "This Pokémon recovers from all Special Conditions."

The cost of Aroma Shot decides your first few turns. You only get to attach one Energy a turn, and that attack asks for 3. On your own attachments alone, your first real swing lands on turn 3. Except you are not on your own. Teal Mask Ogerpon ex, which the list runs 4 of, has an Ability called Teal Dance: it attaches Energy from your hand on top of the one you already play. An Ability costs you nothing: not your attack, not your card for the turn. That is where this deck buys its turns, and it is the first thing to look for in your opening hand.

Energy is not your only clock. Smoliv has to climb two steps before it becomes Arboliva ex, and an evolution asleep at the bottom of your deck does you no good at all. The list has that covered. Dawn, which the list runs 2 of, goes into your deck for an evolution.

Here is the detail that quietly loses games. To pull Arboliva ex back to the Bench you have to discard 2 Energy attached to it. Retreating does not cost you your turn, you can step back and still swing right after. What it costs you is the 2 Energy you spent 2 turns attaching, and you start that climb again from nothing. Pack a card that moves it for free, or send it up knowing it stays up.

Teal Mask Ogerpon ex, Arboliva ex and Fezandipiti ex carry the "ex" suffix, and your opponent takes 2 Prize cards instead of one when one of them falls. They need 6 to win: 3 well-placed knockouts on those cards beat you, where it would take 6 anywhere else on your Bench.

The core: the 15 cards every list runs

These 15 cards appear in all 55 lists, without a single exception. That is 49 of the 60 slots. The other 11 are decided player by player.

Look at how those 49 slots break down: 21 Trainers, 15 Pokémon, 13 Energy. Nothing stands out in that split. What sets this deck apart is how thick its core is: 49 of the 60 slots are the same for everybody, when half the 97 decks we track fix 34 or fewer. Fewer choices left to you than usual, and fewer ways to get them wrong.

8 of those 15 cards do not sit at the same count from list to list: Teal Mask Ogerpon ex (3 to 4), Forest of Vitality (2 to 4) and Lillie's Determination (3 to 4), plus 5 more. Add those spreads up and you get 14 copies the 55 lists do not agree on, inside the core itself.

What "3 to 4" means in the copies column, what the "TWM 130" code under each name is for, and why we count dozens of lists instead of one: how to read a deck list.

The 26 cards that change from list to list

26 cards fight over the 11 slots that are left: 8 above three lists in four, 15 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Meowth ex at 98 %, Unfair Stamp at 98 % and Night Stretcher at 96 %, plus 5 more above 75 %. Add those to the core and you have the common build.

The dividing line runs through Ciphermaniac's Codebreaking, at 45 %: 25 of 55 players took it, 30 put something else there. The ones who run it bring 1 copy. Right at the bottom of the table, Special Red Card (14 lists out of 55) and Hoothoot (13 lists out of 55).

Why a card at 45 % is not a bad card, and what order to buy all this in: how to read a deck list.

The most common Teal Mask Ogerpon ex / Meganium / Arboliva ex list, all 60 cards

Here they are in full, ready to build. 49 slots come from the core, the cards all 55 lists run. The remaining 11 come from the table just above, working down it: the cards the most players chose, each at its most common copy count, until the total lands on 60.

This list is nobody's list in particular. It takes, slot by slot, what the most people played, under the guardrails a judge would hold you to: never more than four copies of a card, and one ACE SPEC. Behind the core it took 9 more cards to reach 60. The whole thing comes to 20 Pokémon, 27 Trainers and 13 Energy.

One thing to know before you build it: the 55 lists we counted are all from players who came in the top twenty of their tournament. Nobody publishes the lists of the players who lost. So what you have in front of you is what the players finishing near the top bring most often.

The text under the table is the one the game expects: copy it, paste it into the deck manager, and the list builds itself.

There is no price total on this page. The readings we have are Cardmarket's, in euros, and the shop link further down sends you to TCGplayer, which quotes in dollars. Putting a euro figure next to a dollar shop would be one currency too many. The French and German pages carry the total.

Which decks beat Teal Mask Ogerpon ex / Meganium / Arboliva ex at tournaments

Here is how Teal Mask Ogerpon ex / Meganium / Arboliva ex did against every other deck at tournaments. Real games, real players sitting across the table from each other, and the platform those tournaments run on counts them one by one. All of them were played after Pitch Black became legal for tournaments, and we read the table on 5 September 2026.

The format matters more than people think. When the next set lands, decks get rebuilt around the new cards, and a matchup that leaned one way can swing the other. What you are reading holds for today's format.

We start with the opponent that gives you the most trouble, because that is where the work is before your next tournament. The further down the list you go, the better it goes for you.

Always look at the number of games next to the score. Six wins out of ten happens on its own, even with a middling deck: it is the same as flipping six heads in ten tries. Six hundred out of a thousand, and luck has nothing to do with it. Below 100 games we show nothing at all, because at that count half the matchups look like they lean one way when they lean nowhere.

Against Dragapult ex: over 111 games, 45 won and 65 lost. One ended with no winner.

Against Mega Excadrill ex: over 101 games, 63 won and 37 lost. One ended with no winner.

What Teal Mask Ogerpon ex / Meganium / Arboliva ex costs to build, and how long it will last

You need 41 different cards to cover every version of this deck, 15 of which nobody argues about. We do not have card prices, so we are not going to put a number on it.

All 55 lists bring an ACE SPEC, and that is where they part ways: 54 took Unfair Stamp and 1 took Scoop Up Cyclone. You are allowed ONE ACE SPEC card in your whole deck, so a single copy covers it whatever it costs. New to this deck? Take Unfair Stamp and watch what the others do with theirs before you switch.

Then there is time. 3 of the 15 core cards carry the letter H, the one that goes at the next rotation: Teal Mask Ogerpon ex, Fezandipiti ex and Bug Catching Set. The core table marks every one of them. In copies, that is 9 of the 49 slots the core fills. Which day it lands, we do not know yet.

What Teal Mask Ogerpon ex / Meganium / Arboliva ex struggles against

The attackers in this deck are Weak to Fire, so they take DOUBLE damage from that type. 10 of the 97 decks we track attack in exactly that type.

Concretely, here is what is waiting for you: Dragapult ex / Blaziken ex, Ethan's Typhlosion and Ceruledge ex, plus 7 more decks. The table below takes them one at a time, and those are the lists you practise against first before an event.

This table counts one thing, Weakness, and that comes to 10 decks out of the 97 we track. The other 87 do not attack into yours, and this table says nothing about them. You will still run into them.

Going the other way, your attackers are Grass, and 18 of the decks we track have an attacker Weak to one of those: N's Zoroark ex, Marnie's Grimmsnarl ex / Froslass and Mega Lucario ex, among others. That is you doubling, for once. Second half of the table.
