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

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

Across the 20 lists we counted, this deck runs 13 to 21 Pokémon, 26 to 35 Trainers and 10 to 16 Energy. Its attacks are paid for in Grass.

On results pages and on stream you will see it written « ogerpon-meganium ». 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 16 out of 60, when half the 72 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. Meganium 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.

On the Trainer side: 7 to 12 Supporters, 11 to 22 Items, 0 to 1 Tools and 1 to 4 Stadiums, out of 26 to 35 — the median across the 72 decks we track being 31. Items dominate, so expect long turns where you chain five or six before you swing. And it runs up to 4 Stadiums, which is no accident: it plans on bumping the one across the table.

What those four families of Trainer actually do, 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 and Meganium give this deck its name. Here is what is written on them.

Teal Mask Ogerpon ex is in all 20 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 20 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. »

How Teal Mask Ogerpon ex / Meganium actually wins

Meganium attacks with Solar Beam for 140, and it costs 4 Energy (Grass, Grass, Colorless and Colorless), with 160 HP to absorb the answer. The whole list exists to get it online fast.

Do the arithmetic, it decides your first few turns. One Energy attached a turn, 4 to pay for Solar Beam: with no help you swing on turn 4, and every card that accelerates Energy buys one of those turns back.

Here is the detail that quietly loses games: Meganium has a Retreat Cost of 2, which is a whole turn to get it back to the Bench.

Teal Mask Ogerpon ex carries the "ex" suffix, and your opponent takes TWO Prize cards instead of one when Teal Mask Ogerpon ex falls. They need six to win: three well-placed knockouts on that card beat you, where it would take six anywhere else on your Bench.

The core: the 7 cards every list runs

These 7 cards appear in all 20 lists, without a single exception. That is 30 of the 60 slots. The other 30 are decided player by player.

Look at how those 30 slots break down: 13 Trainers, 6 Pokémon, 11 Energy. The balance is a normal one, so it is the cards themselves, more than the split, that give this deck its character.

5 of those 7 cards do not sit at the same count from list to list: Teal Mask Ogerpon ex (3 to 4), Lillie's Determination (2 to 4) and Forest of Vitality (1 to 4), plus 2 more. Everybody runs them, the last copy is arguable.

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 80 cards that change from list to list

80 cards fight over the 30 slots that are left: 7 above three lists in four, 59 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Bayleef at 95 %, Dawn at 95 % and Night Stretcher at 95 %, plus 4 more above 75 %. Add those to the core and you have the common build.

The dividing line runs through Poké Pad, at 50 %: 10 of 20 players took it, 10 put something else there. Read its text before you decide. Right at the bottom, Budew at 25 % and Special Red Card at 25 %: personal ideas, only worth copying if you know why.

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 list, all 60 cards

Here they are in full, ready to build. 30 slots come from the core, the cards all 20 lists run. The remaining 30 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 same guardrails a judge would hold you to: four copies of a card at most, one ACE SPEC, and a split that stays inside what these 20 lists actually showed. It comes to 18 Pokémon, 31 Trainers and 11 Energy.

A word on what it measures, because it changes what you can expect from it. The lists we read are the ones from players who came in the top twenty of their tournament. So there is no losing list to hold up against them, and "the cards that win" is not a sentence this count knows how to write. What you have in front of you is what the players finishing near the top bring most often. Start there.

The text under the table is the one the game expects. Copy it, open the deck manager, paste, and the list builds itself. Names in there are in English, with the set code and collector number right beside them: that pair points at one card and one only, whatever language you play in.

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.

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

You need 87 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.

Where the money goes, though, we can name: it is Teal Mask Ogerpon ex, by a distance. The 13 Trainer slots in the core cost next to nothing, and you probably own some already. All 20 lists bring an ACE SPEC, and that is where they part ways: 8 took Sparkling Crystal, 4 took Unfair Stamp and 3 took Hero's Cape. The flex table shows you all 7. 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 Sparkling Crystal and watch what the others do with theirs before you switch.

Then there is time. 2 of the 7 core cards carry the letter H, the one that goes at the next rotation: Teal Mask Ogerpon ex and Bug Catching Set. The core table marks each of them. The date belongs to the publisher, and we do not have it.

What Teal Mask Ogerpon ex / Meganium struggles against

The attackers in this deck are Weak to Fire, so they take DOUBLE damage from that type. 6 of the 72 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 3 more decks. The table below takes them one at a time, and those are the lists you practise against first before an event.

Do not stop at this table, though. This deck spends three cards getting Meganium standing, and the deck that hurts you most this season may simply be the one that swings before your line is up, without ever touching your Weakness.

Going the other way, your attackers are Grass, and 16 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.
