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 24 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 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. 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.

Look at the Trainers: 26 to 35 cards out of 60, against a median of 31 across the 97 decks we track. Inside that, 7 to 13 Supporters, and the rule there is strict — one a turn, even if you are holding three. The 11 to 22 Items you can play all of in the same turn. It also brings up to 5 Stadiums, and 8 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 and Meganium give this deck its name. Here is what is written on them.

Teal Mask Ogerpon ex is in all 24 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 24 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. It needs 4 Energy, 2 Grass and 2 Colorless attached, and it has 160 HP.

The cost of Solar Beam decides your first few turns. You only get to attach one Energy a turn, and that attack asks for 4. On your own attachments alone, your first real swing lands on turn 4. 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. Chikorita has to climb two steps before it becomes Meganium, and an evolution asleep at the bottom of your deck does you no good at all. The list has that covered. Dawn, a single copy in the list, goes into your deck for an evolution. Careful, though: only 22 of the 24 lists bring it, so it is a choice, and players are still arguing about it.

Here is the detail that quietly loses games. To pull Meganium 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 carries the "ex" suffix, and your opponent takes 2 Prize cards instead of one when Teal Mask Ogerpon ex falls. They need 6 to win: 3 well-placed knockouts on that card beat you, where it would take 6 anywhere else on your Bench.

The core: the 6 cards every list runs

These 6 cards appear in all 24 lists, without a single exception. That is 26 of the 60 slots. The other 34 are decided player by player.

Look at how those 26 slots break down: 9 Trainers, 6 Pokémon, 11 Energy. Nothing stands out in that split. What sets this deck apart is how thick its core is: 26 of the 60 slots are the same for everybody, when half the 97 decks we track fix 34 or more. This one leaves more room than most, and two players can build it very differently.

5 of those 6 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. Add those spreads up and you get 15 copies the 24 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 89 cards that change from list to list

89 cards fight over the 34 slots that are left: 8 above three lists in four, 64 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Bayleef at 96 %, Bug Catching Set at 96 % 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 Team Rocket's Petrel, at 50 %: 12 of 24 players took it, 12 put something else there. The ones who run it bring 1 copy. Right at the bottom of the table, Unfair Stamp (6 lists out of 24) and Noctowl (5 lists out of 24).

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. 26 slots come from the core, the cards all 24 lists run. The remaining 34 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 19 more cards to reach 60. The whole thing comes to 18 Pokémon, 31 Trainers and 11 Energy.

One thing to know before you build it: the 24 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.

One thing to fix before you play: there is no ACE SPEC card in these 60. Players split that slot so many ways that none of their cards climbed high enough to get in, and 24 of the 24 lists carry one. Take Sparkling Crystal, the most chosen, and drop a card from the bottom of the table to make room.

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.

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

You need 95 different cards to cover every version of this deck, 6 of which nobody argues about. We do not have card prices, so we are not going to put a number on it.

All 24 lists bring an ACE SPEC, and that is where they part ways: 8 took Sparkling Crystal, 6 took Unfair Stamp and 3 took Hero's Cape. The flex table shows you all 8. 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. 1 of the 6 core cards carries the letter H, the one that goes at the next rotation: Teal Mask Ogerpon ex. The core table marks it. In copies, that is 4 of the 26 slots the core fills. Which day it lands, we do not know yet.

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. 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.
