Mega Froslass ex / Dudunsparce deck: the core, the flex slots, and what beats it

What Mega Froslass ex / Dudunsparce looks like when you open the box

Across the 20 lists we counted, this deck runs 14 to 23 Pokémon, 29 to 39 Trainers and 5 to 10 Energy. Its attacks are paid for in Water.

On results pages and on stream you will see it written « mega-froslass-dudunsparce ». 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: 5 to 10 out of 60, when half the 72 decks we track run 10 or more. This one is lean. It lives on cheap attacks and leans on Trainers to find the right Energy at the right moment rather than stockpiling it.

It sets up fast. Dudunsparce 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: 9 to 18 Supporters, 10 to 22 Items, 0 to 3 Tools and 0 to 3 Stadiums, out of 29 to 39 — the median across the 72 decks we track being 31. Items edge it without crushing the Supporters. And it runs up to 3 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

Mega Froslass ex and Dudunsparce give this deck its name. Here is what is written on them.

Mega Froslass ex is in all 20 lists, 3 copies of it.

Dudunsparce is in all 20 lists, 2 copies of it. Its Ability is called Run Away Draw, and here is what is printed on it, word for word: « Once during your turn, you may draw 3 cards. If you drew any cards in this way, shuffle this Pokémon and all attached cards into your deck. »

How Mega Froslass ex / Dudunsparce actually wins

Mega Froslass ex attacks with Absolute Snow for 150, and it costs 3 Energy (Water, Colorless and Colorless), with 310 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, 3 to pay for Absolute Snow: with no help you swing on turn 3, and every card that accelerates Energy buys one of those turns back.

Good news on mobility: Mega Froslass ex retreats for 1 Energy. You can pull it out of the Active spot without throwing away your turn, and that matters enormously when your opponent lands something nasty on it.

Mega Froslass ex carries the "ex" suffix, and your opponent takes TWO Prize cards instead of one when Mega Froslass 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 9 cards every list runs

These 9 cards appear in all 20 lists, without a single exception. That is 27 of the 60 slots. The other 33 are decided player by player.

Look at how those 27 slots break down: 15 Trainers, 8 Pokémon, 4 Energy. Trainers outweigh everything else put together, which is the mark of a deck that goes and fetches its cards rather than waiting to draw them.

9 of those 9 cards do not sit at the same count from list to list: Mega Froslass ex (2 to 4), Snorunt (2 to 4) and Dudunsparce (2 to 4), plus 6 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 63 cards that change from list to list

63 cards fight over the 33 slots that are left: 7 above three lists in four, 40 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Pokégear 3.0 at 90 %, Wally's Compassion at 85 % and Night Stretcher at 85 %, plus 4 more above 75 %. Add those to the core and you have the common build.

The dividing line runs through Fire Energy, at 50 %: 10 of 20 players took it, 10 put something else there. Read its text before you decide. Right at the bottom, Shaymin at 25 % and Froslass at 20 %: 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 Mega Froslass ex / Dudunsparce list, all 60 cards

Here they are in full, ready to build. 27 slots come from the core, the cards all 20 lists run. The remaining 33 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 21 Pokémon, 33 Trainers and 6 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 Mega Froslass ex / Dudunsparce costs to build, and how long it will last

You need 72 different cards to cover every version of this deck, 9 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 Mega Froslass ex, by a distance. The 15 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: 17 took Hero's Cape, 1 took Legacy Energy and 1 took Scoop Up Cyclone. The flex table shows you all 4. 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 Hero's Cape and watch what the others do with theirs before you switch.

Then there is time. 2 of the 9 core cards carry the letter H, the one that goes at the next rotation: Dudunsparce and Buddy-Buddy Poffin. The core table marks each of them. The date belongs to the publisher, and we do not have it.

What Mega Froslass ex / Dudunsparce struggles against

The attackers in this deck are Weak to Metal and Fighting, so they take DOUBLE damage from those types. 17 of the 72 decks we track attack in exactly those types.

Concretely, here is what is waiting for you: Mega Excadrill ex, Slowking (Metagross) and Mega Lucario ex, plus 14 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 sets up fast, so what troubles it looks less like a Weakness and more like an opponent who absorbs your first hits and answers harder.

Going the other way, your attackers are Water, and 6 of the decks we track have an attacker Weak to one of those: Dragapult ex / Blaziken ex, Ethan's Typhlosion and Ceruledge ex, among others. That is you doubling, for once. Second half of the table.
