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

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

Across the 51 lists we counted, this deck runs 15 to 21 Pokémon, 32 to 38 Trainers and 6 to 8 Energy. Its attacks do not ask for any particular type of Energy.

On results pages and on stream you will see it written « lopunny-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: 6 to 8 out of 60, when half the 97 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.

Look at the Trainers: 32 to 38 cards out of 60, against a median of 31 across the 97 decks we track. Inside that, 10 to 16 Supporters, and the rule there is strict — one a turn, even if you are holding three. The 12 to 20 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

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

Mega Lopunny ex is in all 51 lists, 3 copies of it.

Dudunsparce is in all 51 lists, 3 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 Lopunny ex / Dudunsparce actually wins

Mega Lopunny ex attacks with Spiky Hopper for 160. It needs 2 Colorless Energy attached, and it has 330 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 attack's damage isn't affected by any effects on your opponent's Active Pokémon."

The cost of Spiky Hopper decides your first few turns. You only get to attach one Energy a turn, and that attack asks for 2. On your own attachments alone, your first real swing lands on turn 2. We have not found anything in this list that attaches Energy faster than that, so plan on holding out for a turn before you swing. Those turns still get played: you fill your Bench, you build your lines, and you keep something back to rebuild with when your attacker falls.

Energy is not your only clock. Dunsparce has to climb a step before it becomes Dudunsparce, and an evolution asleep at the bottom of your deck does you no good at all. The list has that covered. Hilda, which the list runs 4 of, goes into your deck for an evolution.

Good news on mobility: pulling Mega Lopunny ex back to the Bench costs you 1 Energy attached to it, and that is all. Retreating does not cost you your turn, so you step back and swing anyway. That matters enormously the day your opponent lands something nasty on it.

Mega Lopunny ex is a Mega Evolution ex, and that is the most expensive rule in the game: your opponent takes 3 Prize cards instead of one the turn it goes down. They need 6 to win the game, so 2 well-placed knockouts on that card beat you, where it would take 6 knockouts anywhere else on your Bench.

The core: the 9 cards every list runs

These 9 cards appear in all 51 lists, without a single exception. That is 29 of the 60 slots. The other 31 are decided player by player.

Look at how those 29 slots break down: 22 Trainers, 7 Pokémon, 0 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: Dudunsparce (2 to 4), Mega Lopunny ex (2 to 3) and Fan Rotom (1 to 2), plus 6 more. Add those spreads up and you get 15 copies the 51 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 62 cards that change from list to list

62 cards fight over the 31 slots that are left: 9 above three lists in four, 42 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Ultra Ball at 98 %, Battle Cage at 98 % and Mist Energy at 98 %, plus 6 more above 75 %. Add those to the core and you have the common build.

The dividing line runs through Moltres, at 53 %: 27 of 51 players took it, 24 put something else there. The ones who run it bring 1 copy. Right at the bottom of the table, Stunfisk (12 lists out of 51) and Prism Energy (12 lists out of 51).

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

Which decks beat Mega Lopunny ex / Dudunsparce at tournaments

Here is how Mega Lopunny ex / Dudunsparce 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 112 games, 59 won and 52 lost. One ended with no winner.

What Mega Lopunny ex / Dudunsparce costs to build, and how long it will last

You need 71 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.

All 51 lists bring an ACE SPEC, and that is where they part ways: 40 took Enriching Energy and 11 took Hero's Cape. 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 Enriching Energy and watch what the others do with theirs before you switch.

Then there is time. 3 of the 9 core cards carry the letter H, the one that goes at the next rotation: Dudunsparce, Fan Rotom and Buddy-Buddy Poffin. The core table marks every one of them. In copies, that is 8 of the 29 slots the core fills. Which day it lands, we do not know yet.

What Mega Lopunny ex / Dudunsparce struggles against

The attackers in this deck are Weak to Fighting and Lightning, so they take DOUBLE damage from those types. 17 of the 97 decks we track attack in exactly those types.

Concretely, here is what is waiting for you: Mega Lucario ex, Mega Lucario ex / Hariyama and Cynthia's Garchomp 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.

This table counts one thing, Weakness, and that comes to 17 decks out of the 97 we track. The other 80 do not attack into yours, and this table says nothing about them. You will still run into them.

Going the other way, none of the 97 decks we track have an attacker Weak to your types. So you are not going to win trades on Weakness — you will have to win them on raw damage.
