Mega Latias ex

What Mega Latias ex looks like when you open the box

Across the 8 lists we counted, this deck runs 10 to 17 Pokémon, 30 to 36 Trainers and 11 to 15 Energy. Its attacks are paid for in Psychic, Fire and Water.

On results pages and on stream you will see it written « mega-latias-ex ». 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: 11 to 15 out of 60, when half the 117 decks we track run 11 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.

Nothing here needs evolving — everything that attacks is a Basic Pokémon. Put it down, charge it, swing. That is as fast as the game gets, and it makes those turns where you draw nothing far less painful.

Look at the Trainers: 30 to 36 cards out of 60, against a median of 31 across the 117 decks we track. Inside that, 11 to 19 Supporters, and the rule there is strict — one a turn, even if you are holding three. The 10 to 18 Items you can play all of in the same turn. It also brings up to 3 Stadiums, and 110 of the 117 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.

How Mega Latias ex actually wins

Mega Latias ex attacks with Illusory Impulse for 300. It needs 3 Energy, 1 Fire, 1 Psychic and 1 Colorless attached, and it has 280 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: "Discard all Energy from this Pokémon."

The cost of Illusory Impulse 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. Crispin, which the list runs 3 of, looks at the top of your deck and attaches the Energy it finds there. Ethan's Ho-Oh ex does the same job. That is where this deck buys its turns, and it is the first thing to look for in your opening hand.

Good news on mobility: pulling Mega Latias 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 Latias 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 7 cards every list runs

These 7 cards appear in all 8 lists, without a single exception. That is 28 of the 60 slots. The other 32 are decided player by player.

Look at how those 28 slots break down: 10 Trainers, 4 Pokémon, 14 Energy. Nothing stands out in that split. What sets this deck apart is how thick its core is: 28 of the 60 slots are the same for everybody, when half the 117 decks we track fix 30 or more. This one leaves more room than most, and two players can build it very differently.

7 of those 7 cards do not sit at the same count from list to list: Latios (1 to 3), Mega Latias ex (2 to 3) and Lillie's Determination (3 to 4), plus 4 more. Add those spreads up and you get 16 copies the 8 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 69 cards that change from list to list

69 cards fight over the 32 slots that are left: 5 above three lists in four, 47 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Latias ex at 88 %, Mega Kangaskhan ex at 75 % and Ultra Ball at 75 %, plus 2 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 %: 4 of 8 players took it, 4 put something else there. The ones who run it bring 3 copies. Right at the bottom of the table, Lillie's Clefairy ex (2 lists out of 8) and Moltres (2 lists out of 8).

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 Latias ex list, all 60 cards

Here they are in full, ready to build. 28 slots come from the core, the cards all 8 lists run. The remaining 32 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 16 more cards to reach 60. The whole thing comes to 15 Pokémon, 31 Trainers and 14 Energy.

One thing to know before you build it: the 8 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 8 of the 8 lists carry one. Take Maximum Belt, 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. Our readings are in euros, taken on the European market, and that is not the currency you pay in. A figure you would have to convert in your head is worse than no figure at all. The French and German pages carry the total.

Why we only read lists from players who came in the top twenty of their tournament, and what that changes about every percentage on this page: how to read a deck list.

What Mega Latias ex costs to build, and how long it will last

You need 76 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.

All 8 lists bring an ACE SPEC, and that is where they part ways: 3 took Maximum Belt, 3 took Precious Trolley and 1 took Energy Search Pro. 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 Maximum Belt and watch what the others do with theirs before you switch.

Then there is time. 1 of the 7 core cards carries the letter H, the one that goes at the next rotation: Crispin. The core table marks it. In copies, that is 3 of the 28 slots the core fills. Which day it lands, we do not know yet.

What Mega Latias ex struggles against

The attackers in this deck have no printed Weakness at all. That is rare and it is worth a fortune: nobody gets to double the damage they put on you.

Nothing to show here today, and that is information in itself: none of the 117 decks we track carry the type that would double the damage you take.

Going the other way, none of the 117 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.
