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

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

Across the 21 lists we counted, this deck runs 13 to 19 Pokémon, 26 to 31 Trainers and 12 to 19 Energy. Its attacks are paid for in Grass.

On results pages and on stream you will see it written « sinistcha-ogerpon ». 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: 12 to 19 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 sets up fast. Sinistcha 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: 26 to 31 cards out of 60, against a median of 31 across the 97 decks we track. Inside that, 5 to 12 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

Sinistcha and Teal Mask Ogerpon ex give this deck its name. Here is what is written on them.

Sinistcha is in all 21 lists, 4 copies of it. Its attack Cursed Drop costs 1 Energy (Grass) and has no damage number printed next to it. That is why you will not find it in the attacker table lower down, which sorts by printed damage. Everything it does lives in its text: « Put 4 damage counters on your opponent's Pokémon in any way you like. »

Teal Mask Ogerpon ex is in all 21 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. »

How Sinistcha / Teal Mask Ogerpon ex actually wins

Sinistcha attacks with Spill the Tea. It needs 1 Grass Energy attached, and it has 70 HP. Watch the damage box. "70×" does not mean 70 damage: it means 70 per card you discard yourself to fire the attack. The total moves every turn.

One Energy to attack is enormous, and it means the attack cost will never be what slows you down. What slows you down here is getting Sinistcha up. Once the line is standing you swing every turn with nothing to recharge, and you can start again immediately when your attacker falls.

Good news on mobility: pulling Sinistcha 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.

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 7 cards every list runs

These 7 cards appear in all 21 lists, without a single exception. That is 38 of the 60 slots. The other 22 are decided player by player.

Look at how those 38 slots break down: 13 Trainers, 8 Pokémon, 17 Energy. Nothing stands out in that split. What sets this deck apart is how thick its core is: 38 of the 60 slots are the same for everybody, when half the 97 decks we track fix 34 or fewer. Fewer choices left to you than usual, and fewer ways to get them wrong.

5 of those 7 cards do not sit at the same count from list to list: Sinistcha (2 to 4), Teal Mask Ogerpon ex (3 to 4) and Boss's Orders (1 to 4), plus 2 more. Add those spreads up and you get 14 copies the 21 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 47 cards that change from list to list

47 cards fight over the 22 slots that are left: 3 above three lists in four, 31 below one in four, and the percentage on each row says how many players took it.

The most agreed on first: Sinistcha ex at 95 %, Poltchageist at 90 % and Prime Catcher at 81 %. Add those to the core and you have the common build.

The dividing line runs through Flutter Mane, at 52 %: 11 of 21 players took it, 10 put something else there. The ones who run it bring 1 copy. Right at the bottom of the table, Poltchageist (5 lists out of 21) and Pokégear 3.0 (5 lists out of 21).

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

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

You need 54 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 21 lists bring an ACE SPEC, and that is where they part ways: 17 took Prime Catcher, 3 took Unfair Stamp and 1 took Brilliant Blender. 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 Prime Catcher and watch what the others do with theirs before you switch.

Then there is time. 4 of the 7 core cards carry the letter H, the one that goes at the next rotation: Sinistcha, Teal Mask Ogerpon ex, Bug Catching Set and Night Stretcher. The core table marks every one of them. In copies, that is 14 of the 38 slots the core fills. Which day it lands, we do not know yet.

What Sinistcha / Teal Mask Ogerpon ex 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.

When an attack does nothing at all

There are two ways to hurt the Pokémon across the table, and the game does not treat them the same. An attack with a number printed next to it deals damage. An attack with no number, whose text just says "place 2 damage counters", does what the rules call an effect. That matters, because a handful of Pokémon have an Ability that prevents the effects of your opponent's attacks, and their card spells it out in brackets: damage is not an effect.

This deck has an answer to that. Poltchageist has Hide 'n' Sneak, and 19 lists out of 21 play it. Against an attack that only places counters, that Pokémon takes nothing at all. Not one counter. An attack with a number printed next to it still puts its damage on it, mind you. Careful, though: the Ability protects the card that has it, and only that card. The rest of your bench takes everything.

Of the decks we track right now, 4 play an attack like that. They are in the table below, with the Pokémon carrying it. When you run into one, put that Pokémon in the Active Spot: the marker attack can no longer touch it. Your opponent will have to reach for printed-damage attacks — most of these decks carry some too. The wall buys you turns, it does not win the game for you.

The other way round, this deck attacks with counters too: Sinistcha with Cursed Drop, Sinistcha ex with Re-Brew and Poltchageist with Furtive Drop. Those attacks have no damage number printed next to them at all. In front of a Pokémon that shuts off effects, they place nothing. Zero.

Of the decks we track, 6 play a Pokémon like that, and they are in the table below. The day you see one come across the table, stop counting on your counters. You need an attack with a real number written on it. You have one: Spill the Tea, on Sinistcha, for 70×.
