Alola Trainers! It’s been a whirlwind of a new metagame lately, with a couple of new contenders popping up in online tournaments. Mewtwo & Mew Tag Team GX (“Mewtwo”) has been bringing the heat in this recently newfound variant appropriately titled “Galaxy Mewtwo”! Galaxy Mewtwo is excellent at countering current threats in the standard format, as it specifically focuses around Psychic Energy but utilizes Aurora Energy to attack with different GX Pokémon. Many Pokémon in the format are Psychic-weak, but the biggest one just so happens to be Rapid Strike Urshifu VMAX. Rapid Strike just won the Player’s Cup 3 by the hands of Azul Garcia Griego, so you can expect that we’re going to see a ton of this deck in the future; since we can’t afford to consistently lose to one of the most common top tier decks, we need to ensure a victory against it (and that’s just what this deck does). The versatility and efficiency that Mewtwo as a deck carries is unmatched by any other deck since Mewtwo can collectively have over ten attacks to choose from in any given matchup! This is a spicy deck that’s been doing really well in today’s metagame, so let’s hop into why I love it so much!

I booted up my Pokémon Trading Card Game Online app, loaded up some PTCGO codes, and then traded those Pokémon TCG online codes to trade for this deck. I was very excited, and it honestly didn’t take that many PTCGO codes to make the deck. If you’re looking to buy some codes, we sell them here on PTCGO Store, and I highly urge you to check out our competitive pricing and swift delivery! Let’s talk about Mewtwo & Mew Tag Team GX today.

The best way to understand how a Mewtwo deck works is first to make sure we understand Mewtwo’s Perfection ability, which reads:
“This Pokémon can use the attacks of any Pokémon-GX or Pokémon-EX on your Bench or in your discard pile. (You still need the necessary Energy to use each attack.).”

The main strategy of this deck is to abuse Mewtwo’s Perfection ability to copy specific attacks from Pokémon either in play or your discard pile to take down the opponent’s Pokémon one-by-one. You can do this either by choosing the most efficient attack or using the most appropriate typing to hit the active for weakness. We accelerate energy into play by using Jirachi-GX’s Star Search, similar to how Pikarom decks will use Boltund V’s Electrify attack to throw some energy onto a Pokémon. We want to ensure a solid attack on the second/third turn and then go from there. While this deck doesn’t have a crazy amount of energy acceleration, it is just enough to get things going and threaten a massive OHKO on the following turn.

Key TCG Cards

Mewtwo and Mew Gx

3 Mewtwo & Mew TTGX (“Mewtwo”) – Mewtwo is the star of this show! Only as strong as the attackers you’ll see below, Mewtwo doesn’t play around when it comes to versatility. You’ll see below why it is one of the best decks around by seeing the showcase of attacks it can copy. Choosing your GX attack for each game is something that will be a challenge, but once you play out matchups in detail, you’ll see why it’s amazing. 270HP standing tall, Psychic-typing, and a weakness to Psychic (mitigated by Jirachi-GX), Mewtwo can do it all. Don’t forget that Mewtwo has a GX attack itself in the form of Miraculous Duo, which can heal itself for so much damage. This is often a huge surprise which can cause upsets in games because people forget that Mewtwo has a GX attack all the time. Let’s hop into some of the attackers in this deck!

Garchomp and Giratina Gx

1 Garchomp & Giratina TTGX – A beast in its own right, Garchomp and Giratina have many good attacks to choose from. Sniping for 40 damage with a Linear attack is good. Calamitous Slash can deal a good chunk of damage after a Horror Energy poke can be detrimental to the opponent, and GG End GX can absolutely body certain Pokémon. This is kind of an all-purpose tool and one of our more general attackers.

Incineroar Gx

1 Incineroar-GX – A useful GX Pokémon that can help us to discard Special Energy from play. It is most commonly used in the LucMetal matchup for its GX attack, where it can basically OHKO anything in its path.

Jirachi Gx

2 Jirachi-GX - The Psychic Zone ability on this Pokémon is super valuable here because it turns off our Psychic weakness (and our opponent’s Pokémon, keep that in mind). This is valuable against other Mewtwo decks, or perhaps an attack from a Polteageist. Star Search is an excellent form of energy acceleration that can uniquely search out and attach Special Energy cards, hence why we play a total of eight Special Energy in our deck.

Reshiram and Charizard Gx

1 Reshiram & Charizard TTGX (“Reshizard”) – Another efficient attacker with its Outrage attack, Flare Strike, can also be built up to. We won’t ever really use Double Blaze. Having its Fire-typing also helps us out majorly versus LucMetal, since nothing in their deck can ever OHKO us.

Vileplume Gx

1 Vileplume-GX A two-energy attacker that can efficiently hit for 180 damage.

Gengar and Mimikyu Gx

1 Gengar & Mimikyu TTGX (“Genkyu”) – Genkyu is the king of donks because of its Horror House GX attack and can really slow down the opponent by preventing them from playing cards for a turn. This can be key in many MUs and swing the tempo of games, especially when followed up with a Polteageist attack. This GX attack is one of our many common openers in many games.

Trevenant and Dusknoir Gx

1 Trevenant & Dusknoir TTGX (“Trevnoir”) – Trevnoir does a great job of stealing games against the opponent by either using Night Watch on the opponent’s hand. When combined with Marnie or Reset Stamp, it can be deadly. Pale Moon GX is also a fringe attack that can get amazing OHKOs when timed correctly or when the opponent is out of resources.

Latios Gx

1 Latios-GXLatios-GX has a unique GX attack that can disable ADP decks from using Altered Creation. We can toss it into the discard to bypass Latios’ negative ability.

4 Marnie – This disruptive Supporter, when combined with Trevnoir’s Night Watch attack, can be devastating for our opponent; it brings their hand down to four cards, and then you shuffle away two at random. Yikes! This is a great way for how we can cheese wins out of the opponent.

2 Tag Call – An Item that can help us search out our Tag Team Pokémon while also searching out key Tag Team Supporters.

1 Mallow & Lana – This is yet another interesting inclusion as a 1-of because it can heal a hit in the many matchups, or it can help us reset effects like Reshizard’s Flare Strike attack. Mallow & Lana is reusable alongside Eldegoss V so that you could get the full value out of this card twice! This card works very well with Tag Call since you can search out TTGXs and TT Supporters.

1 Guzma & Hala – An extension of Tag Call, this Supporter makes it easier to search out Chaotic Swell, our Special Energy, Big Charm, and Stealthy Hood.

2 Chaotic Swell – A neutral Stadium card that can prevent Power Plant from shutting down our abilities and slow down Fire-type decks by limiting their Giant Hearth usage. Searchable via Guzma & Hala.

2 Stealthy Hood – Used to prevent Giratina’s Dimension Breach ability, Galarian Zigzagoon’s ability, and most importantly, Mimikyu’s Shadow Box ability which can shut down our entire deck. Searchable via Guzma & Hala.

1 Big Charm – Extra HP is never a bad thing, and in some matchups, you really need it. For example, against Eternatus, they can hit our Mewtwo for 270 damage (which is an OHKO), but with a Big Charm attached, we can avoid the blow and force our opponent to hit us twice. Searchable via Guzma & Hala.

1 Air Balloon – A searchable switch card that you can find with Guzma & Hala.

1 Reset Stamp – I’d really like to play two of these, as they work fantastically with our Pokémon's durability. Reset Stamp is a resource we typically save for the late game, and when you’re spreading damage, the game is typically going to go pretty long. A staple in Mewtwo decks, this disruptive card is a mainstay. It also has synergy with Trevnoir’s Night Watch attack to potentially disrupt our opponent to a zero card hand!

1 Tag Switch – Players have been loving including 1-2 copies of Tag Switch within their Mewtwo decks as it tends to be very potent in setting up new attackers. Tag Switch can be used to move energy off of a damaged Tag Team Pokémon onto a non-Tag Team for longevity (which can pick up surprise KOs in the blink of an eye). Likewise, you can also abort using a damaged Tag TeamPokémon and move that energy onto a fresh Tag Team Pokémon (which sometimes makes for a better investment of energy in general). The drawback of playing Tag Switch is that you can’t move energy off of non-Tag Teams. However, most of the time, I find that I attach my energy directly to my Tag Teams, so this card has a higher risk and higher reward vibe. This is kind of a “one way or the other” type inclusion, so choose wisely, trainer!

4 Horror Energy – This card is one of the best buffs Psychic Pokémon have! This card is essentially Rocky Helmet and a Psychic Energy smushed together, making a great combo. Especially since we do a lot of damage with this deck, we can always take the extra damage from Horror Energy. Pro Tips: You can actually stack this card, meaning if you have two Horror Energy attached to a Mewtwo and the opponent attacks, you’ll deal 4 damage counters to their active Pokémon! Horror Energy can also damage your opponent’s active, which triggers the extra damage clause on Garchomp &Giratina TTGX. Searchable via Jirachi-GX’s Star Search.

4 Aurora Energy – An energy that allows us to attack with a wide suite of attackers. It can also discard attackers for us to strengthen our Perfection ability. Searchable via Jirachi-GX’s Star Search attack.


I’m sure you’re already running to your computer and loading up your PTCGO Codes as we speak, so I’ll let you hop to it. Galaxy Mewtwo is one of the newer Pokemon Online decks going forward into BAS (and it could get powerful due to future threats being weak to Psychic-types), so you might need some more Pokémon TCG online codes to build this deck. This deck will cost quite a few packs considering the set just dropped, so why not consider getting your PTCGO codes from our website?
