S Tier

Suicune ex Greninja

Using only Water energy, the deck revolves around A4a-020's draw ability to rapidly evolve A1-087 into A1-089, creating a powerful engine that draws cards while dealing consistent damage. A4a-020 can also attack when needed. A2b-035 serves as additional reach, providing late-game knockout potential once the early setup is complete.

Giratina ex Darkrai ex

The deck sets up two staggering win conditions by fully charging A2b-035 with its Ability and manually attaching to A2-110. With only Darkness Energy, A2b-035 powers itself while A2-110 chips away each turn — once both are online, the pressure becomes overwhelming.

Guzzlord ex

Open with Guzzlord as you carry which can use Grindcore in the early game to possible remove energy from your enemy until you can use Tyrannical Hole to deal 120 damage. Use your Trainers accordingly.

A Tier

Espeon ex Sylveon ex

Get A4-083 online as soon as possible and start swinging for 80 with just 2 Energy. Thanks to its healing ability and A2-147, A4-083 is extremely hard to one-shot.

With A3b-034 helping you get set up quickly, and Supporters, you can consistently take control of the game.

Flareon ex Eevee

Only using Fire Energy. You try to evolve into A3b-009 right away as your main damage dealer. A4-032 can provide energy for Flareon ex or A1a-019. A3a-061 is an additional draw option to make the deck more consistent.

Silvally Rampardos

Always start with Type:Null then evolve into Silvally to deal 100 damage every turn with a Supporter. Evolve Fossil into Rampardos as your other damage dealer.

Darkrai ex Arceus ex

Using only Dark energy, the deck uses baby Pokemon generators to accelerate A2a-071 and A2-110 setup while creating immediate pressure. Starting with any baby Pokemon, you charge your main attackers. A2a-071 paired with A2b-071 easily hits 140 HP breakpoints, while A2-110's ability can push damage up to 170. A3-141 provides additional utility when going first or against A3-066 matchups.

Buzzwole ex

The game plan usually starts with A3a-007 or A3a-008, chipping away while you set up A3a-006 to swing with Big Beat for 120 damage. A3a-069 helps accelerate this if needed. Once you’ve attacked, you’ll typically switch out A3a-006 with A3a-062, then retreat back to A3a-006 to attack again. A3a-062 also gives you the flexibility to switch out itself or A3a-006 if you open with them, letting you pivot cleanly into A3a-007 early on.

Tapu Koko ex Oricorio

Either start with Tapu Koko ex that can use Plasma Hurricane and get energy for Mach Bolt dealing 90 damage or with Oricorio letting you protect against EX cards.

Dragonite ex Sylveon ex

Using only Water energy, we use Pichu as our Lightning generator to give it to Dratini. Evolve Dratini into Dragonite using Rare Candy and deal damage. Eevee into Sylveon is our access to more draw to evolve Dragonite.

B Tier

Raikou ex Tapu Koko ex

Use A4a-025's Legendary Pulse to draw through your deck and access trainers quickly. Generate energy with A3a-021, then use A4-151 to move energy between attackers for flexible responses. Close games with A2b-022's high damage output.

Greninja Oricorio

Running Water and Lightning energy, you try to assemble A1-089 to start hitting with its ability.A3-066 as your hitter and wall against EX decks, while A2b-035 can serve as another option as a damage hitter.

Arceus ex Oricorio Pichu

A4-066 can start generating energy for any of your Pokémon, even A2a-071. A3a-021 can charge energy on its own at the start, making for a good turn 1 play. A3-066 serves as your backup option against EX Pokémon, while A2a-071 is your main damage dealer.

Silvally Oricorio Pichu

Start with A4-066 and give Energy to A3a-060 or A3-066, which will then be able to attack next turn since you can retreat A4-066 for free.

Raikou ex Magnezone

The deck leverages A4a-025 as both draw engine and bench damage dealer while building toward A2-053 as the primary win condition. A1-098 generates Lightning energy through its ability, setting up massive A2-053 attacks with enough energy accumulation. A3-066 provides crucial backup against EX-heavy matchups, while double A2-150 becomes more effective thanks to A4a-025's bench damage creating better knockout opportunities.

Guzzlord ex Naganadel

A3a-044 is your ideal starter, then evolve into A3a-045 to deal damage and apply Poison right away. With the help of A3a-042's ability, you can increase the damage from Poison. A3a-043 serves as your backup damage dealer or Energy removal option when needed.

Tier Explanation

To create this Meta Tier list, I used data from tournaments and my expertise and opinions of respected players. This tier list will hold meta-staple decks that you'll likely encounter in tournament play and will be updated as the meta changes up.

The decklists shared here have found success in tournament events but can be tweaked depending on meta shifts or players' preferences.
