The *Pokémon TCG Pocket* Mythical Island mini-expansion has significantly altered the meta. To help you navigate this new landscape, here are some top-tier deck builds:
This popular deck aims for a swift Serperior deployment. Serperior's Jungle Totem ability doubles the Energy count on all Grass Pokémon, including Celebi Ex, dramatically increasing Celebi Ex's damage output through its coin-flip-based attacks. Dhelmise, also benefiting from Jungle Totem, serves as a secondary attacker. While highly effective, this deck is vulnerable to Blaine decks. If you lack Dhelmise, consider Exeggcute and Exeggcutor Ex as viable substitutes.
Decklist: Snivy x2, Servine x2, Serperior x2, Celebi Ex x2, Dhelmise x2, Erika x2, Professor’s Research x2, Poké Ball x2, X Speed x2, Potion x2, Sabrina x2
This refined launch-day favorite utilizes the Mythical Island expansion to enhance its core strategy. Koga's ability to bounce Weezing back to your hand provides a free retreat and allows for repeated Poison attacks. Whirlipede and Scolipede boost Poison consistency with their Poison Sting attack. Leaf further facilitates Pokémon movement alongside Koga.
Decklist: Venipede x2, Whirlepede x2, Scolipede x2, Koffing (Mythical Island) x2, Weezing x2, Mew Ex, Koga x2, Sabrina x2, Leaf x2, Professor’s Research x2, Poké Ball x2
Mew Ex's inclusion significantly improves the Alakazam deck's consistency. Mew Ex provides a sturdy early-game presence with Psyshot and Genome Hacking, allowing time to set up Alakazam. Budding Expeditioner facilitates Mew Ex's retreat. Alakazam effectively counters the Celebi Ex/Serperior combo, dealing increased damage based on the opponent's Pokémon's Energy count, even factoring in Jungle Totem.
Decklist: Mew Ex x2, Abra x2, Kadabra x2, Alakazam x2, Kangaskhan x2, Sabrina x2, Professor’s Research x2, Poké Ball x2, X Speed x2, Potion, Budding Expeditioner

The enduring Pikachu Ex deck receives a boost with Dedenne, offering strong early-game attacks and a chance to inflict Paralysis. Blue provides much-needed defensive support to compensate for Pikachu Ex's low HP. The core strategy remains the same: fill the bench with Electric Pokémon and unleash Pikachu Ex's power.
Decklist: Pikachu Ex x2, Zapdos Ex x2, Blitzle x2, Zebstrika x2, Dedenne x2, Blue, Sabrina, Giovanni, Professor’s Research x2, Poké Ball x2, X Speed, Potion x2
