The highly anticipated Mythical Island expansion has launched in Pokemon TCG Pocket, introducing game-changing cards that elevate competitive play to new heights. This mini-set brings strategic depth beyond simple collection building.
Pokemon TCG Pocket’s latest release delivers 86 meticulously designed cards to the popular mobile platform. The collection breakdown includes 68 standard numbered cards, six distinct illustration rares, ten special illustration rare variants, one ultra rare immersive card, and a coveted gold crown collector’s piece. While completionists will enjoy the hunt, competitive players gain access to powerful new tools that reshape the current meta landscape.
Our analysis focuses on the most impactful competitive cards that deliver immediate tournament viability and strategic advantages.
Celebi ex
Celebi ex stands as Mythical Island’s exclusive immersive rare variant, offering exceptional value for Grass-type enthusiasts. With 130 HP, this Pokemon maintains battlefield presence long enough to accumulate substantial energy attachments. Its damage mechanic scales dramatically – dealing 50 damage for each energy card attached, creating exponential threat potential.
Pro Tip: Prioritize energy acceleration cards in your deck to maximize Celebi ex’s damage output quickly. Avoid leaving it as your only attacker without backup plans.
Serperior

Serperior transforms Grass energy dynamics through its revolutionary ability that doubles the value of every Grass energy attached to any Grass Pokemon. This synergy creates explosive damage combinations – just two energy attachments on Celebi ex deliver 200 damage instantly. The card also synergizes with established Venusaur ex archetypes, though evolution timing requires careful sequencing.
Common Mistake: Players often bench Serperior too late. Deploy it early to maximize energy doubling throughout the match.
Mew ex

Mew ex maintains its dominant status from traditional Pokemon TCG, seamlessly transitioning its power to the Pocket format. The Psychic-type’s colorless Genome Hacking attack provides unprecedented flexibility, allowing players to replicate any attack from their active Pokemon. This enables access to meta-defining moves from Pikachu ex and Charizard ex without deck inclusion requirements.
Advanced Tactic: Use Mew ex to counter specific matchups by copying opponent strategies while maintaining your deck’s core identity.
Vaporeon

Vaporeon revolutionizes Water deck energy management with its Wash Out ability, permitting unlimited energy transfers from bench to active Pokemon each turn. This dramatically accelerates powerful attacks on cards like Articuno ex and Starmie ex while providing defensive resilience.
Strategic Insight: Combine Vaporeon with retreat strategies – when your active Pokemon takes heavy damage, retreat to bench and instantly transfer all energy to a fresh attacker using Wash Out.
Aerodactyl ex

Aerodactyl ex synergizes powerfully with the existing Old Amber card from Genetic Apex, making it an essential Fighting deck component. Its Primeval Law ability forces opponents to evolve benched Pokemon prematurely, disrupting their strategic sequencing.
Combo Potential: Pair Aerodactyl ex with Sabrina’s supporter effect to seize board control by manipulating opponent’s active Pokemon placement.
Mythical Slab

Mythical Slab represents a strategic breakthrough for Psychic decks, enabling players to peek at their deck’s top card and claim it if it’s a Psychic Pokemon. This item card significantly enhances consistency and accelerates critical setup phases.
Deck Integration: This trainer card proves particularly valuable in Mewtwo ex variants that rely on Gardevoir for energy acceleration, reducing setup time by 2-3 turns in optimal scenarios.
Energy Management Mastery: Proper energy attachment sequencing separates elite players. With Celebi ex, attach energies gradually rather than all at once to avoid becoming priority target. For Vaporeon decks, maintain at least one backup Water Pokemon on bench for emergency energy transfers.
Avoid These Mistakes: Don’t bench Serperior after establishing your energy base – deploy it first. Avoid using Mew ex without understanding opponent’s attack patterns first.
Deck Building Optimization: When incorporating these Mythical Island cards, ensure your deck maintains balance between new power cards and existing consistency engines.
Matchup Specific Adjustments: Against evolution-heavy decks, prioritize Aerodactyl ex to disrupt opponent tempo. Versus aggressive decks, leverage Vaporeon’s defensive capabilities.
