Mythical Island (A1a) Set Guide: Pocket's Single-Pack Mini Set

Mythical Island holds 86 cards in total, with 77 being Pokémon cards and 14 of those ex versions — noticeably smaller than Genetic Apex's 286-card pool. That smaller pool matters directly for Pack Point planning: with fewer total cards to pull from at each rarity tier, redemption thresholds land the same (still 500 points for a Double Rare) but the per-slot odds of hitting any one specific card within a shared rarity bucket are a little higher than in a deeper set, simply because there's less competition within the pool.

Where Genetic Apex splits into 3 packs, Mythical Island is opened entirely through a single pack — Mew — covering all 86 cards. That means there's no pack-selection decision to make within the set the way there is with Genetic Apex's Charizard/Pikachu/Mewtwo split; every Regular Pack or Rare Pack opened from Mythical Island pulls from the exact same 86-card pool.

Mythical Island's Crown Rare is Mew ex (130 HP, Psychic), and its Immersive Rare is Celebi ex (130 HP, Grass) — a clear thematic shift from Genetic Apex's Kanto-starter-and-legendary chase cards toward the Mythical Pokémon the set is named for. At the Double Rare tier, its strongest ex Pokémon by HP are Gyarados ex at 180 and Pidgeot ex at 170, giving the set a couple of genuinely tanky attackers below its top chase tier too.

Because Mythical Island's entire pool routes through one pack, it's a straightforward set to farm with total focus if Mew ex or Celebi ex is specifically what you're after — there's no pack-mix decision diluting your pulls. If you're working through Pack Point redemption instead of chasing pulls directly, the smaller 86-card pool also means your points accumulate toward a proportionally shorter list of cards to actually complete, compared to farming a full 3-pack set like Genetic Apex.

Across Mythical Island's 77 Pokémon cards, Grass and Psychic tie for the largest groups at 13 cards each, followed by Fighting at 11 and Water at 10 — with Dragon sitting at just 1 card total. Because the whole set funnels through a single pack, this spread is also exactly what you'll see reflected in your pulls regardless of strategy; there's no alternate pack with a different type lean to switch to the way Genetic Apex offers between its three.

Since Mythical Island's card count is small enough that a legal 20-card single-type deck built purely from it can feel thin outside of Grass or Psychic, most decks that use Mew ex or Celebi ex pair them with Basics and support Trainers pulled from a deeper set like Genetic Apex or Space-Time Smackdown rather than staying mono-set. Mixing sets for deck-building doesn't cost you anything extra — Pack Points and deck legality are both independent of which set a card originally came from.
