Pokémon TCG Pocket is more than just a mobile collectible card game — it’s a race for dominance and rarity. While many players aim to build the most powerful decks for competitive play, the real thrill lies in collecting all the cards. But among hundreds of options, one card stands out as the most elusive and challenging to obtain.
Mew from “Formidable Genes” Is the Hardest Card to Collect
Despite the wide variety of rare Pokémon cards in the game, Mew from the “Formidable Genes” set (#283) is widely regarded as the most difficult card to acquire. It holds a 3-star rarity, which isn’t the highest in the game — that distinction goes to Crown cards — but its acquisition method sets it apart from the rest.

To obtain Mew, players must collect all 150 Pokémon from the Kanto region within the Formidable Genes set. This is a massive challenge that requires persistence, game knowledge, and a significant amount of time — if not a financial investment.
Why Mew Will Only Get Rarer Over Time
Mew’s current rarity already makes it a sought-after prize among serious collectors, but its future scarcity could be even worse. As the game continues to evolve and move toward new set releases, such as Set 2, many of the booster packs from Set 1 will gradually disappear from circulation.
This shift means that players who are missing Kanto Pokémon now may lose their chance permanently to complete the Formidable Genes collection. Over time, Mew will become a collector’s trophy few will ever own.
The Crown Cards: The Rarest Pokémon in TCG Pocket
While Mew is the hardest card to get based on conditions and requirements, Crown-rarity cards are technically the most exclusive based on drop rates alone. These cards often come with unique designs, animated art, or iconic status, which makes them extremely difficult to pull from packs.

These cards are the top-tier collectibles for players chasing the ultimate Pokédex. They appear in the game with visually distinct golden crowns and are mostly found in limited-time events or ultra-rare booster packs.
