The development team behind Pokemon TCG Pocket has experienced a significant security breach, resulting in the entire trailer for the forthcoming Secluded Springs expansion being prematurely revealed to the public. This unexpected leak showcases approximately a dozen never-before-seen cards that will debut in this highly anticipated update. Mere hours before this incident, the game's official Google Play and App Store listings had already accidentally disclosed information about the previously unnamed A4a set, including its scheduled release date and featured Pokemon roster.

Prior information had already confirmed that the next major update for Pokemon TCG Pocket would center around the legendary trio known as the Sacred Legends: Suicune, Entei, and Raikou. An earlier artwork disclosure had already presented these three majestic creatures, with Suicune positioned prominently in the center, suggesting its status as the primary mascot for this collection. The recent leak has now exposed additional Pokemon that will appear in the A4a mini-set expansion.

The security lapse appears to have originated from the official Korean Pokemon YouTube channel, which accidentally published the complete teaser trailer for the A4a set before its intended reveal date. This mishap resulted in twelve unreleased cards becoming publicly visible. Although the video has since been removed from the official channel, dedicated fans have managed to capture screenshots and footage that continue to circulate through various unofficial channels and community platforms. Dubbed Secluded Springs, the A4a collection seems to include several intriguing cards featuring the legendary beasts, each possessing unique card-draw capabilities according to preliminary translations.

Complete List of Leaked Pokemon TCG Pocket Cards from Secluded Springs

The comprehensive leak includes the following confirmed cards:

• Suicune EX
• Entei EX
• Raikou EX
• Mantyke
• Slowking
• Milotic
• Latios
• Latias
• Phanpy
• Slugma
• Stunfisk
• Traveling Merchant (Supporter card)

The Pokemon community has expressed divided opinions regarding the functional mechanics of Suicune, Entei, and Raikou, as their described abilities appear somewhat ambiguous based on current translations. Preliminary information suggests that all three legendary cards allow players to draw additional cards from their deck during gameplay. The primary uncertainty revolves around whether this ability activates when the Pokemon is on the Bench or exclusively when positioned in the Active Spot. If these capabilities function from the Bench position, these legendary creatures could potentially become essential components in most competitive decks within the Pokemon TCG Pocket metagame.

As many enthusiasts predicted, Latios and Latias feature interconnected abilities that enhance each other's capabilities when both are present on the battlefield. The leak also reveals a new Supporter card, tentatively identified as the Traveling Merchant, which enables players to retrieve Pokemon Tool cards directly from their deck. Another notable inclusion is Mantyke, a new baby Pokemon believed to serve as a ramp card specifically for Water-type decks, as it can generate Water Energy and attach it to Basic Pokemon of the same type.

It is important to emphasize that these card descriptions and abilities have been translated using automated tools and may contain inaccuracies. Similar to previous Pokemon TCG Pocket leaks, current speculation might ultimately prove incorrect or misleading. The positive aspect is that the official A4a teaser trailer is expected to launch on August 22 or 23, meaning international fans won't need to wait extensively to discover the complete contents of these new booster packs.
