Pokemon TCG Pocket A4a Leak: Legendary Beasts Lead an August 28 Mini-Set
The next mini-set for Pokemon TCG Pocket has reportedly leaked, and it’s shaping up to be a fan-pleasing drop. An early listing on the Google Play and Apple App Store briefly mentioned an event starting August 28, pointing to the arrival of the A4a collection. Beyond a predictable release cadence, this leak hints at a powerful mix of iconic Legendaries and cross-region picks that could shake up both the meta and collectors’ priorities.

What Was Leaked: The Headliners and Surprises
According to the briefly published store post and subsequent community chatter, the following Pokemon are featured in the A4a mini-set:
- Entei
- Raikou
- Suicune
- Latios
- Latias
- Poliwhirl
The marquee trio of Entei, Raikou, and Suicune immediately sets a tone for high-impact, Legendary-driven gameplay, while the presence of Latios and Latias suggests the set won’t be constrained to a single region. The event artwork also appears to spotlight Poliwhirl, hinting at either a reworked card or renewed support for its evolutionary line. As always with leaks, details can shift before the official reveal, but the lineup is consistent with past early teases for Pocket’s A-series.
Release Timing: A4a in Late August, A4b Likely in September
Players have gotten pretty good at reading Pocket’s release rhythm, and this leak fits the pattern. The A-series has rolled out in steady beats, with A4 already positioned as a “journey to Johto.” The new info places A4a on August 28, followed by A4b in September, which many believe will serve as the final stop in the A-series. If rumors pan out, the game’s first anniversary could usher in the B-series—potentially a fresh era for Pocket’s meta, card design, and collection goals.
It’s also worth noting earlier chatter suggested a focus on Baby Pokemon for a supplemental drop. While those cuties have already made their way into the digital binder, there’s another anticipated milestone on the horizon: Mega Evolution has been rumored for a fall window. If true, A4a and A4b may act as a bridge into a much bigger mechanical shake-up later in the year.
Cross-Region Curation: Why A4a Isn’t Just Johto
On paper, A4 has been about Johto, but Pocket’s curation has never been rigid. The Latios/Latias sightings suggest a deliberate cross-region blend—Johto’s Legendary Beasts paired with Hoenn’s Eon duo. This approach makes sense for a live-service card game: it provides the balancing flexibility developers need to shore up archetypes, experiment with new effects, and keep each mini-set relevant to the evolving metagame, without being boxed in by regional themes.
Meta Watch: What These Cards Could Mean for Your Decks
Until the official card texts drop, consider the following as informed speculation grounded in longstanding Pokemon TCG tropes and Pocket’s recent design tendencies:
- Entei (Fire) – Often positioned as a high-pressure attacker with above-average damage ceilings. Expect synergy with Fire acceleration and the potential to capitalize on Burn or on-hit pressure. Could revitalize Fire shells that have lagged behind Water and Lightning openings.
- Raikou (Lightning) – Traditionally associated with speed, draw smoothing, or Bench-targeting. In Pocket, a quick-strike Lightning threat could re-center tempo and punish slower builds. Watch for interactions with existing energy ramp or multi-attach effects.
- Suicune (Water) – Often appears as a durable pivot or efficient attacker with incidental draw. If Pocket leans into survivability or mobility tools, Suicune might anchor Water’s midrange strategies and counter aggro spikes.
- Latios & Latias (Psychic/Dragon-adjacent flavor) – These two frequently play off each other via tag synergies, support abilities, or flexible attacker/support roles. Expect teleporting-style effects, setup smoothing, or conditional boosts when tags are paired on the board.
- Poliwhirl – A Stage 1 that could serve as a glue piece for the Poliwag line, possibly enabling utility such as status or tempo disruption. A reworked Poliwhirl might nudge a full Politoed line into viability.
Reminder: exact effects and power levels are unknown until the official reveal. Still, the lineup suggests diverse archetype support rather than a single-deck miniset, which is healthy for both ladder variety and the game’s long-term balance.
Collector’s Corner: What to Watch for in A4a
Even if you’re more binder-focused than ladder-minded, A4a looks like a prime pickup window. Keep these points in mind as you plan your pulls:
- Set code and rarity spread – The A4a code will matter for future trade value and organization. Keep an eye on how rarities are distributed among the Legendaries.
- Event artwork – Pocket’s event art often hints at special frames or unique visuals. The Legendary Beasts and the Eon duo are prime candidates for standout art treatments.
- Reworks and line support – If Poliwhirl truly gets a rework, the Poliwag line might see renewed interest. Track evolving lines; they can become sleeper hits for collectors.
- Dupes and trade timing – Don’t rush to offload duplicates on day one. Prices and trade value usually stabilize a few days into the event once drop rates and chase cards are clear.
How to Prepare for A4a’s Launch
- Bank your currency – Save gems and tickets now so you can frontload pulls on day one.
- Clear dailies and missions – Stockpile rewards the week prior; it’s “free equity” for your A4a opening.
- Audit your decks – Identify which archetypes would benefit from Fire, Lightning, Water, or Psychic/Dragon-adjacent upgrades. Plan target lists.
- Watch the teaser – A trailer is likely imminent, and it often confirms mechanics or featured art tiers.
- Manage inventory – Free up binder space and organize by set to make post-pull sorting painless.
- Set trade goals – Decide which Legendaries you’ll chase via trades versus packs, and prepare fair offers.
- Budget wisely – If A4b lands as expected in September, pace your spending so you can engage both drops.

Why This Leak Tracks: A Quick Look Back
This isn’t the first time Pocket has sprung a leak. Back in July, an early teaser for A4 slipped out and led to a 14-card reveal ahead of schedule. The A4a post appears to be a similar premature listing, likely meant to go live alongside an official teaser. It’s consistent, if a bit chaotic, and the community has learned to treat these moments as early warning signals rather than gospel. Still, the August 28 timing is credible enough to mark your calendar.
Where to Play Pokemon TCG Pocket
You can play Pokemon TCG Pocket on mobile via the Google Play Store (Android) and the Apple App Store (iOS). Search for “Pokemon TCG Pocket,” download, and you’re ready to build decks, open boosters, and trade with the community. If you’re returning after a break, this is a great moment to jump back in—A4a looks poised to inject fresh life into the ladder and the market.
Final Thoughts: A4a Sets the Stage for a Big Fall
A4a has all the ingredients of a crowd-pleaser: beloved Legendaries, cross-region flavor, and the potential to energize multiple archetypes at once. If the roadmap holds—A4a in late August, A4b in September, and a rumored B-series around the anniversary—Pocket’s end-of-year arc could be one of its most exciting yet. Whether you’re here to climb the rankings, fill your binder, or both, get your resources in order and be ready to make some noise when the Legendary Beasts roar onto the scene.
